Detect NVIDIA GPU NUMA nodes #959

Karolina example with 4 GPUs:

GPU0 <-> CPUs 48-63 <-> CPU NUMA NODE 3
GPU1 <-> CPUs 48-63 <-> CPU NUMA NODE 3
GPU2 <-> CPUs 16-31 <-> CPU NUMA NODE 1
GPU3 <-> CPUs 16-31 <-> CPU NUMA NODE 1

found with for i in $(nvidia-smi -x -q | grep "gpu id" | awk -F "\"" '{print $2}' | awk -F ":" '{print "0000:" $2 ":" $3}' | tr '[:upper:]' '[:lower:]'); do echo $i; cat "/sys/bus/pci/devices/$i/numa_node"; done.
