Roadrunner Technical Seminars: March-June 2008

As part of our technical work on the Roadrunner project, we are holding a technical seminar series in which we will describe in detail the current Roadrunner platform as it will be delivered, the technical work we have done thus far from a computer science,  numerical algorithms, and applications perspective, and finally hold a couple of panel discussions on future programming models and platforms.   The schedule is as follows.  Additional announcements will be made as the dates approach, particularly since they may change subject to availability of the venue (and speakers). Unless otherwise noted below, these talks are 1000-1130 in the Study Center.

March 13: "Roadrunner Platform Overview," LA-UR-08-1994, Ken Koch, CCS-DO.
Introduction to the final Roadrunner system hardware and nuances.  Intended for people unfamiliar with the system and underlying technology.

March 18: "Overview of Applications, Results, and Programming," LA-UR-08-2412, John Turner, CCS-2
Overview of applications, technical results, and programming approaches.  Intended to prepare the audience for more detailed application talks to follow.

March 19: "Overview of Modeling, Performance, and Results," LA-UR 08-2037, Darren Kerbyson, CCS-1
Overview of modeling and prediction approaches for Roadrunner, providing technical details as to how performance modeling work is done and its impact on systems and applications.

April 10: "Application 1: SPaSM," Sriram Swaminarayan, CCS-2
Discussion of the SPaSM application and what was done to put it on Roadrunner, what results were obtained, what was learned, and what is next.

April 22: "Application 2: VPIC," LA-UR-08-2672, Ben Bergen, CCS-2
Discussion of the VPIC application and what was done to put it on Roadrunner, what results were obtained, what was learned, and what is next.

April 23: "Application 3: SWEEP," LA-UR 08-2844, Mike Lang, CCS-1
Discussion of the SWEEP application kernel and what was done to put it on Roadrunner, what results were obtained, what was learned, and what is next.

April 24: "Application 4: Milagro 1," LA-UR-08-2757, Tim Kelley, CCS-2
Discussion of the Milagro application and one approach to put it on Roadrunner, what results were obtained, what was learned, and what is next.

May 6: "Application 5: Milagro II," LA-UR-08-3023, Paul Henning, CCS-2
Discussion of a different approach to put Milagro on Roadrunner, what results were obtained, what was learned, and what is next.

May 8: "Direct Numerical Simulations of Fluid Flow on Roadrunner," LA-UR-08-3200, Jamal Mohd-Yusof, CCS-2
Why Direct Numerical Simulation is important and what was done to put it on Roadrunner, what results were obtained, what was learned, and what was next.

May 29: "Panel Discussion: Hybrid Computing Programming Models," moderated by John Turner, CCS-2.
Panel participants TBD.
Discussion of various programming approaches on Roadrunner in particular and hybrid computing in general, tools, and future activities.

June 3: "Panel Discussion: Future Platforms," moderated by Adolfy Hoisie, CCS-1.
Panel participants TBD.
Discussion of future computing platforms and how they will be similar to, and differ from, Roadrunner.

This series of talks is designed in this particular order, which will introduce you to the Roadrunner platform in particular, hybrid computing in general, and gradually work through increasingly complex application domains, problems encountered, and results achieved.  These will be 1 hour highly technical talks meant to pass along technical information and lessons learned with plenty of time for questions and discussion.
