[mvapich-discuss]Infiniband - how do I know that it is working?

[Ju JiaJia]

Hi all:

I am currently running HPL built using mvapich2 which use infiniband,
but it shows no apparently difference, compares in performance to a
build using mpich2 which uses Ethenet.

There should be some improvement in performance. I doubt whether
infiniband is working. Anyone knows how to check whether infiniband is
working ?
