Venue: CS 101 Abstract:
Blue Gene is an IBM Research project dedicated to exploring the frontiers in supercomputing: in computer architecture, in the software required to program and control massively parallel systems, and in the use of computation to advance our understanding of important biological processes such as protein folding.
The full Blue Gene/L machine is being built with the Department of Energy's NNSA/Lawrence Livermore National Laboratory in California, and will have a peak speed of 360 Teraflops and is expected to be delivered by the end of 2005. In November 2004, Blue Gene/L occupies the #1 position in the TOP500 supercomputer list by giving a performance of 70.72 Terraflops on the linpack benchmark. A growing list of applications including hydrodynamics, quantum chemistry, molecular dynamics, climate modeling and financial modeling are being run on BlueGene/L now.
In this talk I will describe the architecture of the BlueGene/L machine and the different decisions made in its design that enabled it to achieve the top spot in the supercomputing list. I will also describe some of the research being carried at IBM India Research Lab in this area.
BlueGene/L has been a six year joint research project between IBM and Lawrence Livermore national labs.
