You'd be amazed at how good those ex-DEC compiler writers are... http://www.coyotegulch.com/reviews/almabench.html In this heavily numerical benchmark, the best Intel Fortran and C++ timings are 3.24x faster than the best g++ 3.2.1 timings. -- +------------------------------------------------------------+ | Ron Johnson, Jr. mailto:[EMAIL PROTECTED] | | Jefferson, LA USA http://members.cox.net/ron.l.johnson | | | | "Basically, I got on the plane with a bomb.
