WARNING: The GTX 680 is **SLOWER** than the GTX 580

The results are in -- and the 680 performs horribly for GeneferCUDA.

It is significantly slower than a GTX 580 when running the GeneferCUDA application. The GTX 680 has severely crippled double precision speeds, and that's what's used by GeneferCUDA (and also llrCUDA).

If you're looking to run Genefer, the GTX 500 series GPUs are the best. Stay away from the Kepler (600 series) GPUs. I expect the 500's to drop in price, and they're better suited for this application than the newer cards.

Well, at least the 600 series will cause a price drop in the 500 series.

This is unfortunate though. I was hoping for significant speed increases from the 600 series.

Tom's Hardware Guide have 2 features benchmarking on the 680.

It is stated that particular model is suited to gaming, not DC processing.

I was expecting this. NVIDIA has always geared their progress towards gaming.

It's ATI's time to shine.

If you consider power consumption, then the 680 is an option to consider. 190 watt max is less than a 560 ti (the normal ones, not the new 448 cores). When running a gpu at full load on a 24/7 basis in Europe, that can be an important factor.
In previous gtx series, new drivers allowed great improvements of computation speed. I'm not sure if that will also happens with kepler cards, though. In that case, seeing the DP computation equivalen to a 570 on a 190 w TDP card would still be a nice feat.

I got a 680 today and will test it tonight on an AM3+ 5xSlot PCIe Board with 8core-Black-edition Bulldozer-CPU and 32GB highspeed DDR3 Ram (needed for Neurona @ Home perhaps in future). First Test on Win7x64, second on Linux.

Atm I'm testing a gtx560ti (448 Cores) with q6600 and 8GB DDR2 non-OC (24/7 stresstest). For PPS-Sieve its fine (ca. 15-17 Minutes/WU - up to 300.000 Points/Day inclusive WUs on CPU).

I guess (guess!) the 680 will be much faster in praxis. If so, I will order a second one next week and will post real scores for Genefer(short&long), too. My board can handle up to three 680 with 1200W "powerplant* ;) in x16-Mode. An average Output of 1 Million+ points/day (like the Nr.1 in Top-Computers (Tesla)) should be possible/reachable. (I guess!)

Please don't ask for my energy-bill *rolleyes* I know, its quite crazy and shure I know there are much cheaper mini-ATX-cluster in Green-line build by [Seti-Germany], but Primegrid is worth to spend some bugs into this hobby and science. Like other, who spend much more than me for Boinc by using brutal-expensive Tesla-Cards or newest Opteron-Server. That guys have my respect, because a lot of people talk about future, but only some realy crunch for.

I posted some times in this thread: http://www.primegrid.com/forum_thread.php?id=4044&nowrap=true#51950

I ended up swapping the 680 for 2x570s.

My only problem could be the power-consumption of two or more 590 on one board. So I'm testing 560ti and 680 cards.

@sheridan:
You wrote in the other thread:

CW Sieve: gtx580 overclocked to 860MHz = 304s
gtx680 = 265s.


Do you use the 680 in non-OC/factory speed?
How long does a PPS-Sieve task run with your equipment?
What kind of OC-Software do you use for 580? MSI-Tweaker or the normal Nvidea Stuff? (ok, insidertalk ;))

Well, your RAC is extreme. *thumbs-up* I guess, I could reach it with 1x560ti + 2x680 in ONE PC, but I'm not shure if the power consumption will blast the 1200W ...
Someone tells me, there should be a company in England selling "handmade" 2000W stuff. But the Price near 1000 Euro is crazy - also for me too crazy.
So there are three possiblilities I have to test:
a) hunt the RAC-Record with one machine or
b) as user
c) for team

The 680 was running standard speed, the 580 is overclocked using msi afterburner.
Not sure about PPS sieve times as I didn't try any of those.

My PSU is also 1200W so I can say you'll have no problem with running 2 cards on yours but 3 might be pushing things a little. However, there's some 1500W psus out there that won't break the bank.

Well, I have other results:
My 560ti: http://www.primegrid.com/result.php?resultid=365318852
My GTX680: http://www.primegrid.com/result.php?resultid=368009198

560ti:gtx680 (in PPS Sieve / Vista64) 1053:689 sec.

680 is non OC / 560ti is factory-OC

CPU-Time or overall-Time?
The praxis is important, but not the theory. More Points per KW/h rules. ;)

The 680 was running standard speed, the 580 is overclocked using msi afterburner.
Not sure about PPS sieve times as I didn't try any of those.

My PSU is also 1200W so I can say you'll have no problem with running 2 cards on yours but 3 might be pushing things a little. However, there's some 1500W psus out there that won't break the bank.


You didnt try PPS sieve (Cuda)? So how you reach a red badge in PPS sieve? Only by CPU-crunching? ;)
The 2nd 680 arrived. First I need a big(ger) tower and cooler ...

btw: My new Bulldozer FX8150 has made its first test in Germain-Contest. Quite good on 3,6ghz non-OC - Team rank 63. :)

edit@ Michael: Sorry, you talked about the lag in GENEFER. I talked about PPS sieve. My fault.

You are right, but GeneferCUDA needs DP and looks like performance of DP at 680 GTX is only 1/24 of FP32, while 580 GTX has FP64 performance = 1/8 of FP32

I see. I excuse myself before (to Michael) for talking about PPS sieve instead of Genever. ATM Im crunching a long Genever Task ... lets see how long it needs in practice ...

