yesコマンド版とopenssl版のCPUのストレステストをしてみる。

■yesコマンド版とopenssl版のCPUのストレステストをしてみる。

$ lsb_release -d
Description:	Debian GNU/Linux 8.3 (jessie)

■yesコマンド版CPUのストレステスト

$ cat cpuyes.sh 
#!/bin/bash

CMD="yes"
MAX=$(lscpu | awk '/CPU max MHz/ {print $NF}')
N=$(top -b -n 1 | awk 'BEGIN{n=0}/'${CMD}'/{n+=1}END{print n}')

if [ $N -eq "0" ];then
  awk '/processor/{n+=1}END{print n}' /proc/cpuinfo | \
    seq 1 `xargs` | \
    awk '{print "yes >/dev/null &"}' | \
    sh &
  for n in `seq 1 10`;do 
    N=$(top -b -n 1 | awk 'BEGIN{n=0}/'${CMD}'/{n+=1}END{print n}')
    awk 'BEGIN {printf "S:"}/cpu MHz/{printf "%3.1f,",$NF/'$MAX'*100}' /proc/cpuinfo
    top -b -n 1 | awk 'BEGIN {printf "P:"}/'${CMD}'/{printf "%s,",$(NF-3)}END{printf "\n"}'
    sleep 1
  done
  pkill ${CMD}
fi

■全体の使用率は92.3%を超えない。プロセスは100%となることもある。

■openssl版CPUのストレステスト
　RSAのベンチマークのついで。

$ openssl version 
OpenSSL 1.0.1k 8 Jan 2015

■fork元と合わせて5つのopensslプロセスが実行されるスクリプト。

$ cat cpursa.sh 
#!/bin/bash

CMD="openss[l]"
MAX=$(lscpu | awk '/CPU max MHz/ {print $NF}')
N=$(top -b -n 1 | awk 'BEGIN{n=0}/'${CMD}'/{n+=1}END{print n}')

if [ $N -eq "0" ];then
  awk 'BEGIN{n=0}/processor/{n+=1}END{print "openssl speed rsa -multi",n}' /proc/cpuinfo | sh 2>/dev/null & 
  N=1;
  while [ $N -ne 0 ];do 
    N=$(top -b -n 1 | grep openssl | wc -l)
    awk 'BEGIN {printf "S:"}/cpu MHz/{printf "%3.1f,",$NF/'$MAX'*100}' /proc/cpuinfo
    top -b -n 1 | awk 'BEGIN {printf "P:"}/'${CMD}'/{printf "%s,",$(NF-3)}END{printf "\n"}'
    sleep 1
  done
fi

■実行してみる。
