short question about nvidia GPU / linux crunching
5 Feb 2017 23:36:52 UTC
Topic 205220
(moderation:
Right now I think the current GPU-linux requirements are:
- OpenCL 1.1 capable graphics card (this means GeForce 4xx and above)
- minimum 1 gig of memory on the graphics card
- 64 bit linux
Can someone please confirm this or correct me?
Btw: what AMD card is the minimum to meet this requirements? Radeon HD 5xxx?
Thanks,
Stephan
PS: This puts two of my crunchers out of the race. Sad, but ...

PPS: Is it possible to get CUDA workunits again? Or OpenCL 1.0

The answers are, (i) Yes (I believe but could be wrong), (ii) Yes but ~0.75GB for the beta test app, (iii) Yes (I believe), (iv) Why don't you check here.
Anything's possible :-).
The Devs mentioned that they were committed to OpenCL and that pressures of their workload tended to mitigate against having the time to develop a CUDA version. However my impression is that the door wasn't completely closed and that maybe with enough volunteer pressure and the lack of any progress on a more efficient nvidia opencl app version or nvidia implementation of opencl (wherever the problem lies - I wouldn't know for sure), it could happen at some future point.
I've voted with my feet :-). I have a number of GTX650s that were doing fine with BRPx but very poorly with FGRPB1G. I'm running a few just to see how things progress but the bulk have been shut down or replaced with AMD R7 370s which are doing very well.
Cheers,
Gary.

I'm not that familiar with the AMD stuff. So thanks for helping me. Really.

PS: lspci tells me: 00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Richland [Radeon HD 8670D]
But the X server says it's ARUBA aka northern island. Sometime AMD is a bit confusing (nVidia too, but that's another story).
OpenCL1.1 and above old

OpenCL1.1 and above
old hosts can run SETI maybe

Just need to be a little careful about the measure of GPU memory size, the requirement is the size reported available for OpenCL - which will be less than the physical size of the card.
I have two 768MB GPUs - that are too small, clinfo shows 708MB available, so if you have a card with physical 0.81 GB or more, you may be able to run the beta app - run clinfo for Global Memory size.
