ATI/AMD GPUs must support OpenCL and have double precision floating point hardware.

I'll put up a list here as soon as I do some research on which cards support DP (or someone provides me with that information.)

This list may be incomplete (I don't keep up with AMD/ATI cards), but might be a good starting place. Columms highlighted in green show the double precision capable cards.

Is OpenCL 1.2 a requirement?

My HD4850 is DP capable and supports OpenCL 1.0 but cannot run this application, it just errors out after around 10 seconds

Here's a list of Double Precision FP ATI/AMD cards capable of at least OpenCL 1.1 or higher and should run GFN. Unfortunately the HD 4xxx series and older will not work.

HD 5830
HD 5850
HD 5870
HD 5970

HD 6930
HD 6950
HD 6970
HD 6990

HD 7730
HD 7750
HD 7770
HD 7790
HD 7850
HD 7870
HD 7950
HD 7970
HD 7990

I'm not sure about which mobile cards will work or not at this time, but the high end ones probably will.

OpenCL 1.0 and DP is all that's required, but AMD may have dropped OpenCL support for the 4800 series cards in recent drivers. There was some discussion of this in the development thread that you might want to read:

I didn't think OpenCL 1.0 would work with the new GFN app. I guess I stand corrected. Anyway, yes, ATI/AMD's OpenCL 1.0 support for HD 48xx was dropped from their drivers last year. I think 12.4 was the last driver to support them but I'm not positive. One of the 11.x drivers should work then (avoid 11.6-11.8... OpenCL bugs).

In addition to using an 11.x driver you will probably need to install AMD APP SDK v2.4 as well. You should do a clean install of both by first uninstalling any later versions with the Driver Sweeper app (Google for download) and start from scratch.

Also I found some more tech info on ATI/AMD cards and drivers + links for older drivers and AMD APP SDK v2.4:

http://www.gpu-tech.org/content.php/151-Catalyst-11-3-is-out-and-makes-OpenCL-mandatory-AMD-APP-SDK-now-at-version-2-4

http://www.hal6000.com/seti/boinc_ati_gpu_cheat_sheet.htm

Hope this helps out some people.

Will I be able to somehow see it when I use a non-DP GPU?

Or is it then just producing "garbage" which does not validate against other results?

I am not sure if my APU and my GPU is DP capable as wikipedia is not very clear on that.

The first generation of APU (Llano), whose CPU number format is A?-3??? doesn't support DP (if someone wants to try just to be sure, go ahead).

The second generation (Trinity), whose CPU number format is A?-5??? (in desktop) and A?-4??? (in notebooks) supports DP, but I'm not sure on this one. Again, some confirmation is welcome.

The third generation (Richland), whose CPU number format is A?-6??? (in desktop) and A?-4??? (in notebooks) supports DP. The GPU of Trinity and Richland are in the same level, so if one supports it, the other will too, but, again some confirmation is welcome.

To summarize (subject to confirmation, please report), one can run it in APU if it's A?-(>3)???.

On the low power range, the first generation (Brazos), doesn't support DP.

The second generation (Kabini), however, should support DP, but this one I really don't know. If anyone has this APU, please let us know if you can run GeneferOCL.


On the mobile GPU front, 7730M or higher should run it, and then all of the next generation (8???M) too.

8730 or higher also runs GeneferOCL.

But if anyone is actually sucessful (or unsucessful) in running GeneferOCL on their particular card/APU, please say here. An exaustive list would be very helpful.

Oh, and while you are at it, the runtimes for the short tasks (even if they are growing, a indication of the size is already good) would be very useful information. I think the majority (to not say all) of mobile APU's, for instance, won't be able to complete the short tasks in time even running 24/7.

After a little research it looks like only APUs with the GCN architecture has DP capable GPU side.

I have an AMD Radeon HD 7670M, and I have computation errors running genefer (atiGFN). Is there some trouble or this card don't support any DP?

Your GPU does NOT have DP. Only HD 77xxM or higher does.

I have an idea - would " I can run Milkyway-OCL which also need DP on this GPU/APU" be an indicator that I can also run genefer-OCL?
Their runtimes are much shorter and could be used as an indicator, and in their forums is a long list of supported GPUs...

Maybe you can also ask them for information ^.^

http://www.primegrid.com/result.php?resultid=482102691

I don't know why it doesn't run but in any case the HD 4000 series doesn't include local memory. Because a requirement of OpenCL is local memory support it is emulated but is very slow. Genefer makes intensive use of local memory. Then I don't think that Genefer OpenCL running on a 4xxx would perform better than the CPU version.

According to Wikipedia, the HD 6870 doesn't have double precision, so it can't be used.

Message 81993 - Posted: 3 Jan 2015 | 7:21:02 UTC

What is the likelyhood of the AMD R9 285 being supported in the near future?

Per the specs page here http://xfxforce.com/en-us/products/amd-radeon-r9-series/amd-radeon-r9-285-double-dissipation-edition-r9-285a-cdfc

It says "Double Precision Floating Point"-
Which is disappointing there's no output figure-
-and a relief because things moved very fast and before I knew it, I had a new system, built around this GPU & I'd be upset if there was no computing potential

As I understand, its the first of AMD's newest architecture revision. Here's to hoping its a bright one.

