ROMIO

If you would like to learn more about I/O in High Performance Computing, come check out our SC 2017 tutorial Parallel I/O in Practice. We will cover the hardware and software that makes up the software stack on large parallel computers. MPI-IO takes up a big chunk of time, as do the I/O libraries which typically sit on top of MPI-IO.
If you are interested in ROMIO, you hopefully are familiar with Darshan for collecting statistics and otherwise characterizing you your I/O patterns. These other Darshan-related events will likely be of interest to you:
Thursday’s “Analyzing Parallel I/O” BoF by Phil Carns and Julian Kunkel.  Several guests will share their experiences in analyzing I/O performance and participate in a panel discussion:

Glenn Lockwood will be presenting a paper entitled “UMAMI: A Recipe for Generating Meaningful Metrics through Holistic I/O Performance Analysis” at the PDSW-DISCS workshop on Monday as well!  It highlights how to integrate I/O monitoring data from multiple sources into a coherent view.
