ubuntu 8.10 amd64 64bit bench mark

amd 64 でテストしてみた結果


hdbench clone

無理やりコンパイルしてみた。




hdd でテスト。上と比べるとやはりライトが大分違いますが、読み込みはキャッシュが効いてる!



Super PI 104万桁 Kanada Lab Homepage japanese versionftp://pi.super-computing.org/Linux_jp/

コンパイル済みのものを使っているからそんなに変わらない?

$ ./super_pi 20
 Version 2.0 of the super_pi for Linux OS
 Fortran source program was translated into C program with version 19981204 of
 f2c, then generated C source program was optimized manually.
 pgcc 3.2-3 with compile option of "-fast -tp px -Mbuiltin -Minline=size:1000 -Mnoframe -Mnobounds -Mcache_align -Mdalign -Mnoreentrant" was used for the
 compilation.
