Message 28633 - Posted: 1 Dec 2010 | 16:31:28 UTC

PrimeGrid is excited to finally announce the official release of the tpsieve application in the PPS (Sieve) project. Linux, Mac, and Windows platforms for 32/64 bit are all supported as well as CUDA and OpenCL (ATI). Only Mac OpenCL is NOT currently available. Also, OpenCL requires an app_info file to run due to a scheduling request issue. However, we hope to have that problem resolved before the next Challenge (18-21 December). NOTE: Windows GPU users should update to .NET Framework 3.5.

tpsieve, based on Geoff Reynolds' original code, is a revolution to k*2^n+1/-1 sieving. Thanks in large part to Ken Brazier's updates and modifications to include simultaneous +1/-1 dat-less sieving as well as his ports to the GPU, tpsieve has changed the landscape of sieving and is now providing incredible support to the prime finding community.

Thank you Ken!!!

How much memory does a GPU need to work with this. I have an nVidia Quatro NVS 135M, but it only has 128 MB.

Pardon the newb question, and I have tried to do a fair amount of reading on this in the message boards, but does this mean that sieving on this particular problem no longer requires a manual setup? Since coming to PG I've been a little confused on the whole CUDA implementation situation as I initially came to PG under the assumption that using my GPU for the project would be a relatively seamless endeavor (ie. check off some settings in BOINC etc).

Don't get me wrong, I (now) understand that CUDA support isn't exactly a cut and dry situation and requires a good amount of manual labor on PG and its community...I'm just trying to come to grips with how PG is using it.

Was the manual sieving that was/is going on just an effort to get it running well before heading full on into seamless integration?

And stop sniggering at the back...I can hear you.

Arrhythmia, I didn't have to do any configuration to get CUDA working. I only enabled PPS sieving in my PrimeGrid Preferences under my account settings. If your video card is detected by BOINC it should automatically download and run CUDA tasks.

A simplistic potted history of PPS Sieving...

Most sieves start with a manual effort by a select few (Lennart!) to get things started.
In the case of PPS Sieving it then moved to a situation where it was offered to BOINC users but only after applying directly to an admin to allow them. The reason being the size of the sieve file. They wanted to keep a firm grip on the number of users that needed to download the beast.

Next it was opened up to all BOINC users.

Then recently (and beyond all expectations) a GPU version was created for CUDA and OpenCL (that doesn't use a sieve file) by the Ken the wizard. The only complication was that BOINC wasn't allowing NVIDIA Fermi and ATI GPUs to get WUs. That now seems to be resolved for Fermi but not for ATi. PrimeGrid is hoping that will also get resolved before the upcoming PPS Sieve challenge.

The above is only how I see it and I'm sure is not 100% accurate.

Pete.

I'm running successful PPS (sieve) on 3 CUDA cards, but get this message on an ATI 5770 card:

12/2/2010 1:01:50 PM PrimeGrid Message from server: _("No work available for the applications you have selected. Please check your project preferences on the web site.")


On application page can read that exists an (ati13ati) application ( is this the openCL application? ) ... and don't understand what do you mean with:

Also, OpenCL requires an app_info file to run due to a scheduling request issue.


Need I an app_info file ? If yes, where can I get it ?

Regards,
Ale

Much appreciated for the clarification TB, now I understand why I was getting the message that there was no work for my GPU when I originally tried to sieve as it's a GTX460 and, thus, a Fermi card. That's what was causing the bulk of my confusion on CUDA support...I didn't realize there were some issues with Fermi. No doubt that was explained somewhere, I just missed it trawling through the posts.

For anyone that uses the Lunatics app for seti you should be fairly familiar with the ATI setup and app_info. This was a fairly simple install.

One question though. Will this sieve be adapted to the other projects?

Good crunch!


I think u should change that to:
"Good Luck with the square-eyes after wading thru all 300-odd posts in that thread!!"

