Hi Duke You probably mean MVAPICH2 (not MPIPICH2). Both Open-MPI and MVAPICH2 (which is a port of MPICH2 to run on IB), are easy to install (once you have OFED/OpenIB). Open-MPI is a bit more flexible, as it supports TCP/IP, IB, and other protocols, and has a number of configurable features, several of them at runtime. Both have mailing list support. It really doesn't hurt to install and use both, and they don't conflict. http://www.open-mpi.org/ http://mvapich.cse.ohio-state.edu/overview/mvapich2/ MPICH2 doesn't support IB, but works over TCP/IP and other protocols. http://www.mpich.org/ Also, if you decide to use a resource manager (which you probably should in a cluster), such as Torque+Maui, or SGE/OGE, or Slurm, install it first, and build Open-MPI with resource manager support. This makes parallel job launching and management much simpler. (The three above have mailing lists also.) http://www.adaptivecomputing.com/products/ http://www.clusterresources.com/products/maui-cluster-scheduler.php https://computing.llnl.gov/linux/slurm/ http://www.oracle.com/us/products/tools/oracle-grid-engine-075549.html I hope this helps, Gus Correa > _______________________________________________ > Beowulf mailing list, [email protected] sponsored by Penguin Computing > To change your subscription (digest mode or unsubscribe) visit > http://www.beowulf.org/mailman/listinfo/beowulf _______________________________________________ Beowulf mailing list, [email protected] sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
