[OMPI users] sepran package dead lock

[Brock Palen]

We have a user who uses the sepran1206 package.  It works for him on  
lam, mpich2 and OMPI up to problem sizes i see in the debugger (ddt)  
that both rank 0 and rank 1 call PMPI_SEND()
Is PMPI_SEND the same as MPI_SEND?

also why would it work with lam and mpich2 ?
If we up the btl_sm_eager_limit it works, (obviously due to the  
blocking nature of both calling MPI_SEND)
but I am confused as to why lam works and ompi does not.
