         Manish Gupta & Gyan Bhanot (International Business Machines, IBM)
                          Supercomputing and BlueGene(TM)

    BlueGene is a next-generation supercomputer from International Business
    Machines (IBM), and reportedly the world's fastest computing machine,
    having surpassed the NEC Earth Simulator, the previous leader. BlueGene(TM)
    exclusively runs the Linux operating system. This Wednesday, October 20th
    meeting will present on supercomputing, the IBM BlueGene supercomputer and
    Linux as the operating system on that machine.

    You might remember that it was an IBM supercomputer, Deep Blue, which
    passed a threshold in computation when it defeated the chess Grand Champion
    Gary Kasparov a handful of years ago. A scintillating feat when it
    occurred. For celebrity watchers and poker enthusiasts, BlueGene will soon
    be matched against Greg Raymer, the five million dollar jackpot winner of
    the 2004 World Series of Poker, in the biggest online event of its kind.
    Which is emblematic of the myriad uses the culture finds in heavy
    computation: serious and not so serious feats of work.

    BlueGene fits inside a single rack, crunches out an astounding six
    teraflops of operations, and runs Linux. Quote IBM:

      Today BlueGene ranks as the number one supercomputer on the TOP500 list
      of fastest computers. BlueGene is poised to reach 360 peak teraflops
      when a 64 rack system with over 130,000 IBM PowerPC® processors is
      installed in 2005 at the Lawrence Livermore National Laboratory.

      The BlueGene charter was to develop a massively parallel computer that
      would advance the understanding of the mechanisms behind biomolecular
      phenomena via large-scale simulation, and explore novel ideas in
      massively parallel machine architecture and software. Starting earlier
      this year with the availability of operational hardware, hands-on
      experiences with many differing applications have shown that the
      BlueGene architecture is applicable to a broad set of parallel workloads
      found across a variety of disciplines. Today, IBM and its partners are
      exploring a growing list of high performance computing applications
      including life sciences, financial modeling, hydrodynamics, quantum
      chemistry, molecular dynamics, astronomy and space research and climate
      modeling. Other promising areas of interest include Grid Computing,
      business intelligence, risk and compliance, aerodynamics study and
      testing, and manufacturing processes.

    In the first talk on BlueGene Manish Gupta will give an overview of the
    hardware and software design of the BlueGene/L system. In particular, he
    will describe the challenges in scaling the system to thousands of nodes,
    while maintaining a familiar programming and development environment. He
    will present our early results and experiences in dealing with these
    challenges. In the second talk Gyan Bhanot will describe the history of MPP
    computers, what kinds of problems and codes can run efficiently on such
    massively parallel distributed memory machines and how the BlueGene
    machine, like its predecessors, promises to open up new frontiers in
    science, industry and technology.

   About Manish Gupta & Gyan Bhanot:

    Gyan Bhanot:

    Gyan Bhanot received his Ph.D in Theoretical Physics from Cornell
    University and did research in lattice gauge theory and statistical
    mechanics for many years at IAS Princeton, CERN and ITP Santa Barbara. He
    was lured into supercomuting by Danny Hillis, who told him about his dream
    to build a computer which "would be proud of me." Gyan currently works at
    IBM Research and his research interests are in modeling complex systems -
    in particular, he is interested in why protein and gene pathways are robust
    and specific at the same time.

    Manish Gupta:

    Manish Gupta is a Research Staff Member and Senior Manager of the Emerging
    System Software department at the IBM T. J. Watson Research Center. His
    group has developed system software for the BlueGene/L machine and conducts
    research on software issues for high performance server systems. He
    received a Ph.D. in Computer Science from the University of Illinois at
    Urbana-Champaign in 1992, and has worked with IBM since then. He has
    co-authored several papers in the area of high performance compilers,
    parallel computing, and high performance Java Virtual Machines.
