Facing the I/O Challenge in High Performance Computing

When: Friday, September 18, 2015
Where: PGH 232
Time: 11:00 AM

Speaker: Prof. Edgar Gabriel – UH-COSC

Host: Prof. Ernst Leiss

I/O operations increasingly dominate the overall execution time of many data intensive applications and has consequently been identified as one of the major obstacles towards Petascale systems. This talk discusses various approaches for improving the performance of I/O operations in parallel applications through collaboration between processes and multi-threading. The central focus of the presentation is on the OMPIO parallel I/O architecture, which is distributed with the highly popular Open MPI message passing library.
