PORTLAND COMPILERS

[Craig Tierney]

If all you want to do is compile and run MPI processes you can just
get the PGI workstation set for $560.  You can ask PGI about this
themselves.  I asked the same questions before and this is what
they told me.

Intel are very good for P4/Xeon systems.  I haven't tried their compiler
on P3s (but SSE support is very useful).  Intel did well on AMD systems
as well, but for MY codes the Intel boxes were still faster.
