On our system, we typically have more reading then writing going on and was wondering what are the best parameters to tune? I have set lnet.debug to 0, and have increased max rpcs in flight as well as dirty mb. I left lru_size dynamic as setting it didn''t seem to have any affect. -- David Noriega System Administrator Computational Biology Initiative High Performance Computing Center University of Texas at San Antonio One UTSA Circle San Antonio, TX 78249 Office: BSE 3.112 Phone: 210-458-7100 http://www.cbi.utsa.edu