I got the badge last year. I didn't try running any PPS Sieve on the 680.

Real Numbers so far: 10,08% in 13:04 hours. I guess 130h overall ... would that be good or not good?

As you can see, an i7 and x5560 with gtx580 and Quadro2000 have failed so far ...

The estimated run time in stderr.txt should be accurate to within approximately 0.5%. It has nothing to do with the number of times you've run Genefer.

I'm not referring to what BOINC reports; as you said, that's useless. But in the slot/# directory, the stderr.txt file (which only you have access to until the task completes) contains an estimate of the run time. That estimate is extremely accurate.


Real Numbers so far: 10,08% in 13:04 hours. I guess 130h overall ... would that be good or not good?


It would be good -- but it's also slower than a GTX 580. The overclocked GTX 580 that failed would have finished in 88 hours.

As you can see, an i7 and x5560 with gtx580 and Quadro2000 have failed so far ...


Indeed they did. But the reasons why they failed are far more interesting. Both failures were almost certainly preventable by the user. One likely failed because he's using the 295 video driver and the monitor went to sleep, and the other probably failed due to overclocking.

That quadro 2000 was my wingmate on my genefer WR .
He ran1 for 800,000 seconds 1 for 188,000 seconds,
but now flys through about 24 a day erroring out
after 3600 seconds (295 driver).

That quadro 2000 was my wingmate on my genefer WR .
He ran1 for 800,000 seconds 1 for 188,000 seconds,
but now flys through about 24 a day erroring out
after 3600 seconds (295 driver).

john3760


Which is much better going through 100s every day, erroring out after only a minute or two, which is what would happen if Genefer didn't intentionally wait an hour before declaring that error. :)

From what I hear, fixing this bug IS a priority at Nvidia, so hopefully it will be fixed in the not too distant future.

Ok, you convinced me. I gave the 2nd 680 back and got a 2nd 560ti (448) instead. The price/performance ratio is better. Thus I saved also money, in order to buy large exhausts (or Watercooling ... ) I guess in OC-mode the 560ti will be as fast as the 680 (in PPS sieve).

Thus screw again ... for a running 2x560ti+680 system in hopeful nearly future.

BTW: Genefer WC atm 17.47% in 22:23h on 680. Could be a waste of time and energy, but I would like to get a badge first without the risc to touch a running system. ;)

A realization about 680 after a week of testing: It's possible to "reach" the arithmetic performance of the 680 approximately (in PPS sieve CUDA) with a non-OC 560ti(448) in practice. ("Hint": Never touch a running system at all! ;))
The 680-strength is movieediting (premiere/Magix) and the calculation of filters in photo series. For 3D-games (or 3D-art like DAZ) this card is outstanding suitable. With actual drivers the 680 is unfortunately not the best choice to run PPS sieve or Gernefer ... but perhaps some day there will be an APP that profits from the big and fast memory and the outstanding number of cores, like games or picture/videoprogramms allready do ... [in EVE-Online i.e. the 680 is up to 2x faster (framerates) than the 560ti (practice-test)]

All in all: 680 is too expensive to use it for PG only. The price/performance ratio of 560ti is imho much better. A comparison to 580 I cannot give, since I dont have one - but I guess, the 590 is the "Tower of Power" at the moment (as long we dont speak about Tesla <-*dreaming* or other stuff, which a "normalmortal" cannot finances. ;)).

Genefer WR ended without capital errors after 130h on NON-OC GTX680.
http://www.primegrid.com/result.php?resultid=368039342
The programmers seem to be funny, because of:
"Terminating because BOINC client requested that we should quit."
(really? Should we qiut?) *lol* and
"22:57:59 (3484): No heartbeat from core client for 30 sec - exiting"
(no heartbeat? Whats this? Computer or medical science? Ok, in real life I write SF-Stories and some of my robot-figures have no real heartbeats, too - but ...)
*joking* ;)

Well, 130h for Genefer WR is the real&practice performance of a non-OC gtx680, Driver 30083, Boinc 7.0.23, Vista64 home and AMD FX 8150. So this card is atm really too "slow" for THIS tasks. BUT: THIS card existed the test. *end-of-test*

Congrats on that! Once your wingman completes that should be worth 313807.79 credits.

I definitely wouldn't say it's "too slow". It's still one of the fastest GPUs out there. A GTX 460, for example, will do that WU in 220 hours. It's just not the absolute fastest card for Genefer.

Hi, Michael

Slowly in stating lines ;). 300.000+ points would be nice and worth for such a long task. (Even if the 680 would have produce 1.500.000 in the same time with PPS sieve. I'm here to learn something about math-science and test hardware in a material work surrounding field. I've never trust commercial test reports. ;))

You talk about "the absolute fastest card for Genefer". What's your personal opinion? GTX590 or TeslaXXXX? Which one is the "very best" for WR-crunching AND PPS sieve to reach in combination the breakeven of 1mil-RAC?

For Genefer, I think the GTX 580 can do a WU the fastest. The 590 obviously can do 2 WUs at once, but the 580 is clocked faster. A pair of 580s will do 2 WUs faster than one dual-GPU 590.

As for Tesla, I don't know. I have seen contradictory results from Tesla cards and really don't know what the real truth about them is.

As for PPS sieve, I have no idea.

His (or her) output (aprox 360.000 sec.) is very fast.
So what's the different to 580/590 in practice? (Sure Tesla-cards are very expensive - what do you think about the ratio?)

