I'm trying to work with the sppm code form LLNL: http://www.llnl.gov/asci_benchmarks/asci/limited/ppm/asci_sppm.html
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 thanks, john.
