  1. Grid & Utility Computing: Do they really mean Pervasive Services ICPS 2006 – Panel Manish Parashar TASSL, Rutgers University, Piscataway, NJ USA

  2. Definitely not! • Separate communities, conferences, journals, etc. • GGF, EGA, Grid, SC, CCGrid, HPDC, ICPS, Pervasive, Percom, IJGC, Ubicomp, … • Separate history/perspectives • HPC, big science, sensor networks, real-time • Separate demigods • John McCarthy, Fenando Corbato, Ian Foster, Mark Weiser • Separate standards bodies and standards • IETF, OASIS, DMTF, W3C, SNIA, WSRF, OGSA, 802.XX, OMA, … • Separate software • TeraGrid, Globus, Unicore, eBiquity, Gaia, Datafountain, Oxygen, SmartSpace, Aura, AccessGrid, EGEE, OSG, … • Separate sponsors, patrons, funding sources

  3. So what are they about? • Grid/Utility Computing • Seamless, secure, on-demand access to (and aggregation of) geographically distributed computing, communication, data resources • I.e., provide computing resources (computers, communication, data, instruments) as pervasive services • Pervasive/Ubiquitous Computing • Integrate computation/communication into the environment • I.e., provide information and context as pervasive services

  4. Hmm, they do have similar underlying isssues/challenges … • Large scale distributed computing • Service description, discovery, and composition • Security, authentication and trust • Data/Information management • Dynamic assembly of components • Dynamic adaptation to state and context • Availability, reliability, trust, … • Management and self-management • Standards and interoperability • …

  5. Also, … • Grid/Utility applications have pervasive aspects • Grid/Utility computing uses pervasive computing to couple with the real world • E.g., provide dynamic (real-time) data, information to scientific, engineering, business processes • Pervasive application have Grid/Utility aspects • Pervasive computing uses Grid/Utility computing to provides services • E.g., assimilate/process large amounts of information

  6. Grid computing! Pervasive Services Ubiquitous computing Utility Computing! Pervasive Grid Envs/Apps Pervasive computing! On-demand computing! The Big Picture …

  7. Different aspects of an overall solution? • Applications that require • Knowledge-based • Information-driven • Context-aware • Computationally-intensive • Distributed solutions! Grid/Utility Pervasive/ Ubiquitous PGE Autonomics Semantics • Crisis management, monitor and predict natural phenomenon, monitor and manage engineering systems, optimize business processes

  8. The key barrier “ our ability to reason are limited by our experiences …” L. Wittgenstein • The biggest challenges are non-technical • People from disparate fields with different perspectives, experiences, languages, etc., must work and evolve together!
