Hi All, I am trying to configure mpich2-1.0.8 for the best performance and perhaps comparison with openmpi-1.2.9 (openmpi-1.3 is still somehow unstable). In making mpich2, I used: FC=ifort F77=ifort F90=ifort ./configure --enable-fast --enable-sharedlibs=gcc
Are these the right switches to make mpich2 performance as close as possible to that of openmpi? Any comment is highly appreciated. Best regards, Mahmoud Payami Phys. Group, Atomic Energy Org. of Iran
