ROMIO at SC 2017

November 9th, 2017
Comments Off on ROMIO at SC 2017

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.

Comments Off on Rajeev Thakur speaking about history of MPI-IO

Rajeev Thakur, original author of ROMIO, will be speaking at the “Celebrating 25 years of MPI” symposium on 25 September.   It’s one of the workshops held in conjunciton with EuroMPI 2017.  If you are traveling to Argonne for the conference, stop by and let him know what you think about ROMIO.

ROMIO (and more) I/O tutorial at SC 2015

November 12th, 2015
Comments Off on ROMIO (and more) I/O tutorial at SC 2015

SC 2015 is just a few days away. ROMIO will be part of our Sunday I/O tutorial. “Parallel I/O In Practice”: our 11th full-day tutorial on Parallel I/O hardware, software, tools and strategies. ROMIO, Parallel-NetCDF, HDF5, and Darshan will be the focus of the afternoon half of the day. File systems and storage hardware will be the focus of the morning.

You will also be able to find Rob Latham wandering around Austin: he would crawl over a mountain of vendor trinkets for a conversation about MPI-IO. Don’t be shy!

ROMIO on the RCE Podcast

February 20th, 2012
Comments Off on ROMIO on the RCE Podcast

Brock Palen and Jeff Squyres chatted with Rajeev Thakur and Rob Latham about ROMIO for the RCE Podcast. That discussion was episode 66.

We talked about ROMIO’s history, how ROMIO serves as the MPI-IO implementation for several MPI implementations, file system support, and what’s coming down the road.