Those times seem to be roughly similar to a GTX 580, about 2 to 3 hours for the short WUs and about 100 for the long WUs. I don't see the huge increase in speed I would have expected from a Tesla.

My [unknown] genefer-WR-wingman uses [2] NVIDIA Tesla C2050 (2635MB) driver: 27565.
http://www.primegrid.com/show_host_detail.php?hostid=215389
His (or her) output (aprox 360.000 sec.) is very fast.
So what's the different to 580/590 in practice? (Sure Tesla-cards are very expensive - what do you think about the ratio?)

best regards,
ritch



Those times seem to be roughly similar to a GTX 580, about 2 to 3 hours for the short WUs and about 100 for the long WUs. I don't see the huge increase in speed I would have expected from a Tesla.



A big part of it is the clock speed...1544 (GTX580) vs. 1150 (Tesla) is a huge difference. This matches roughly the ratios for the Quadro 4000's I ran for a bit with times that were more like a GTX 460.

Thanks for your opinion and experience.
So I ask myself, why Tesla-Cards are so expensive, if a "cheap" 580 can reach them ...

My next Genefer-WR-Test will run with two identical 560ti(448). As in the other thread recommended with previous update to 300xxx driver and all powersavings off (on Win7/64-Ultimate to use the full memory in backround - Yeah, I'ver learned it HERE - thx you! ;-)).

Therefor I have two questions:
1) Normaly I use SLI for work (movie-editing, 3D-animation) because two cards are in practice twice as fast and three have a factor up to x2.8 (in one PC/Workstation). Whats about SLI in PG? Recommended or not? How does PG count this cards - as [1] or [2] in SLI-mode?
2) Whats about the PCIe BusSpeed? Is there any difference between crunching on x16 or x8/4/2 in practice? (My new MB has 5 PCIe from x16 down to x2).

best regards,
ritch

As for PPS sieve, I have no idea.

Performance hint: GTX 680@1097 ~12.94M p/sec, GTX 570 does ~7.5M p/sec, GTX 580 does ~9M p/sec. GTX 580 needs about 30 hours to do a 1T range.

Commercial/Professional level cards have additional functionality in them to guarantee calculations, no errors are tolerated (at all, to a very high level of precision) with many commercial and Real Time systems. Completely different need and resultant design compared to consumer level cards.

Its extremely rare, I've never seen a case, to find the Tesla level/Commercial level card worth the cash for consumer level BOINC-like tasks. Its a totally different market place, requirement and design, its chalk and cheese - pointless trying to compare - and pointless buying one compared to consumer level cards for BOINC crunching, dont even think about it.

@Honza: thx for your practice-comparision. My 560ti(448) does 300.000+ Points per day (PPS sieve) atm in non-OC-Mode. I guess that card is clockable to reach my 680 and in Dual (SLI?) its outstanding too ...
PS: Your RAC [1.8m+] is really outstanding! RESPECT!!! I would like to reach "only" 1mil as user or with one computer. ;) My teamwingman has a nice machine too, but he didnt use the full potential of 6 cores and brutal ATI atm ... perhaps some big Teams would like to recruit us in subdivision before we reach a place in the PG-Top-50? ^^ *joking* (joking? No joking - tomorrow we are in the top-50 in Germany and next month in the top-25, I promise. ^^)

@Zydor: I dont "think about" Tesla - I dream of it. ;)) And sure I would USE a Tesla for other tasks than PG ... but also for fun and test it here, too. The price is "exorbital". Professional stability - ok, but it's imho not worth in daily work to pay SO much money for that, as long you dont produce movies for hollywood. (imho) The practice of movie-editing is: The hard- and software is allredy faster than the human editor. So it would be better (in this case) to invest in humans than machines. ;)

ritch, don't get fooled by RAC, it does not represent real daily output.
(note that PSA credit are in batches).

btw, dual GTX470 (when overclocked) does more than GTX 680.

As of TOP 50 and similar. Personally, I think my days are gone and it ended with GPUs.
I used to be #4 - back in CPU days...2 years ago. And it was when PG was not my main focus.
Now I'm fighting at Top prime finders stage :-)

Hi Honza

Sure, the real (aprox) daily output I can see here:
http://boincstats.com/stats/team_stats.php?pr=pg&co=Germany&st=0&or=12
Other RACs are counted over week, 30(?) or 60 days, right?

I remember to my beginning 1999 to 2002 in SETI. To reach highscores at that time, a serverfarm was a must and unpayable for normal users. Today all that nice and powerful machines from "yesterday" (i.e. Tyan or IBM-Server) have no chance anymore without a PCIe bus.
So I ask, why there are no Cuda-Cards for PCI or AGP bus to reactivate all that "outdated" machines? And why not all projects could profit from GPU-crunching?
Whats the problem? Someone talked about CUDA for llr (there is allready a BETA PPS llr on PG) but I never got a task of it. Too much errors or too less performance/energy ratio - or its because of the scheduler which cant handle so much results in time? I dont know - so I have to ask.
Sure I know that BOINC has the philosophy to use "unused" potential arround the world and that there are enough possibilities to setup BOINC to dont produce handicaps in the backround of normal daily work. (i.e. working with Openoffice there is no feel of lag when BOINC works in backround and I guess most of machines worldwide are used for Office and normal browsing.)
So its a question of energy, because energy becomes more and more espensive or its a question of programming and the problem to programm a better ratio (because of money?)?

