Compute Mode "Prohibited" (GRID M60)
Dear all, I´ve virtualized a NVIDIA Tesla M60 in order to use it from several virtual machines. When I apply the GRID M60-8Q GPU Profile for a virtual machine I can see, with the "nvidia-smi.exe", that the Compute Mode is "Default": C:\Program Files\NVIDIA Corporation\NVSMI>nvidia-smi Thu Sep 07 18:11:22 2017 +-----------------------------------------------------------------------------+ | NVIDIA-SMI 370.12 Driver Version: 370.12 | |-------------------------------+----------------------+----------------------+ | GPU Name TCC/WDDM | Bus-Id Disp.A | Volatile Uncorr.

Dear all,
I´ve virtualized a NVIDIA Tesla M60 in order to use it from several virtual machines.
When I apply the GRID M60-8Q GPU Profile for a virtual machine I can see, with the "nvidia-smi.exe", that the Compute Mode is "Default":

So, could somebody tell me how to set Compute Mode "Default" for this GRID M60-2Q Profile?
Thank you very much!

Hi Same answer as this post: https://gridforums.nvidia.com/default/topic/1603/nvidia-grid-vgpu/compute-m-prohibited-in-tesla-vgrid-m60-2q/ You guys posted the same thing 3 hours apart :-) If you want to run CUDA on vGPU profiles other than 8Q, you need a Pascal GPU. I'm inquiring with NVIDIA Engineering to understand whether this is a technical limitation between Maxwell / Pascal GPUs Regards

If you want to run CUDA on vGPU profiles other than 8Q, you need a Pascal GPU.

I'm inquiring with NVIDIA Engineering to understand whether this is a technical limitation between Maxwell / Pascal GPUs

Nice quick response from the NVIDIA Engineering Team as to why CUDA is only available with multiple vGPU profiles on Pascal GPUs: [b][i]"... Pascal has a new hardware feature called Preemption that allows Compute on vGPU profiles. Preemption is a feature that allows task Context switching. It gives the GPU the ability to essentially pause and resume a task ..."[/i][/b] This feature doesn't exist on Maxwell, which is why you can only use CUDA with an 8Q vGPU profile or Passthrough. Regards

Yes, we posted the same task by mistake! We work together but it seems we are a little "disconnected" :-) Thank you very much both of you BJones and mcerveny for your great help. It was very useful for us! Kind regards
