Hi,
Indeed, the standard way provided by CUDA to expose a subset of GPUs to an
application is the CUDA_VISIBLE_DEVICES (note the "S" ending); I did not
realize that is something you were interested in, I thought you wanted to
avoid using GPUs.
Also note (for anyone interested), a when using a
Hi,
Thanks, setting this variable allowed me to start GROMACS without errors
using the CPU.
The problem is that this method prevents me from using other free GPUs on
the host, but I would like to do this.
I also found out that setting the CUDA_VISIBLE_DEVICE variable to available
GPUs at the time
Hi,
This is an issue in one of pre-detection checks that trips due to
encountering exclusive / prohibited mode devices.
You can work around this by entirely disabling the detection using the
GMX_DISABLE_GPU_DETECTION environment variable.

fatal error if at least one video card is busy on the host at that time.
