How are you determining that it is using IPoIB?

Your processes are probably running asynchronously. You could perhaps
try tracing program execution and look at the timeline. E.g.,
http://www.open-mpi.org/faq/?category=perftools#free-tools . Or, where
you have MPI_Wtime calls, just capture those timestamps on each process
and dump the resu

network time protocol, resource management, scheduler, etc. The t

Hi,

Is there any way to execute MPI applications on only Infiniband stack i.e.

Can we execute MPI applications using libibverbs, librdma, or some other
libraries ?
Hi,
As much as I know about OMPI, THREAD_LEVEL_MULTIPLE value is set to "yes" by
default.
