Dear All,

If you've been following other threads on the forums, you'll know that the Windows versions of the science application have recently been updated. There are now two versions, 849 (CUDA 6.5) and 918 (CUDA 8.0), which will be assigned to hosts as follows:

* 849
- Windows XP (32 or 64 bit) and any GPU >= sm 3.0
- Any 64bit Windows with a Kepler 3.0 device

* 918
- Any 64bit Windows, Vista or later with any GPU > sm 3.0 and driver >= 370.0

The peculiar exception for sm 3.0 devices is due to a compiler problem with CUDA 80 that affects only that hardware version. When that's fixed, hosts with a non-XP Windows will get 918.

If you see any behaviour that deviates from this, please report it here.

If you think you should be getting work, but aren't please check that your system complies with the above, in particular the driver revision and that the OS is 64 bit.

I've checked this on one of my Windows XP x64 hosts, and it has received the v9.18 (CUDA8.0) client.

Host details
EDIT: you may see this host as a Windows 10 PC, as right now I'm updating the "spare" Windows 10 OS on my hosts. But it had received the CUDA8.0 client before I begin to work with this host (i.e. under Windows XP x64, GTX 980 Ti, driver v358.50).

I have received two 9.18 CUDA 8.0 tasks on my xp computer, they errored out:

The computer has driver 355.82 CUDA 7.5.

I have 2 GTX460 cards (Hosts 317733 & 208443) that have been unable to get work since the changes over the weekend.
Both are running Driver ver. 378.92. According to GPU-Z these cards are sm 5.0.

The project will not send work saying no tasks available.

Other computers running GTX750Ti & GTX1050Ti are reciving work without any problems.

I'm getting the same error of not receiving tasks for a GTX 570 with 381.65 Windows 8.1 However no problems with my other cards: GTX 770, and GTX 660TI.

Since the 570 and 460 cards are Fermi based, I am guessing that they might not be supported anymore. But that is speculation on my part as I am not an advanced computer user.

Based on the recent information that GPUGRID will run on Windows XP for one more year, I tried to continue crunching on my XP machine (driver 361.75).
However, BOINC says

18/04/2017 07:14:02 | GPUGRID | No tasks are available for Long runs (8-12 hours on fastest card)

although the Project Status Page shows 300+ unsent tasks.

What can I do to get the thing work?

I tried again late afternoon, and could download new tasks :-)

I confirm too, that my Windows XP x64 hosts have received the 8.49 app, and it's working.

Suspending, with the 918 app, is not working correctly! It sometimes takes ~20+ seconds to see the app respond to a suspend request. It should be < 3 seconds!

Also, you mention "The peculiar exception for sm 3.0 devices is due to a compiler problem with CUDA 80" ....... so:
- Who is responsible for fixing that (you, or NVIDIA?)
- What steps are being taken to get it fixed (have you contacted the right people?)

I have the same issue on my windows 10 computer, running GTX980ti cards.

Suspending has taken up to 5min on Win8.1.
Resume/suspend an issue where (15) WU error upon resume on same or different GPU.
WU need to run without interruption to get a proper validation.

Message 47066 - Posted: 22 Apr 2017 | 5:33:09 UTC - in response to Message 47049.

I upgraded both of my PCs to the 381.65 driver, and I am no longer getting work. It is a bit unclear to me whether I should be getting work. From what I understand, my 460 and 580 are fermi based, but from the announcement, I am lead to believe that Fermi is still supported. I do realize that there are others using similar cards and that they are not receiving work, either, so I am guessing that these cards are now no longer supported.

Matt, is it official that Fermi is no longer supported for gpugrid?

Thanks.

Yes.
Fermi (GTX 4xx & GTX 5xx series) is CC2.0 and CC2.1 which is below the minimum required CC3.0 therefore they are no longer supported for GPUGrid.
Due to some undisclosed "compiler problems" the the lesser Kepler based cards (CC3.0, GTX 660Ti) will fail all tasks.
See the compute capability (CC, also known as Shader Model (SM)) table on Wikipedia.
