Sorry if this is inappropriate here. I'm finally growing from clusters of single CPUs to a machine with multiple CPUs, which means that I need to start taking note of NUMA issues. I'm looking for information on how to achieve that with mpi under linux. I'm currently using mpich2, but I don't mind switching if needed.
Things are actually more complex as this is a mixed GPU/GPU (CUDA) system so I'm also looking for how to effectively transfer data between GPUs siting on different PCIe slots and find the affinity between GPUs and CPUs. Also at what stage is the support for using MPI to copy between GPUs? Thanks for any pointers _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
