Er, it depends. gcc is a pretty good compiler for integer, but it's way behind the curve for numerical code and peak options. For Fortran, there's also the issue that performance-sensitive use of intrinsics really needs them expanded and optimized in-line. I don't know if g95 or gfortran have implemented these yet, but I do see people showing relatively poor performance for those cases. -- greg (disclaimer: we sell compilers, but then again, we compare against gcc in a regular basis...) _______________________________________________ Beowulf mailing list, [email protected] To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