Because the people who run Nvidia and AMD know how to run a business. You're looking at this from the perspective of number crunching -- but that is NOT their business. They sell graphics cards to game players. Who, in their right mind, would buy an expensive graphics card and then hobble it in a computer that was unsuitable for playing games? There's no market for such a device. That's why they don't make them.

Someone talked about CUDA for llr (there is allready a BETA PPS llr on PG) but I never got a task of it. Too much errors or too less performance/energy ratio - or its because of the scheduler which cant handle so much results in time? I dont know - so I have to ask.


At the present time it's not fast enough to be worth running.

So I ask, why there are no Cuda-Cards for PCI or AGP bus to reactivate all that "outdated" machines? And why not all projects could profit from GPU-crunching?


Because the people who run Nvidia and AMD know how to run a business. You're looking at this from the perspective of number crunching -- but that is NOT their business. They sell graphics cards to game players. Who, in their right mind, would buy an expensive graphics card and then hobble it in a computer that was unsuitable for playing games? There's no market for such a device. That's why they don't make them.


And the statement that there are no PCI or AGP cards is not correct. AMD (or ATI) has made both PCI and AGP cards that are OpenCL capable and could run the PPS sieve here at PG. NVidia has never made AGP cards in the CUDA capable series, but PCI versions do exist. These cards generally, however, do not have double-precision capabilities, and thus, would only work on the sieve projects.

Mike is also correct here regarding the business/market-driven aspects of GPU manufacturers. The PCI cards are not made to keep outdated machines going, but rather to be used in various specialty (often ultra low-cost business machines, etc.) that are made more cheaply by having no PCIe bus (some cards are also made with PCIe 1x rather than 16x connectors for the same reasons).

Not in general, but really rare. For AGP only Radeon HD3850 and the really rare Radeon HD3870 support DP. At PCI-Slot I'm running Nvidia GT430 in some of my hosts also with DP capabilities. In the past there running successfully the short genefercuda ;) Also the Nvidia GT520 with DP is available with PCI.

I've never seen those cards before, but your are right.

I've tried to use a 38xx (3870-PCIe), but never got a result on PG openCL.

I would like to know the powerconsumtion of the 520pci - perhaps my old server-PSUs can handle it to reactivate them ...

BTW: Buisness or hobby makes occasionally no difference… however sometimes I guess, I am a museum attendant. ;-)

The 38xx ATI series GPU ar DP capable, but they are not OpenCL capable. Basic rule of thumb: Lower than HD4xxx series cannot be used on PG since they do not have OpenCL support. Also, none of the AGP offerings from ATI have DP capability with OpenCl, so sieving is the only thing available to these cards barring some miraculous programming advance allowing single precision for LLR or Genefer. This latter point also applies to the AMD/ATI PCI bus option cards.



I would like to know the powerconsumtion of the 520pci - perhaps my old server-PSUs can handle it to reactivate them ...


The GT 520 card (regardless of bus) is only a 48 shader card. It will never be reasonable to run the world record units from Genefer on them. I would say that the 524288 units are about as big as is reasonable on those cards, and they will take quite along time with those. Given the costs and the modest difference in both the power consumption compared and overall price to the 96 shader options, you would be much better off looking at those models (GT430 for certain in PCI & GT530 available in PCI I believe...both at about 50W power consumption). The 96 shader cards can do the 524288 Genefer units reasonably, and are probably good enough for the 1048576 work as well.

You're right, genefer wr is not suitable for the low end cards. The GT520 have only about 13GFlops DP capability and my GT430 around 22 GFlops DP capability. Lastly I'm running the genefer 262144 on them with around 7 hours duration. Maybe it's time to check the runtime of the actual genefer 524288... ;)

BTW, the GT520 only have a power consumption around 30W. A while ago I'm running one (low profile PCIEx16) in a mini-PC with only a 220W power supply which was not replaceable. Because around 95W was used by the Phenom 9750 QC, the GT520 was the card with the most power which was able to run in this machine, without blowing the power supply. Genefer 262144 took around 9 hours to run on them, but this host was replaced, so I can't test on them anymore.

Thanks for information.

First I have to measure the real power consumption of the server boards under full load (i.e. 4x PPS sieve [CPU] because of 4x Opteron per board). Then I can compare the values with the data of the server-PSUs to get the overhead.
At the time, TYAN manufactured that boards, nobody thought about to equip them with CUDA-cards. So I have to study the datasheets to find the value of PCI max bus power load ... and equip if necessary the Condensers with passiv coolheads (radiator boxes).

A PCI-Card (or two) with Double Precision would be desirable. And perhaps I need bigger PSUs.

In meanwhile I have found rare and silent(!) CPU-Cooler. Without them a genefer task would lead in decibel to a "hearing fall" (dont know the english word for broken ears. ;)

ritch

Aware, I failed on different boards running two normal PCI cards simultaneously in one host. But I can't figure out, if this is limited by the PCI specification or by the boards I tested.

I only was able to run more than one PCIE cards (up to 3 PCIE-x1) one board or two cards with different slot types (AGP/PCIE or PCI/PCIE).

Hi Odi

My Serverboards have PCI-slots only. (My former question about AGP-Cuda/DP leads to other "old" hardware I would like to reactivate, too.)

My Serverboards (TYAN Thunder) you can find here: http://www.tyan.com/product_board_detail.aspx?pid=259 (it's an example of series 2 with the only different in ultra SCSI and colored Ram-Slots.)
The output of pure CPU-crunching for PG you can see here: http://www.primegrid.com/show_host_detail.php?hostid=97176
Imho still usable for non-GPU tasks.

