[HEADS UP] USE_FORTRAN knob has been added

[M. L. Dodson]

Hello,

Thanks for the USE_FORTRAN knob.  Are there plans to add g95 to
the list of supported Fortran compilers?

In an earlier communication, I mentioned that AMBER, a molecular
mechanics software suite I use, would not compile with gfortran.
I tested gfortran and AMBER two days ago, and gfortran is now able
to compile AMBER.  On benchmarks, however, gfortran showed only
approximately 70% of the performance of g95 on compute-bound
benchmarks.

The benchmarks were run with a dual core AMD64 and FreeBSD-CURRENT
of a very recent date.  The schedsmp.diff diff was applied.  I do
not have a Linux install on the machine ready to compare, but the
FreeBSD / g95 combination is now able to keep pace with published
Linux benchmarks (same software).  These benchmarks are 100%
compute-bound.
