yes, open-mpi was config'd with: ./configure --prefix=/raid1/mpich F77=ifort FC=ifort --with-mx=/opt/mx --with-mx-libdir=/opt/mx/lib openmpi_info shows mx support: # ompi_info | grep mx MCA btl: mx (MCA v1.0, API v1.0, Component v1.1.2) i'm running mpi with: mpirun --mca btl mx,self --n 32 --nolocal mm5.mpp ____________________________________________________________________________________ Sponsored Link Mortgage rates near historic lows: $150,000 loan as low as $579/mo.