As you wrote, it could be a problem of PCI-specification to use two cards - I think so, too. Perhaps with chance the TYAN is not conform with this standard, because it's no consumerware. Otherwise this boards are never build to use PCI-Slots without riser in practice because of 1HE-chassis. (poetic: there is a dark, small room and the end of life is the heat-overkill ... sorry, I'm a storywriter in RL and I rescue 5 of them out of a running datacenter-hell per hot-swapout. ;))
Well, I will try one PCI/CUDA/DP card. If it runs without problems it would be worth in my opinion to reactivate the whole cluster for PG-challenge-series. (but only with silent fans because I will need my ears in future, too. ;))

Back to the topic of this thread:
Pls have a look on this:
http://www.primegrid.com/workunit.php?wuid=265784772
A 680GTX may be "slow" but what's "slow" if you need to get a result without errors? All other wingmen with differend cards and mashines failed so far in upper task ... It is not important, why they failed, but that they failed.
The reason may be various, but at the end only results count.
So tell me pls, how "fast" a 680GTX is in genefer-WR-practice, while other waiste time and energy to reach the goal. 130h seems to be good with a result. ;))

ritch

The failures (and there's LOTS of them) have nothing to do with what type of card is being used, but rather how the card is being used.

You're running the GTX680 at stock speeds with the 300 driver. Probably 90% or more of the errors that you see would go away if the user switched to the 300 driver and ran at stock speeds.

Also, the errors don't waste as much energy as you think. The 295 driver errors take an hour to error out -- but the computer is idle, rather than crunching, during that hour.

Thats right, Michael, and everyone can read this warning while choosing genefer-tasks:

Overclocking GPUs is strongly discouraged. Nvidia Windows drivers 295.xx and 296.xx should not be used.

So there should be no problem. Not all Wingmen have an error after only one hour - some crunched for days before breakdown. (That's a waiste of time and energy, in my opinion. Well, ok ... who use redundant PSUs or ECC-Ram here, because there could be other reasons, too. i.e. power fluctuations ...)

All in all it's better to produce a result "slowly" than get an error "fast". Right?
Fact is: A gtx680 is stable to reach a result, if you consider the warning and tips. All, someone have to do, is to read and believe. ;)

[Shure I know: Overclockers have sporty ambitions and that's fine ... for short and prooven tasks. I will test OC with CW and PPS sieve, too ... no problem because of a possible waiste of 4-12 minutes - but shure I will never test OC with genefer-WR.]

btw: http://www.primegrid.com/workunit.php?wuid=265784772 The end of all: "Too much results". The wingmen shoot my correct result down. Will I ever get points or was it a waiste of time&energy, too? [15/15/5]

Absolutely. The sad thing is most of the errors are avoidable.

Something else to consider: Programs running on a GPU are not well protected from interference from other programs. It's VERY easy for another program to crash your CUDA program. Opening the wrong webpage that does the wrong thing with Flash could clobber a CUDA WU. That's particularly problematic if you're crunching on your regular computer as opposed to a dedicated cruncher. When WUs take a week to run, there's a lot of opportunity to blow up your WU. :(

(By comparison, the Windows/Linux/Mac operating systems are designed from the ground up to protect CPU programs from each other.)

Right, there could be a lot of reasons to fail - soft,- hardware and the "normal" use of the machine.

Interferences: Genefer-WR ran in background while I used the PC for normal daily videoediting. No problems at all. Perhaps because the 680 has a lot of ram and cores to handle it parallel. Perhaps this is the "power" of 680 in practice ...

Don't worry about your WU getting validated ,it will eventually.
I have been waiting a little bit longer,and I am expecting a new wingman
tomorrow,or the day after.
If you look at my WU,there are more than 15 wingmen,but it is still
continuing to be resent to new ones,until it finally gets validated.

http://www.primegrid.com/workunit.php?wuid=255765402

They wouldn't expect you to crunch for so long on one WU ,and get
no credits at the end of it.(people would stop doing them)

No need to worry about that. WUs that hit the 15 task limit (like this one and many others) automatically get bumped up to 50. They used to get bumped up to 35, but with all the silly errors we're seeing now, Rytis raised it to 50 instead.

None of the WUs have made it all the way to 50. Yet. :)

Ok, I see.
I saw the WU in the personal overview changing from pending to invalid. Now it's still "invalid" but the task was "upgraded" to 50/50/5.

Whats about an automatic in future: The PG-scheduler doesnt accept hosts for genefer with drivers older than 300.xxx. That could avoid a lot of errors and time/energy waiste and should not be a big act for the programmers to include that code. (Why we use computers? Because they can think for us, if we cant read warnings and facts. ;))

I dont see any results marked "invalid" in that WU. "Invalid" means the result is faulty and it won't get credit.

There's a result marked "Completed, can't validate". Is that the one you're referring to? "Can't validate" is not "Invalid". "Can't validate", for our purposes, is essentially the same as "Waiting for validation".

It's marked as "invalid" not "pending" in my personal task overview now. In the official overview its still "Completed, can't validate".

btw: Now I have a wingman without driver-problems ... so I hope this WU will not become a never ending story ;-))

What "personal task overview"? Is that one of the BOINC webserver pages (if yes, what's the URL?) or is it something else? I'm curious.