Having done just that myself, I can truly appreciate the incredible effort made by Ken & all the testers to make this happen. - Hats-off to them!

My "HotBox" boasts the following:-

Processor: 8 GenuineIntel Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz [Family 6 Model 26 Stepping 5]
OS: Microsoft Windows 7: x64 Edition, (06.01.7600.00)
NVIDIA GPU 0: GeForce 9800 GT (driver version unknown, CUDA version 3020, compute capability 1.1, 494MB, 308 GFLOPS peak)
ATI GPU 0: ATI Radeon HD 4700/4800 (RV740/RV770) (CAL version 1.4.880, 512MB, 1000 GFLOPS peak)

The mere fact that these 2 GPUs are both crunching side-by-side with all latest drivers is a minor-miracle in itself... - more on that Here:-
http://boinc.berkeley.edu/dev/forum_thread.php?id=5576&nowrap=true#34536

..But I would Dearly Love them both to be working together on the next Challenge! - (ATi is currently working on DNetC & Collatz)

So my Humble Request would be for Somebody.. (Ken??) to condense all that hard work down into a single downloadable Package (.exe + App_Info + Idiot-Guide) that folks like us could use to get our ATi-monsters crunching as soon as possible without drowning in all the finer technical details!

Of course First-Prize would be everything working automatically without the need for app_info at all.. so I would be delighted if this request were to be rendered obsolete in that way!
- Any news on how long that is likely to take??

To get the first prize I need a sched_request_www.primegrid.com.xml file from anyone who has an ATI card but cannot get any work without app_info file. If you wish to send the file (admin@primegrid.com), please make sure that you do not have app_info installed and that the last scheduler request actually asked for ATI GPU work. The file can be found in BOINC data directory.

To get the first prize I need a sched_request_www.primegrid.com.xml file from anyone who has an ATI card but cannot get any work without app_info file. If you wish to send the file (admin@primegrid.com), please make sure that you do not have app_info installed and that the last scheduler request actually asked for ATI GPU work. The file can be found in BOINC data directory.

One question though. Will this sieve be adapted to the other projects?

In general, no. The other sieves at PG do not have enough k's in them to take advantage of ppsieve/tpsieve. The PPS (Sieve) has 4998 sequences (k's). In comparison, 321 (Sieve) has one k, TRP (Sieve) has 63 k's, and PSP (Sieve) has 11 k's (currently paused).

It might be plausible to port the Cullen/Woodall (Sieve) to GPU but that remains in development. Success is still unknown with this endeavor. :)

It works without app_inf file

But i think the 0.89% cpu usage is to high i have use the app_inf with cpu usage 0.2 - 0.5% and it works. The finish time was the same.

But I checked the CPU consumption in Task Manager and it was between around 5-20% CPU time. It isnĀ“t that bad...

It works after a project reset. The CPU usage with 0.87% seems a little bit high or its a design problem, will check it later with a final result if there is a difference between the app_info file settings.

After I checked, the original driver did not have the SDK, so I updated the driver and now they complete fine.

O happy day! Great to see the 2 GPUs crunching together! Both taking around 40min per task - as opposed to around 15hr per CPU! Bring on the Challenge!
- and Ati runs around 8degC cooler than with DNetC!

Thanks to all who made this possible.

It works after a project reset. The CPU usage with 0.87% seems a little bit high or its a design problem, will check it later with a final result if there is a difference between the app_info file settings.



Now the CPU Usage is down to 0.45%

I know what is yor Problem The ATI GPU that you use is not supportet by ATI Stream i have the same with 2xATI 2600XT and with 1 ATI 3850

More info can you find on this Side ther are an List for all Supportet Cards

I think u should change that to:
"Good Luck with the square-eyes after wading thru all 300-odd posts in that thread!!"

Having done just that myself, I can truly appreciate the incredible effort made by Ken & all the testers to make this happen. - Hats-off to them!

