Installed openmpi 1.4-4 as well as the MPI development suite on the test cluter. Configured host based authentication to obviate the ssh password authentication. Compiled a test case program. Seeing a 50% speed improvement when splitting the workload over 3 worker nodes (all communication simulated ethernet in a virtual environment). In our current model the executable does not need to be copied to the worker nodes as it appears in the NFS mounted file system. The user only needs to execute mpirun with the correct parameters. Work to do: - test with torquepbs and qsub directives in order to reserve worker nodes and CPUs appropriately. - develop and practice data sharing methodologies.
