[OMPI users] An idea about a semi-automatic optimized parallel I/O with Open MPI

bout the whole process. Please be free to ask any details about this system/concept. I will try my best to explain it. I am happy if someone can take part in the discussion. Thanks! Best Regards! Xuan Wang

default params in their default MCA param files. Not saying that a database is a bad idea - just saying it is a design departure. We haven't done it because monitoring performance automatically hurts the performance of the app being monitored. On Jun 13, 2012, at 7:13 AM, Xuan Wang wrote: > H
