Benchmarking the SGI: Floating point faster than integer?

[news]

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

But if you want raw multiplication speeds, each of the FORTRAN
multiplies is actually four machine instructions: 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!!!