The topic of that list called invalid ("ungültig" in german). It's perhaps a "bug", but no real problem, because the task is official updated to 50/50/5 and not invalid at all. So it's no waiste and all I have to do now is to wait for the result of a clever Wingman. ;)

Not at all, Ronald. Normaly I stop Boinc for work and I dont use this machine for YT nor gaming. Its my only failed short genefer so far - perhaps its "bad luck" or its my fault because of overclocking experiments while this task was running. The "evironment" is imho correct incl. nevest 300.xxx driver. (No problem, all other short genefers and a long one too were completed.)

In case of the topic of this thread I'm interested in the OC-features of 680. Sieves run stable with slight OC. ATM I'm locking for a watercooling set because I "can't believe" that this highend card is "slower" than a 580. I've seen a report of "Mars II" (2x580) limited edition - as fast as expensive (1700€). *rolleyes* Would be interesting to compare pratice results between MARS, the science-commercial Nvideas (i.e. Tesla) and WC-OC 680 in case of price/speed and energy consumption ...
My first tests with 2x560ti in SLI have shown naturaly better results than a single 680 - of course there was never a daubt about it. But this "unfair" comparison didn't count with energy and price in a long term of crunching.
At least it could be a question of programming because in gaming and videoediting the 680 is still the fastest single-gpu-comsumercard for "low-budget" atm. With some tweaks and WC it should be able to reach 500.000 points per day on PG. (theoretical 400.000+ atm dependently of choosing the right task-combination. At least a compressor-cooling could reach more ... I've tested Cyrotec long time ago on Intel-4 CPUs, but that would be "extraterristical" on today's GPUs. ;) I didnt find an adaptorplate so far.)

All in all: If Nvidea produce intentionally "lacks" in consumerware to sell Teslas&Co then ATI will win the battle on BOINC. That would be unfortunate ...

btw: A comparison off apples and pears is allways a joke.
The Tesla C2075 costs about 2000€+ atm with 448 Cores and 6GB GDDR5. (a bit simular to 560ti without ECC)
That's as much investment as 4x680gtx with 4x1536 cores.
So guess wich system would be faster and "better" in practice (if you dont compare the power consumption of 4 vs. 1 cards). ;)
In crunching comparison the Tesla should complete a PPS sieve in less than 2,5 Minutes (because of 4x expensive) ... Is the Tesla C2075 realy be able to do so? 4x580 can realy crunch as fast and faster for shure and 4x680 can do it, too. (slightly OC)

Well, a comparison off apples and pears is allways a joke or leads to real results, in order to confirm the acceptance that something is more expensive than worth.

best regards,
ritch <- still a fan of 680 - as soon as I will find the hints and tweaks to get all out of this "lack" by deep-freezing the GPU and its RAM. ;) ATM on PPS sieve 11:14 per WU (untouched system). That's ok, but far away from the best and possibilities ...

Error 10 in Genefer means "MaxError Exceeded". BOINC doesn't understand that and thinks 10 has a different meaning. Ignore what it says about the environment missing error.

I see, Michael. How to solve this kind of "misunderstanding"? By using another "spelling" in the output - or is it a very rare exception error so there is no need to revise the code?
All I understand exactly: Something gone wrong in this task.

So, anyone have the new GTX 690 yet? That's a pair of 680's in 1 card right but running close to $1,000 a card.

So, anyone have the new GTX 670 yet?

Anandtech review (page 15) shows a tie to the gtx 580 at folding@home benchmarks. Not sure if this means identical performance with GeneferCuda (that would be a surprise, after 680 performance).

Actually my GTX460 was keeping up with my GTX680. My main problem is that my GTX460 is factory overclocked and for whatever reason won't let me actually get down to stock GTX460 speeds.

I see they're both on the same computer. What's interesting is that BOINC will gladly swap tasks between the two GPUs when the task gets restarted. For example, this is one of yours:

This one started running on your 680, with an estimated run time of 3:23, then finished on the 460 which had an estimated run time of 5:14. Those times (which are very accurate) are for running the entire work unit, not for the portion actually completed on each GPU. Your GTX 680 is therefore about 55% faster than your GTX 460 when running GeneferCUDA.

I generally consider a 460 to be 50% as fast as a 580, and the 680 (when running GeneferCUDA) to be 80% as fast as a 580, so combining those numbers, a 680 should be about 60% faster than a 460. These are just ballpark numbers.

Yeah, same PC, 460 is a PhysX card for when I'm gaming.

Ah that'd explain it then. I had two Genefer World Record tasks at the time that were keeping steady % complete matching or close so I assumed each one was just running on that single card.

I use EVGA Precision X to set the clocks, for whatever reason though even if I slide the sliders all the way down on the GTX460 it will actually set it to a slight overclock still, (less than the factory OC, but still above a stock 460) any ideas on how to get that GTX460 running at the normal GTX460 speeds? I've never had any issues with the 460s overclock, but always nice having a safety net there.

I haven't used Precision in a while, but this is the first I've heard of anyone not being able to lower clocks sufficiently.

I'd suggest trying it with MSI Afterburner to see if it will lower the clocks. Precision should be able to do this, but since these types of programs interact with the driver, variations in the driver version might have some glitches such as not down clocking. If neither Afterburner or Precision will down clock, then I'd try it with a different driver.

[Didn't know where else to put this, it seemed the most relevant place]

I've just read about the GTX770 actually being based around a GK104 chip, i.e. although it's got a different PCB and clock, and a couple of other (relatively minor when it comes to GFN) desirable things vs. a 6xx card; it's really a boosted 680. That's pathetic, the 470 and 570 were monsters, in a different league to the next card down, and only a slightly hobbled version of the flagship (single-GPU) model.

