Thank you Jeff for your replay.
I read the documentation but I couldn't find any parameters that modify the
pinned memory at startup for ssi rpi ib module.
Thanks.

Are you saying that you can't launch more than 2 processes on a node
using IB?

If so, it could well be because of pinned memory limitations. You can
use run-time LAM SSI parameters to decrease the amount of memory that
is pinned at startup -- see the LAM/MPI User's Guide
(http://www.lam-mpi.org/using/docs/) for specific details about the
Infiniband RPI SSI parameters.
