Special debugging arguments


Up: In Case of Trouble Next: Acknowledgments Previous: HP-UX

These are currently undocumented, and some require configure options to have been specified (like -mpipktsize and -chmemdebug). The option -mpiversion is useful for finding out how your installation of mpich was configured and exactly what version it is. The options include:

-mpedbg
If an error occurs, start xterms attached to the process that generated the error. Requires the mpich be configured with -mpedbg and works on only some workstations systems.

-mpiversion
Print out the version and configuration arguements for the mpich implementation being used.


These arguments are provided to the program, not to mpirun. For example,
   mpirun -np 2 a.out -mpiversion
