In fact, here's the verbatim results directly from Mr. >Dongarra's benchmark. This is from a SPARC 370 workstation, with FORTRAN >1.2, compiled with f77 -O. I believe these performance numbers were obtained using the latest FORTRAN compiler 1.3 at the highest optimization level (-fast -O4). The default for -O is -O2 which is a compromise between optimization and compile time. Michael V. Iarrobino EMail: mike.iarrobino@East.Sun.COM
