Petascale Computing Experiences on Blue Gene/PPrimary Session Leader:
Katherine Riley (Argonne National Laboratory)
Secondary Session Leaders:
Intrepid, the world's largest Blue Gene/P, is a 40-rack (163,840 core) Blue Gene/P at Argonne National Laboratory. At this size, computational scientists are facing new challenges with scalability and performance. With well over one hundred applications ported to Blue Gene/P, there have been a lot of lessons learned. Load balancing at this scale, single core performance, memory limitations and parallel scalability are some of the challenges the application groups have faced. Groups are also using Blue Gene/P as the stepping stone to explore new programming models for the next generation of supercomputers. We invite anyone interested in the architecture or have experiences with the P architecture, to make presentations and join a discussion on the science, algorithms and performance issues on Blue Gene/P. We will discuss both successes and challenges.
