Error handlers

The MPI Standard specifies a mechanism for installing one's own error handler, and specifies the behavior of two predefined ones, MPI_ERRORS_RETURN and MPI_ERRORS_ARE_FATAL. As part of the MPE library, we include two other error handlers to facilitate the use of dbx in debugging MPI programs.

    MPE_Errors_call_dbx_in_xterm 

    MPE_Signals_call_debugger 

These error handlers are located in the MPE directory. A configure option (-mpedbg) includes these error handlers into the regular MPI libraries, and allows the command-line argument -mpedbg to make MPE_Errors_call_dbx_in_xterm the default error handler (instead of MPI_ERRORS_ARE_FATAL).
