The --debug option is probably not doing what you think in this case. Here's what the man page says: For debugging: -debug, --debug Invoke the user-level debugger indicated by the orte_base_user_debugger MCA parameter. -debugger, --debugger Sequence of debuggers to search for when --debug is used (i.e. a synonym for orte_base_user_debugger MCA parameter). -tv, --tv Launch processes under the TotalView debugger. Deprecated back- wards compatibility flag. Synonym for --debug. Hence, the --debug flag is trying to invoke a parallel debugger. It doesn't actually show debug-level information about what is happening in mpirun or the MPI processes. -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
