Just a heads up, there are a number of places in mesh_refinement.C and parallel.h where MPI_CHAR is used for collective operations with MPI_MIN/MPI_MAX operators.
Unfortunately, MPI does not mandate that MPI_MIN/MPI_MAX work for char data types. This has bitten me in the past with LAM, and it looks like OpenMPI continues in the tradition of dying when computing the max of a char. I think SGI's MPT had issues with this as well. So, I'm checking in some fixes which basically uses <(unsigned) short int> for <(unsigned) char> where needed. Just wanted all to know it is MPI, not me, being pedantic this time ;-) ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
