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. Bud Dodson -- M. L. Dodson Email: mldodson-at-houston-dot-rr-dot-com Phone: eight_three_two-five_63-386_one
