Which uDAPL implementation are you using, over what sort of network?
I'm guessing OpenIB/InfiniBand, but want to make sure.
One other thing I noticed, you say native IB works, yet looking at your
ompi_info/config.log neither OpenIB nor MVAPI support was enabled.

Hello,
I finally managed to run open MPI with uDAPl but all MPI programs hang
up, when they use MPI_Recv. If I use TCP or native InfiniBand instead,
it works. Maybe you have an idea where the problem could be.
Thanks
Andreas
