[slurm-users] slurm, gres:gpu, only 1 GPU out of 4 is detected

. $CUDA_DEVICE_ORDER is set to PCI_BUS_ID I can not decide if this is a slurm config error or something with gromacs, as $CUDA_VISIBLE_DEVICES is set correctly by slurm and I expect gromacs to detect all 4GPUs. Thanks for your help and suggestions, Tamas -- Tamas Hegedus, PhD Senior Research Fellow
