* Create a new request type: NOOP (described below) * For all MPI_*_INIT functions, OBJ_NEW an ompi_request_t and set its type to NOOP * Ensure that the NOOP requests are OBJ_RELEASE'd when they are done * MPI_START looks at the request type; if NOOP, just return success. If not, call the PML start() function * MPI_STARTALL always pass the entire array of requests back to the PML (see next point) * Make the PMLs only process PML requests (i.e., ignore/skip anything that isn't of type PML -- such as the NOOP requests) * Add a little more param error checking in STARTALL This commit was SVN r12338.
