More details on graphics + compute mode in README #12
Comments
is it this option:
Looks like I can't set it:
My GPU is GeForce GTX 1080 Ti. |
It is almost certain that your GPU is already set in the correct mode, so there should be no problem (that advice from the readme is relevant only in a tiny number of cases, and AFAIK never for GeForce cards). Do you get errors when using DIRT? |
I shall update the README to be more precise about this, or remove the note entirely. |
Thanks @pmh47! I think we should mention that Compute + Graphics mode is enabled by default for some cards, and maybe give some brief pointers on how to check and set those modes. I'm not using DIRT directly, but working on a similar project that also uses EGL + interop. Right now I'm getting into this issue
This test runs fine in my local machine, but it doesn't run on a docker container on our cluster. I thought it was because the graphics mode was not enabled, but perhaps that's not the issue. I noticed some differences from nvidia-smi -q locally and on cluster though:
On cluster:
Looks like Display Mode is disabled on the cluster while it's enabled locally. |
'Display Mode' should not matter for EGL offscreen rendering. Rather, I think you have a problem with finding / using the right version of the EGL library. Running |
Thanks, I resolved this problem some time ago. It was not because of graphics + compute mode. |
and state that the default is almost always correct (#12)
Hi,
Could you give more details on this point in the README file:
How can I ensure that? I looked at nvidia-smi manpage but it wasn't obvious to me, and google shows references to a tool call gpumodeswitch that I don't know how to get.
