Grid Computing: Hype or Killer System? Michel Bercovier School of Engineering and Computer Science Hebrew University of Jerusalem Abstract: A rapid survey of Grid computing vs. classic HPC will be given, using some of its Gurus' reports (Gordon Bell, Ian Foster). It includes Peer to Peer and other asynchronous computations systems such as SETI@home. Presentation will also focus on implication in Mechanical Numerical Simulations. Obvious economics pro are limited by management questions, available software tools as well as problem structures . Roadmap for its acceptance is outlined, including the present US and European efforts, and the coming WEB Services paradigm.
