One of my Linux-hosts:

can not get any genefer tasks for GPU (NVIDIA GTX 275).
Tried both short and WR-tasks.

BOINC can see the GPU, and it downloads and runs cudaPPSsieve fine:

Any ideas?

Do you have any PG tasks suspended? BOINC will not send any units to a host that has any of that project suspended.

No suspended tasks, no other projects. Only 4 Genefer CPU tasks running.
And it did load PPSSieve cuda units fine, when I tested those.

A few, yes.

There's only a few difference between the setup for PPS Sieve and GFN, so if one works and the other doesn't it has to be one of those.

ALL of the diferences:

PPS-Sieve:

<min_nvidia_compcap> 100 </min_nvidia_compcap>
<min_cuda_version> 2003 </min_cuda_version>
<min_gpu_ram_mb> 180 </min_gpu_ram_mb>
<gpu_ram_used_mb> 180 </gpu_ram_used_mb>


GFN:

<min_nvidia_compcap> 103 </min_nvidia_compcap>
<min_cuda_version> 3002 </min_cuda_version>
<min_gpu_ram_mb> 384 </min_gpu_ram_mb>
<gpu_ram_used_mb> 384 </gpu_ram_used_mb>


The GFN task requires CC 1.3 while PPS sieve only requires 1.0. That's not your problem because the 275 is at least 1.3.

The GFN task requires more video memory than PPS-Sieve, but that shouldn't be a problem on a 275 unless some other program is using a lot of video memory. What else is running on this box? Have you tried rebooting?

Finally, PPS-Sieve is older and requires CUDA 2.3 while GFN requires 3.2. I suspect that's the problem. Since CUDA is built into the video drivers, it's possible that updating the drivers will fix the problem.

Nothing else is running, this box is only for Primegrid.
And I have tried rebooting. Boinc shows:

pe 03.01.2014 21:21:40 CUDA: NVIDIA GPU 0: GeForce GTX 275 (driver version unknown, CUDA version 6.0, compute capability 1.3, 895MB, 755MB available, 1011 GFLOPS peak)
pe 03.01.2014 21:21:40 OpenCL: NVIDIA GPU 0: GeForce GTX 275 (driver version 331.20, device version OpenCL 1.0 CUDA, 895MB, 755MB available, 1011 GFLOPS peak)

I will try other versions of the video drivers.
