I'm trying to work with the sppm code form LLNL:

I built openmpi and sppm on an 8-way shared memory Linux box.

The error I get is:
[ty20:07732] *** An error occurred in MPI_Allreduce
[ty20:07732] *** on communicator MPI_COMM_WORLD
[ty20:07732] *** MPI_ERR_OP: invalid reduce operation
[ty20:07732] *** MPI_ERRORS_ARE_FATAL (goodbye)

it happens in both 1.0.1 and 1.0.2rc1
