Nova在NFV场景下会提供NUMA相关高级特性，这里提供一个脚本查看计算节点的NUMA相关信息。

#!/bin/bashfunction get_nr_processor(){ grep '^processor' /proc/cpuinfo | wc -l}function get_nr_socket(){ grep 'physical id' /proc/cpuinfo | awk -F: '{ print $2 | "sort -un"}' | wc -l}function get_nr_siblings(){ grep 'siblings' /proc/cpuinfo | awk -F: '{ print $2 | "sort -un"}'}function get_nr_cores_of_socket(){ grep 'cpu cores' /proc/cpuinfo | awk -F: '{ print $2 | "sort -un"}'}echo '===== CPU Topology Table ====='echoecho '+--------------+---------+-----------+'echo '| Processor ID | Core ID | Socket ID |'echo '+--------------+---------+-----------+'while read line; do if [ -z "$line" ]; then printf '| %-12s | %-7s | %-9s |\n' $p_id $c_id $s_id echo '+--------------+---------+-----------+' continue fi if echo "$line" | grep -q "^processor"; then p_id=`echo "$line" | awk -F: '{print $2}' | tr -d ' '` fi if echo "$line" | grep -q "^core id"; then c_id=`echo "$line" | awk -F: '{print $2}' | tr -d ' '` fi if echo "$line" | grep -q "^physical id"; then s_id=`echo "$line" | awk -F: '{print $2}' | tr -d ' '` fidone < /proc/cpuinfoechoawk -F: '{ if ($1 ~ /processor/) { gsub(/ /,"",$2); p_id=$2; } else if ($1 ~ /physical id/){ gsub(/ /,"",$2); s_id=$2; arr[s_id]=arr[s_id] " " p_id }} END{ for (i in arr) printf "Socket %s:%s\n", i, arr[i];}' /proc/cpuinfoechoecho '===== CPU Info Summary ====='echonr_processor=`get_nr_processor`echo "Logical processors: $nr_processor"nr_socket=`get_nr_socket`echo "Physical socket: $nr_socket"nr_siblings=`get_nr_siblings`echo "Siblings in one socket: $nr_siblings"nr_cores=`get_nr_cores_of_socket`echo "Cores in one socket: $nr_cores"let nr_cores*=nr_socketecho "Cores in total: $nr_cores"if [ "$nr_cores" = "$nr_processor" ]; then echo "Hyper-Threading: off"else echo "Hyper-Threading: on"fiechoecho '===== END ====='

查询结果示例：
