Do you really see any speed improvements? When we first purchased the
Opteron cluser, we tested the combination of gcc and Absoft fortran.
The results were very disappointing. Our program ran twice as slow
as the same program compiled with 32 bit compilers running on Windows.
We even considered purchasing Pathscale compilers, but the process
is pain in the neck so we stayed with Intel 32 bit compilers v.7(we
didn't renew the support contract in time).

Previous versions of IVF have been disappointing. IVF 9.0 does have
one merit, it made my program ran about 5% faster.