I've been struck by a Nvidia and an Intel recall the last two time I went on the edge

See http://en.wikipedia.org/wiki/List_of_AMD_graphics_processing_units for figures.

"Tonga is configured for 1/16 rate double precision performance, 1/4 the rate of the more powerful Tahiti".

AMD Radeon R9 285 Double Dissipation Edition: 3.34 TFLOPS Single Precision => 208 GFLOPS Double Precision.
AMD Radeon R9 280 Double Dissipation Edition: 3.34 TFLOPS Single Precision => 835 GFLOPS Double Precision.

How significant is that in practice?
The "Fastest GPUs" page here on Primegrid puts the Tahiti cards near the top, however, it says the R9 280x, the most likely Tahiti card I could get, is only twice as fast as the 7850/7870 series (Pitcairn)

This is a significant point, because, according to the page you linked, the R9 285 (Tonga) should faster than the Pitcairn.

If Tahiti is only about twice as fast, I don't think I'll worry too much about it. I will have to wait for support to be added however
Tahiti been around a long time too. I'd be interested to know either why its performance doesn't match the specs or why the Pitcairn card does so well for its low Double Precision
PPS SV says more or less the same thing & I'm assuming its not DP

I used a Radeon R9 270 and built a table with the timings of my wingmen.
GFPS-Short:
Radeon R9 280 (Tahiti): 6:30 hours.
Radeon R9 270 (CuraƧao ~ Pitcairn): 11 hours.

The R9 270 and the R9 285 run at about the same clock rate and for both DP performance is 1/16 SP performance.
But the R9 285 has 1792 units and the R9 270 has 1280.
Radeon R9 285 (Tonga): 9/10 hours is a reasonable estimate.

I'd be interested to know either why its performance doesn't match the specs or why the Pitcairn card does so well for its low Double Precision PPS SV says more or less the same thing & I'm assuming its not DP

The program also reads and writes a large amount of data then memory bandwidth should be taken into account.

Today I tried to participate using my R9 290X (MSI Lightning) but no WUs were delivered to my system (Win7/x64, i5-2500K, 8 GB RAM, BOINC 7.4.36 x64, latest ATI driver), so I exactly cloned the following information:

Thanks a lot,

now the Radeon R 290X starts Crunshing GNF-WUs.

This morning, I finally got a WU.

The runtime estimate is almost 153 hrs - is this normal for a "Genefer (World Record) 2.10" WU or isn't it rather possible that this is quite overestimated?
It sems quite long to me, because this type of WU is part of your upcoming challenge and would take 6 days to complete while the challenge itself lasts only for 8 days meaning that I can process exactly a single WU of this type during that whole challenge. ;-)

And one more question:
The website preference settings of this sub project state that "some ATI/AMD GPUs may require installation of the ATI Stream SDK". Is that required for a 290X card, does it speed up the computation?

Michael.

This sounds pretty accurate.

With drawing up the challenge schedule I was aware that many people will only be able to complete 1 WR unit. That however is to me part of the challenge. Are you confident in your machine that you go for the big score with 1 WR unit and filling the left over time up with "short" units, with the risk that your big scoring unit gets invalidated for some reason? Or are you going to bet on completing as many short tasks as you can, missing out on the significant bonus credit WR's give, but minimizing the damage if one WU gets invalidated... :)

Well, I will try the long one - so far I had no problems with my 290X.

Still, what about the AMD SDK requirement? What is it good for?
I mean, the WUs download and start without complaints - that's clear - but would there be any benefit having the SDK installed?

Most of us are in the same boat, only being able to complete 1 WR unit in the 8 day time frame. The very fastest GPUs (e.g. NV Titan) might cram 2 in. Your 290X should do well. BOINC "estimate to complete" times are notoriously bad. Just let it run for a few-%, note the elapsed time, and extrapolate.

NOTE: if you're still running that WR unit, you won't get challenge credit for it, since it was downloaded before the start (18:00 UTC Thursday Apr 23). Assuming it validates, you will still get normal BOINC credit.

Well, it seems that I was right. Based on the current progress bar indication and the re-calculation of the remaining WU duration, that "long" WU should finish in significantly less time than half of the original estimate on my card (approx. 60 hrs per WU). So, it should be possible to work up 2 WUs during the challenge duration...

Of course, maybe even the progress bar indication is not reliable. ;-)
And also, it might be that this WU won't be validated at all as my card is factory-overclocked (it is the MSI R9 290X LIGHTNING, which I fancy a lot because of its excellent and comparably silent cooling system).
However, so far I have not experienced any faulty WUs with other DC projects and to my experience, PrimeGrid quite certainly is not the most GPU hardware challenging DC project out there in the wild as judged by GPU temperature.

It would actually have been nice, if - at least during an active challenge - the returned WUs could be validated. For several days, this one is sitting there with no other copy handed out for validation.
Thanks.

Count yourself lucky that this is during a challenge. At some point, I saw a WU, I think it was Sophie Germain, on the Subproject status page marked as the oldest remaining WU. It wasn't actively being crunched by anybody, and it had been sitting, unsent, waiting for validation, for several weeks. Somebody will get your WU eventually, and those numbers aren't going anywhere.
