No real solution yet, but forcing the transfer protocol to TCP makes the 
calculations proceed. Don't know what kind of performance hit this implies 
(if any) though. For the record, also tried uDAPL, which caused a similar 
MPI_Send error to the above. So for example:

   export MPI_IC_ORDER=TCP
   export MPIRUN_SYSTEM_OPTIONS="-subnet x.y.z.å"

Apparently a HP-MPI (02.02.05.00) problem, on another machine with MVAPICH 
InfiniBand, the problem doesn't occur.

Have a nice day,
