Benchmarking the SGI: Floating point faster than integer?

[James Helman]

[repost, original apparently lost in NNTP land]

The program is a rather extreme benchmark.  A more balanced program
representative of your application would make more sense as a
purchasing critereon.

But if you want raw multiplication speeds, each of the FORTRAN
multiplies is actually two loads, a multiply and a store.  If you edit
the assembly code to discount the loads and stores by repeating the
mul instruction N times, the FP multiply is actually 3X faster than
the integer!!!
