[gmx-users] different nvidia-smi/gmx GPU_IDs

[Tamas Hegedus]

Hi,

I have a node with 4 nvidia GPUs.
 From nvidia-smi output:
  0  Quadro P6000
  1  GeForce RTX 208
  2  GeForce GTX 108
  3  GeForce RTX 208

However, the order of GPUs is differently detected by gmx 2018.3
     Number of GPUs detected: 4
     #0: NVIDIA GeForce RTX 2080 Ti
     #1: NVIDIA GeForce RTX 2080 Ti
     #2: NVIDIA Quadro P6000
     #3: NVIDIA GeForce GTX 1080 Ti

Why is this? This makes difficult to plan/check the running of two gmx 
jobs on the same node.

Thanks for your suggestion.

Tamas
