CPU time comparison with different gcc compilers

newcfd

On a 64-bit computer. Simple pressure calculations:
   gcc-4.2.2(64bit): real  time  2m34.093s
   gcc-3.2.3(64bit): real  time  3m22.832s
   gcc-3.2.3(32bit): real  time  2m43.555s
   gcc-4.1.3(64bit): real  time  6m20.290s
  If you have gcc-4.2.2(32bit), try to do comparison. 64-bit gcc compilers seem not to be able
to make use of the 64-bit CPU structure. Do not use gcc-4.1 compiler. [br][br][以下内容由 newcfd 在 2008年01月09日 04:50am 时添加] [br]
to check gcc version, type gcc --version
