Like SPEC2000fp, for example?
Advanced Micro Devic Gigabyte GA-7DX Motherboard, 1.33GHz 445
Intel Corporation Intel D850GB motherboard(1.5 GHz, Pe 558
If you compile your own codes, and you can get the Intel compiler,
than SPEC2000fp is probably a lot more relevant than the numerous
benchmarks where old compilers were used. This is similar to the
situation with the Pentium Pro, which was terrible on 16-bit windows
code, but great on 32-bit Linux code. The press said bad things, but
Linux users were happy.

That's true in the overall market. I thought this was the Beowulf
mailing list? Do you think that a majority of beowulf users can
re-compile their own codes, or do they use shrink-wrapped binaries
from vendors who are unwilling to re-compile for the P4?
