[gmx-developers] The setup of gpu_id has a bug?

[dxli75]

everyone,
       When I set the gpu_id as 10-15, the GMX always give the message of PP:1,PME:1. And the job run on GPU No.1 instead of No.10-15.

       Is there a bug?


GROMACS:      gmx mdrun, version 2020.1

Working dir:  /raid/data/dxli/projects/ncovs-1rpb
Command line:
  gmx mdrun -deffnm test -gpu_id 10 -ntmpi 1 -ntomp 8

Reading file test.tpr, VERSION 2020 (single precision)
1 GPU selected for this run.
Mapping of GPU IDs to the 2 GPU tasks in the 1 rank on this node:
  PP:1,PME:1
PP tasks will do (non-perturbed) short-ranged interactions on the GPU
PP task will update and constrain coordinates on the CPUPME tasks will do all aspects on the GPU
Using 1 MPI thread

Non-default thread affinity set, disabling internal thread affinity

Using 8 OpenMP threads