My "HotBox" boasts the following:-

Processor: 8 GenuineIntel Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz [Family 6 Model 26 Stepping 5]
OS: Microsoft Windows 7: x64 Edition, (06.01.7600.00)
NVIDIA GPU 0: GeForce 9800 GT (driver version unknown, CUDA version 3020, compute capability 1.1, 494MB, 308 GFLOPS peak)
ATI GPU 0: ATI Radeon HD 4700/4800 (RV740/RV770) (CAL version 1.4.880, 512MB, 1000 GFLOPS peak)

The mere fact that these 2 GPUs are both crunching side-by-side with all latest drivers is a minor-miracle in itself... - more on that Here:-
http://boinc.berkeley.edu/dev/forum_thread.php?id=5576&nowrap=true#34536

..But I would Dearly Love them both to be working together on the next Challenge! - (ATi is currently working on DNetC & Collatz)

So my Humble Request would be for Somebody.. (Ken??) to condense all that hard work down into a single downloadable Package (.exe + App_Info + Idiot-Guide) that folks like us could use to get our ATi-monsters crunching as soon as possible without drowning in all the finer technical details!

Of course First-Prize would be everything working automatically without the need for app_info at all.. so I would be delighted if this request were to be rendered obsolete in that way!
- Any news on how long that is likely to take??


Support immense..
specialy: a single downloadable Package (.exe + App_Info + Idiot-Guide)
and hopefully + Idiot-Guide

Many thanks to all the Programmers !!!
I will 'dry-run' all my work now..and try another 'clean' install of it..

Happy X-mas to all of you from snowcovered Switzerland

...The other sieves at PG do not have enough k's in them to take advantage of ppsieve/tpsieve. The PPS (Sieve) has 4998 sequences (k's). In comparison, 321 (Sieve) has one k, TRP (Sieve) has 63 k's, and PSP (Sieve) has 11 k's (currently paused).

It might be plausible to port the Cullen/Woodall (Sieve) to GPU but that remains in development. Success is still unknown with this endeavor. :)


I asume it is safe to push 321 Sieve on 64-bit CPUs and leave PPS Sieve for GPUs only.

Was is considered to issue PPS Sieve only for GPUs? I believe we have enough computing power using GPUs on this subproject and CPU would be better on other subprojects or PSA.

This might also help running both CPU and GPU without app_info
(I'm aware of work-around not to select PPS Sieve if you actually want to run PPS Sieve on GPU...which might look strange)

What is causing that abort????

After some more research, I'm becoming convinced this is another side-effect of that "Duration_Correction_Factor" bug in the Boinc Manager... More Here:-
http://www.primegrid.com/forum_thread.php?id=2668&nowrap=true#28765

My Estimated "Time To Completion" for ATi PPS tasks in Boinc Manager is 7min55sec while that for Cuda PPS tasks is 41min05sec.

Yet they both take more than 42min to complete.. So is there some code somewhere that aborts a task when it takes more than 5 times its estimated run-time??

How many of those experiencing problems are running multiple GPUs??

Did my first ATi task perhaps run OK because that "Fudge_Factor" had not yet been skewed by a previous ATi PPS task?

I manually fixed the duration correction factor, so that boinc now thinks that the wu will be done in 50 mins (44 really), so I tought: it should work now. In fact, it doesn't still work: maximum time elapsed error (-177) after 36 mins, so within the time thought at the beginning.
So I think that you have to correct flops required counter in the wu or the app will NEVER work without app_info.xml... It's NOT a problem of duration correction factor!

By now I had already changed estimates by 10 times; it doesn't seem to help. So I changed some other settings server-side instead; let's see if it helps now.

Well, it is now fixed for a 4650 I have on Win7 64-bit. However, on a 4670 I have in Vista 64-bit I still get the error. The runtime, however, did change. Before, the error occurred about two-thirds through (about 4800 secs), but now it almost completes (error at 7200 secs...would finish in 7500). Also, my other 4670 on a 32-bit XP box completes with no problems.

Just an idea.

