Workshop "Capability Computing with Blue Gene/L"

Joint Workshop of the John von Neumann Institute for Computing and IBM Deep Computing

7 - 8 September 2004
Research Centre Jülich

Blue Gene/L

Scope of the Workshop

With Blue Gene/L, IBM introduces a new and extremely powerful high-end computer architecture for capability computing. In the near future, a leadership system with a performance of nearly 400 TFlops including 65.536 specially manufactured PowerPC processors will be installed at the Lawrence Livermore National Laboratory. What makes Blue Gene/L so attractive are its scalability and its low requirements for power, cooling and floor space. On the other hand, its enormous number of processors will certainly pose special problems to programmers.

The aim of this workshop is to get a first assessment of Blue Gene/L and to find out which types of applications best match its architecture. Speakers from the IBM developer group will give insight into the hardware and software architecture of Blue Gene/L. Scientists from several application areas will discuss their specific computational requirements and IBM specialists will describe the opportunities that Blue Gene/L offers to these fields and report first experiences. Additional talks will provide a general intorduction to the options of future high-end machines.
