I'm search the best Message Passing implementation to use in the University Beowulf Cluster, and I was wandering if MPI can determine which CPU to send a process.With MPI I can determine the host and the number of process, and with -npernode , the number of process per nodes, but that guaranty that if I put 4 quad cores in some host list, and use -npernode 3, it will execute exactly 1 process per CPU in which host? And I can determine the CPU to send a process, like CPU1 or CPU0 , some CPU affinity on execution time?
Best Regards. Otavio Augusto.
