Revision 1805 - (show annotations)
Wed Sep 24 23:39:00 2008 UTC (11 years, 10 months ago) by ksteube
File MIME type: text/x-python
File size: 6420 byte(s)
Added python-level methods getMPISizeWorld() and getMPIRankWorld() for MPI process info.
Test suite run_inputOutput.py runs on any number of cores now, hybrid may still be a problem.
