Yes, I'm sure I'm picking up the newly built version. I've run ompi_info to verify my path is correct.
I've have a little more information now... I rebuilt openmpi 1.4.2 with the '--enable-debug' option to configure and when I run a simple mpi program on 2 processors with an MPI_Reduce() call: MPI_Reduce(&mypi, &pi, 1, MPI_DOUBLE, MPI_SUM, 0, MPI_COMM_WORLD); I see: [macsierra:89600] *** An error occurred in MPI_Reduce: the reduction operation MPI_SUM is not defined on the MPI_DOUBLE datatype [macsierra:89600] *** on communicator MPI_COMM_WORLD [macsierra:89600] *** MPI_ERR_OP: invalid reduce operation [macsierra:89600] *** MPI_ERRORS_ARE_FATAL (your MPI job will now abort) Thanks, Mike > On May 23, 2010, at 12:43 PM, Doug Reeder wrote: > Mike, > Are you sure that you are getting the openmpi that you built and not > the one supplied w/ OS X.
