By default, the OFED installation of MVAPICH will automatically use IB. So no special option is needed to run it on IB. It might be helpful to check out our user guide sections on running MPI jobs over InfiniBand. http://nowlab.cse.ohio-state.edu/projects/mpi-iba/download-mvapich/mvapich_user_guide.html#x1-190005.2 In addition, you could also look at our "Troubleshooting" section for commonly encountered problems and their solutions. http://nowlab.cse.ohio-state.edu/projects/mpi-iba/download-mvapich/mvapich_user_guide.html#x1-290007 > 4. we are using cpi.c sample is there any other > sample we can use for testing as well as benchmark?? You could use the OSU benchmarks.
