Hi,
I'm working with Open-Mpi on an infiniband-cluster and have some strange
effect when using MPI_Isend(). To my understanding this should always be
quicker than MPI_Send() and MPI_Ssend(), yet in my program both MPI_Send()
and MPI_Ssend() reproducably perform quicker than SSend(). Is there something
obvious I'm missing?

Regards,
Jeremias
