Hi,
The device numbering is consistent accros all applications, except nvidia-smi
that ignores the CUDA_DEVICE_ORDER
environment variable.
The problem is that by default the device ordering is FASTEST_FIRST
while nvidia-smi
uses PCI_BUS_ID
.
To make your applications consistent with nvidia_smi
, just add export CUDA_DEVICE_ORDER=PCI_BUS_ID
to your bashrc (or equivalent) such that every application uses nvidia-smi
's ordering.
