A "job" is the entire application, while a "proc" is just one process in that application. In this case you could use either one as you are checkpointing the entire job, but all this activity is occurring inside each proc. So I'd suggest defining it as a proc state since it only really involves local actions. If you like, I can define the required code in the trunk and let you fill in the event functionality. > > Adrian > _______________________________________________ > devel mailing list > de...@open-mpi.org > http://www.open-mpi.org/mailman/listinfo.cgi/devel
