使用shell监控显卡

//单卡可用:(多卡无效)
# nvidia-smi | grep -E "[0-9]+MiB\s*/\s*[0-9]+MiB" | awk '{print ($9" "$11)}' | s/\([0-9]\{1,\}\)MiB \([0-9]\{1,\}\)MiB/\1 \2/" | awk '{print $2 - $1}'

res=`nvidia-smi | \
	grep -E "[0-9]+MiB\s*/\s*[0-9]+MiB" | \ 
	awk '{print ($9" "$11)}' | \ 
	sed "s/\([0-9]\{1,\}\)MiB \([0-9]\{1,\}\)MiB/\1 \2/" | \
	awk '{print $2 - $1}'`

i=0 
for s in $res; do 
	echo $i: $s 
	i=`expr 1 + $i` 
done