I think the annoying key difference at play in the GPU market is CUDA - Nvidia easily compete with ATI/AMD at a canter, because they have everything an ATI/AMD card has plus CUDA (and PhysX, but I don't think that's relevant to PG). Why would you buy an ATI/AMD card unless you're on a budget and the equivalent Nvidia card is a third more expensive? If running PG then the ATI/AMD card might not be a viable choice, unless you wanted it primarily for WWWW purposes. I don't mean to belittle Wieferich or Wall-Sun-Sun, I love them, but if I pay for a high-end card tomorrow, I would expect it to support all popular features, and also not feature a GPU which was mediocre even when it was launched a year ago. If I had the choice between a 570 and a 770, I'd pick the 570 every time.

We're stuck, ATI/AMD can't support CUDA, and Nvidia don't have to sell high-performing DP cards for non-business prices. So you could get a Titan for the money it would cost to get two 580s in SLI, plus probably the motherboard and RAM, or you could get a 780 for slightly less, which is much worse at DP than a 580. Or you could even spend a little less and go for a 770, which despite being the second-best single GPU model on offer for Nvidia, has a GPU which is a year and a half old and which they won't put in anything "proper", because it isn't very good.

Well, maybe someone should put forward an AMD GPU point of view. NVIDIA is a great choice but the argument against it is that once the GFN work units are gone there is only CUDA PPS Sieve and OpenGL apps left. The best AMD cards are better than NVIDIA at OpenGL, so in the long term AMD could be a good choice. The PPS Sieve is optimised for NVIDIA and CUDA. My HD7970 is running at 76% with PPS Sieve so there is plenty left to optimise. The Devs don't have a new AMD GPU so they can't optimise, but there is more performance to be had yet. Granted, GFN has years to run yet, but the run times will increase and you have to be happy with that or chose something else to run. I am running Wieferich and Factorial Sieve with my AMD GPU and loving it. A Wieferich prime would be an amazing find. Factorial Sieve is great in that it takes next to no CPU. NVIDIA is really hobbling its new cards DP performance, on purpose, to boost its specialised computational GPU range. NVIDIA has better drivers, but with a bit of effort the driver issues can be overcome on the AMD side. Choose carefully.

PS. I would sooner delete my post than start a GPU war.

Oh, don't get me wrong, I was slating Nvidia as being disappointing. It's not AMD's fault that they haven't got CUDA, I've always assumed it was a copyright/ownership issue. My point was that I think Nvidia have been really really disappointing considering what they could have released, and unfortunately for PG-crunching matters, they've not got CUDA so that excludes GFN (hence me posting in this thread). I was slating Nvidia more than AMD.

I should probably have simply said exactly that, I certainly wasn't trying to start a GPU war. I can completely see why the bigwigs at Nvidia are doing what they're doing, i.e. they'll price themselves out of the business market if they don't limit the DP capabilities of the GTX cards. It's just such a shame for everybody, aside from the handful of Nvidia execs.

I know Dave's last question is one addressing long-term policy, but as a pragmatic point, I'll offer this up anyway (in case anyone is in the market)... at least as of today, there are still a couple of places on Amazon to get a new 580. Of course, tomorrow they could be sold out. No doubt other sources are around, especially if you're willing to get a used one.

I'm fully on board with the "NVidia's consumer business policy is crap" sentiment. I dread the day when I have to replace one of my 570's (tosses salt over shoulder).

580: DP = 1/8 SP

680: DP = 1/24 SP

780/770: DP = 1/24 SP

Titan: DP = 1/3 SP



[add]
680, Titan


[add2]
With a GTX Titan you have to choose wisely whether you need SP or DP performance. If you tick the switch for SP in the driver settings, the DP performance will be lower and vice versa. Another point are the lowered clock frequencies after switching to DP. Normally a Titan works with 837 MHz (SP is factory default) and after switching to DP with 732 MHz.
Turbo boost 2.0 seems to be something useless, because the TB 2.0 is limited in TDP (250W) and core temperature (80°C). You can increase the values for core temperature to 95°C and the power target up to 106 percent = 265 Watt.

Don't we want to see how fast/slow a given card can do a GFN WU? Kepler will always thrash Fermi at idle because of its power saving, and of course the smaller fabrication process. I don't think that tells us anything about how fast they can complete one GFN WU.

Chip doesn't speak about the idle power... He said only, that no other work should be done on the GPU while running CUDA-Z.

...which is the point. Kepler will always use less power than Fermi when idle, but as I don't plan to spend loads of money on a card which is going to sit idle, I would like to know which one performs best. Should any graphics card win any awards for sitting there doing nothing, and saving a minute percent of power? They're not doing anything whilst idle, so they're wasting 100% of their power.

Test should be done when cards is idle!


I redid them at idle. I also included my OC stats as well, and yes I restarted CUDA-Z after changing the clocks.

Chip doesn't speak about the idle power...


He does:

Test should be done when cards is idle! I would like to see the results of the Kepler cards.



...which is the point. Kepler will always use less power than Fermi when idle, but as I don't plan to spend loads of money on a card which is going to sit idle, I would like to know which one performs best. Should any graphics card win any awards for sitting there doing nothing, and saving a minute percent of power? They're not doing anything whilst idle, so they're wasting 100% of their power.

I don't think they mean electrical power. I think they mean idle in order to get baseline I/O stats.

