Message Queue Window Showing Pending Receive Operation

Note:   TotalView displays all of the receive operations that are maintained by the IBM MPI library. You should set the environment variable MP_EUIDEVELOP to the value DEBUG if you want blocking operations to be visible; otherwise, only non-blocking operations are maintained. For more details on the MP_EUIDEVELOP environment variable, consult the IBM Parallel Environment Operations and Use manual.
