Yes MM... But here a single node has 16cores not 64 cores.
The 1st two jobs were with OMPI-1.4.5.
16 cores of single node - 3692.403
16 cores on two nodes (8 cores per node) - 12338.809
The 1st two jobs were with OMPI-1.6.5.
16 cores of single node - 3547.879
16 cores on t
As I said, the degree of impact depends on the messaging pattern. If rank A
typically sends/recvs with rank A+!, then you won't see much difference.
However, if rank A typically sends/recvs with rank N-A, where N=#ranks in job,
then you'll see a very large difference.
