Argonne Leadership Computing Facility
"Lessons from 15 Years of NAMD Development with Charm++ and Message-Driven Execution"

DATE: May 13, 2010
TIME: 3:00 PM - 4:00 PM
SPEAKER: Dr. James Phillps, Beckman Institute, University of Illinois at Urbana-Champaign, Senior Research Programmer, Theoretical and Computational Biophysics Group
LOCATION: Building 240 / Conference Room 4301, Argonne National Labortory
HOST: Pete Beckman, ALCF Division Director

Description:
In 2011 IBM will install the Blue Waters computing system with over 300,000 cores and 10 petaflops peak performance in Urbana, Illinois. One of the first programs to run on the machine will be the molecular dynamics code NAMD, which was specified as a target petascale application by the NSF due to its dual status as both a highly scalable parallel code and a practical NIH-funded scientific tool with thousands of users.

NAMD is based on the prioritized message-driven execution capabilities of the Charm++ parallel runtime system. NAMD and Charm++ have evolved through a close collaboration between computer science researchers working to make parallel programming easier and computational scientists seeking flexible, reliable, and high-performance biomolecular simulation tools. In this lecture I will relate lessons learned from my career at the nexus of this unique and highly successful collaboration.
