hpc_benchmark New Member Steve Colde Join Date: Jan 2010 Posts: 15 Rep Power: 16	I downloaded openfoam source tar ball and thirdparty tar. just modify mpi to hpmpi (bashrc, setting.sh), and run ./Allwmake to compile everything. It is successful, then I run cavity test, it is much much slower than binary from OpenFoam website (openmpi based). What can be the reason? Even I recompiled with my own openmpi, it is also very very slow too. I don't understand the difference. MPI library shouldn't contribute that much (>100 times slower)
