xmpi: A graphical user interface for MPI program development. MPI is a standard for writing parallel processing programs using a well defined Message Passing Interface. XMPI can acquire and display extensive detail on an application's MPI communication, including the following: o process synchronization status: running, system or blocked o message queue contents o source, destination, root ranks o MPI function name o communicator o data type o message count o tag The above information is acquired from on-demand snapshots of application status using debugging hooks in the MPI implementation or from a trace log of communication activity.
