  1. Embedding the e-IRG discussion Patrick J.C. Aerts Supercomputers in Europe

  2. Why? • During the meetings in November 2004 and March 2005 it was concluded that a grid without relevant (general purpose) facilities is rather empty • The European Science Grid should comprise: • A fast and low latency hybrid network • Major data storage and servicing facilities • Competitive edge advanced facilities for reseach computing • Support of various kinds • Organisation

  3. What kind of facilities? • General purpose? • Special purpose • Mixture? • Discipline bound? • More than 1, 2, …5?

  4. General/Special purpose • The European Science Grid from scratch: • A landscape of various architectures • “TOP5”-level systems • Gridwise connected (“DEISA-like”) • Consecutively installed, exploiting More’s Law • Different locations in Europe

  5. Discipline bound? • Distinguish hardware and operations from knowledge and support • Is there a single most suitable architecture for all codes in use in one discipline? • Isn’t the grid software particularly supporting the principle of the most suitable machine for each code?

  6. Questions • Are SC needed on European Scale? • Per discipline or per architecture? • At what performance (price) level? • How many more than one? • All at the same time or consecutively? • As a European effort or as (bundled) national efforts? • As integral part of the European Science Grid? • Build on top of the DEISA set-up or otherwise?
