spuer pi

下記ftpサイトにsuper_pi-jp.tar.gzがあるのでDLしてくる。
ftp://pi.super-computing.org/Linux_jp

展開すると以下のようになる

$tar zxvf ./super_pi-jp.tar.gz
...
$ls
Readme_jp.txt  pi  super_pi  super_pi-jp.tar.gz

この中のpiを実行するとsuper_piを測定を実行する

MFLOPSとは、
MFLOPS:million floating operations per second
の略であり、1秒間に実行する浮動小数点命令の数を示す。

下記URLから"ソースコード（C, static allocate version）"のtableよりサイズMのlzhファイルを
DLしてくる。(file name:cc_himenoBMTxp_m.lzh)
http://accc.riken.jp/HPC/HimenoBMT/program1.htm

これを展開すると以下のようになり、ファイル名を変えてmakeする。

$lha -e cc_himenoBMTxp_m.lzh
...
$ls
cc_himenoBMTxp_m.lzh  himenobmtxps.c  makefile
$mv himenobmtxps.c himenoBMTxps.c
$make

実行ファイルbmtができるのでこれを実行するとCPUの処理速度を測定してくれる。
