super_pi under Linux VS. super_pi under Windows
发表于 : 2007-09-06 5:04
测试了一下(2的20次方,104万位左右),发现Feisty Fawn下面的super_pi要比vista下面的快很多。
Linux: 24.142( 0.892) Sec
Vista:32秒。
不知道大家的测试结果如何。
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.

super_pi不是free的,所以抱歉先不提供下载了,需要的言语一声。