Those crunchers having tasks that abort after a certain time with "Maximum time exceeded" error: Do you use an app_info file?

If so, you could have a wrong <flops> value in your info-file.

no, the problem arises only when NOT using app_info.
In fact, I suggested to Rytis to change the <flops> value server side, not the <duration_correction_factor>, because modifying the latter doesn't do anything to prevent auto-aborting wu as he just discovered

In fact, I suggested to Rytis to change the <flops> value server side, not the <duration_correction_factor>, because modifying the latter doesn't do anything to prevent auto-aborting wu as he just discovered

So the problem seems to be a setting on the server.
IMO Rytis should increase the rsc_fpops_bound value, that he is sending with the WU's.

Your log contains the message: "Maximum elapsed time exceeded".
I think <flops>1.0e11</flops> is to high for your ION-gpu and you should lower this value to <flops>1.0e9</flops> or <flops>1.0e8</flops>.

My CPU usage displays now 0.73 instead 0.40 :/

Which doesn't really mean anything - it is not a real CPU usage.

I'm reposting from the other thread since this IS a problem and should be simple to fix: Tthe ATI app is asking for .52 CPU/WU. That forces dual GPU boxes to waste a CPU core. Using an appropriate app_info.xml can bring the asked for CPU reservation down to .05 with no slowdown. Could you please adjust the default app to ask for less CPU so we can eliminate the need for the app_info.xml? A CPU value of .05-.17 would be nice.

We really can't, because BOINC's stupid handling of task duration estimates kills tasks on some machines with a lower setting. I will try to lower the estimate very slightly to make it fit below 0.50/WU, but I won't do that before the challenge.

OK, just added an app_info.xml to all the machines as a workaround. Don't quite understand why it works fine with the app_info and can't be done as the default. I wasn't seeing task duration estimate problems either with or without. Maybe with VERY, VERY slow GPUs? The CUDA app doesn't seem to have the same problem.

An app_info overrides some server-side settings and the cuda app have the same problem.

Interesting, all 7 of my CUDA clients request between .05 and .09 CPU with no app_info and all 10 of the ATI clients request > .5 CPU unless there's an app_info to override it.

Hmm. After some searching i believe Vato found the answer for this problem. He adapted my app_info from Cuda to OpenCL and i asked him, why he reserving 1 cpu-core for the gpu-app with <avg_ncpus>1.000000</avg_ncpus> and <max_ncpus>1.000000</max_ncpus>:

I'm reserving 1 CPU because that's the amount that the ATI OpenCL app uses on my platform. I'd quite happily reduce it if the app wasn't so CPU hungry, but it just makes the other CPU WUs thrash with each other. Sounds like there's a busy-wait in there somewhere, but I'm not smart enough to delve deeper.


There are two possibilities. Either the app uses more cpu resources as usual for an OpenCL-app or not all calculation steps could be implemented by OpenCL on the ATI-gpu. I don't know it.

I haven't run my CPU's at all before or during the Challenge here at PG anyway. I have about 74 Cores I could run but the output from them would only amount to what 1 GTX 460 would put out so it's not worth it to me especially when the GPU needs some CPU to not slow them down.

There are two possibilities for why Vato needs a full core. In the first case, you are correct: The initialization of the calculation couldn't be performed on OpenCL. There seemed to be something wrong with AMD's compiler. I've had problems with unstable versions of GCC on the same steps. So more is done on the CPU.

The other possibility is that Vato may be using old Catalyst drivers with the OpenCL SDK, instead of using newer APP drivers. Some very old Catalyst drivers seem to busy-wait instead of sleep-waiting.

I'm using 10.10 Catalyst with 2.2 SDK - which afaik is still a good combo under linux x86_64 (unless 2.3 SDK has come out without me spotting it) - no APP equivalent for linux yet.
I only have an HD4670, so it's not like I'm racing away with the CPU having to keep up.
The actual WU runtimes seem to be appropriate for this hardware - just the CPU usage seems a little high.
