  • I want to thank Chris for the kind remarks, and all of you for your interest. So what is this about? Let me have a couple of tries, to narrow it down.

grid computing grid computing Presentation Transcript

  • Grid Computing UITS IT Seminar Series June 2001
  • Beyond the Net, lies the Grid.
    • The Net allows users everywhere to share information.
    • The Grid will allow users to share raw computing power.
            • It’s under construction.
  • What is a Grid?
    • persistent networked environments integrating geographically distributed supercomputers , large databases , and high end instruments
    • coordinated resource sharing and problem solving in dynamic virtual organizations
  • Grid computing is related to but not identical with
    • Parallel computing
    • Distributed computing
    • Pervasive computing
  • Who is building them?
    • Demonstration – SC98
    • TransPac link from Internet2 to APAN
    • NASA, DOE, DOD, NSF
  • It’s for real.
    • Used to construct:
        • collaborative engineering systems
        • real-time instrument control systems
        • problem solving environments
        • to perform record-setting scientific simulations.
  • You don’t have to be a computer scientist…
  • The bandwagon
  • Student Technology Centers
    • Nearly 1000 new computers
    • Fast ethernet connections
    • SETI@Home screensaver accumulated CPU-hours at the rate of 552 processors on a 24x7 basis
    • Challenges: resource management, security, migration
    • Testbed project – Condor
  • The goal is to create …
    • A scalable, seamless extension of your access point
          • through pervasive networks
    • to a set of resources
          • tied together by a set of ubiquitous common distributed services .
  • A scalable, seamless extension of your access point through pervasive networks ...
  • A scalable, seamless extension of your access point through pervasive networks to a set of resources …
    • Parallel computing is harder
        • There’s more to think about.
        • The technology is less mature.
    • It need not even help
        • Moving bits is slower than crunching them.
        • Formula for success: communication/computation << 1
  • A scalable, seamless extension of your access point through pervasive networks to a set of resources tied together by common services.
  • To Do:
    • Building the middleware, protocols, interoperable communications libraries
    • Building resource management
    • Building social infrastructure
        • Economic exchange mechanisms
  • Building on the Internet, the WWW
    • Uniform naming
    • A seamless, scalable information service
    • A powerful new meta-data language: XML
      • SOAP - simple object access protocol -
        • Uses XML for message encoding, HTTP for protocol.
        • XML-RPC may become standard mechanism for Grid Services.
  • Why bother? Because you have to.
    • Big calculations – more processors, more memory
  • Other reasons:
    • Share resources
    • Share ideas
  • Who is building the Grid at IU?
    • Computer Science and Engineering departments
    • Other departments
    • UITS
  • IUB CS Department Extreme Computing Group
      • Current Projects