Well fair point, but why would that be relevant? Again, it doesn't matter what a graphics card is doing, when it isn't doing anything. We can all use GPU-Z and CUDA-Z to compare stats whilst performing tasks, but if a PCI-E card is doing nothing aside from causing you an electricity bill, then surely any comparison is a moot point?

Something which might possibly be of interest to the developers is the stderr output for this WU I just finished - I was trying to see how far I could overclock my 580 (partially for my own amusement, but also to see how the newer geneferCUDA builds handled errors):

So it ran for about 5 hours at 877MHz, and then I noticed it was stalling, and so reset my card to its factory default, when it completed. I think it should validate, I've had tasks error out like most people have, but I've never had a GFN complete but then fail validation.

So, bottom line is that the error recovery seems to be vastly improved. Also, this example might demonstrate that overclocking a GPU too much will actually make it slower, if it ever does complete; my previous completed GFN WU on the same card, clocked at 819MHz for the duration, completed in 8 hours 9 mins, whereas this took 8 hours 30 mins, because of the repeated 10 minute error recovery delays.

Yes, you're right, I did want to do a time on a par with a Titan, just to prove a point. Since we've gone to n=20 I think the fastest time I've done is 8:02, but that was about a year ago. I suppose I should go against my own advice and clock it at something like 840MHz. Please either wish me luck or call me stupid.

Thanks. Yes, it is, and I'm rather proud of the way it works now. It's actually better than I had hoped in that I never expected it to be able to recover successfully from overclocking errors. Nonetheless, I've seen many successful validations following recovery from maxErr errors.

Overclock by too much, however, and the program WILL give up. 6 errors in a row without making progress (i.e., reaching the next checkpoint) will cause the task to abort. There's also always the possibility of there being an error that isn't caught until the task eventually fails validation against the wingman.

There's still one error handling improvement I want to make when I get time. There's a certain set of circumstances where the program currently can't continue, even though in theory it's possible. Fortunately, it's not that common.

One thing I've noticed on my computer is that CUDA errors (not maxErr errors) seem to be a lot more common than they used to be, for whatever reason. Without the enhanced error recovery, I think more than 50% of my short GFN tasks would fail. I never used to get any errors. I don't know if it's a change in the drivers, updates to Windows, other software on my computer, or simply aging hardware. I'm fairly confident it's not Genefer because the guts of the program hasn't changed, and, in fact, the entire program was unchanged while the error rates were increasing.

My vote is the aging hardware. I recently (couple of months ago) had some errors crop up on my GTX 460s that were overclocked--cards that never had any errors before. Down clocked the memory and no more errors.

Might be interesting to test these possibilities once the challenges are over. Easy enough to down clock or install the older driver. I am doubtful about Windows updates, though they have a talent for finding ways to cause problems.

I think that must be the cause of my previous problems, which I falsely attributed to de-selecting GFN on the preferences page - at the time it seemed like too much of a coincidence, but what I didn't know about was the better error handling - I think it must have run for several hours and then encountered an error, and so stalled and tried to recover, but for whatever reason it couldn't. 877MHz is a ridiculous speed for a 580, again, the WU I linked to up there was half a test. I think it will be validated though; it was lucky I was at the PC and watching the progress. I'm having one more overclocking attempt now and running a GFN at 831MHz, and if it doesn't complete and validate I'll stop being childish and leave it at its factory default.

Edit: Owch, that task was one error away from being aborted, then...

I looked at the result in that task, and it looks ok. Bad residuals often (but not always) have a distinctive repeating pattern to them; your result does not.

Thanks for looking at it, hopefully it will validate. Below is the result of me trying out 831MHz, I wouldn't have bothered mentioning it except for the fact that it decided to use Shift=7 - I can see from the benchmarks that there is no difference between =7 and =8:

I could run another WU at the same speed and force shift=8, but I think that will prove very little, i.e. it might be a few seconds faster or slower, but it doesn't really matter...

Anyway, this is the first time I've actually bothered testing anything properly, and I thought I'd hate it, but quite the opposite. I've learned a few things.

Thanks for looking at it, hopefully it will validate. Below is the result of me trying out 831MHz, I wouldn't have bothered mentioning it except for the fact that it decided to use Shift=7 - I can see from the benchmarks that there is no difference between =7 and =8:

Stderr output

~snip~

SHIFT=7 187236^1048576+1 Time: 1.61 ms/mul. Err: 2.54e-002 5528501 digits
SHIFT=8 187236^1048576+1 Time: 1.61 ms/mul. Err: 2.54e-002 5528501 digits


It would have chosen whichever is faster regardless of how small the difference was. It's likely the difference was less than 10 microseconds per iteration and therefore both timings showed as 1.61.

I could run another WU at the same speed and force shift=8


If the WU is still running, it's very easy to change the block factor of the task (it's safe to do so in the middle.):

* Change the block factor in the PrimeGrid preferences on the website.
* Pause the task.
* Hit "Update" on your BOINC client so that it reads the new preferences from the server.
* Resume the task.

The task will now resume running with whatever block factor you set in the preferences.

It was actually completed when I posted; but I didn't know it was safe to change the block settings during a run. I think I'll leave them alone anyway, if it's chosen the fastest one then there's nothing to worry about... I was just surprised to see that it chose 7 rather than 8, that's basically it. Cheers for the advice.

I was really enthused about the longer runs and talked it up. Then all the Genfer Wu's were lost due to an error all 874306.71 sec of run. yes I was running 2 Nvidias 680's. Could have used the time elsewhere receiving points. Now if the 17's finish even with the extra credit I still am on the losing end.
