Introduction to Grid Computing

Ann Chervenak

Carl Kesselman

And the members of the Globus Team

the computataional grid
The Computataional Grid
  • Emerging computational and networking infrastructure
    • pervasive, uniform, and reliable access to remote data, computational, sensor, and human resources
  • Enable entirely new approaches to applications and problem solving
    • remote resources the rule, not the exception
  • Wide-area distributed computing
    • national and international
what can you do with one
What Can You Do with One?
  • Combine dozens of supercomputers to solve a single problem
  • Link realtime satellite data feeds with distributed computational and display systems
  • Enable schools across the country to participate in interactive simulations and data analysis
  • Interactively combine the output of many independent servers to analyze a new genome
  • Build a network of immersive virtual reality sites to collaboratively design a new vehicle

why now
Why Now?
  • The Internet as infrastructure
    • Increasing bandwidth, advanced services
  • Advances in storage capacity
    • Terabytes, petabytes per site
  • Increased availability of compute resources
    • clusters, supercomputers, etc.
  • Advanced applications
    • simulation based design, advanced scientific instruments, ...
today s information infrastructure
Today’s Information Infrastructure
  • Network-centric: simple, fixed end systems; few embedded capabilities; few services; no user-level quality of service

O(106) nodes

tomorrow s infrastructure not just faster and more reliable
Tomorrow’s Infrastructure:Not Just “Faster and More Reliable”
  • Application-centric: heterogeneous, mobile end-systems; many embedded capabilities; rich services; user-level quality of service

grid services middleware
Grid Services (“Middleware”)
  • Standard services that
    • Provide uniform, high-level access to a wide range of resources (including networks)
    • Address interdomain issues of security, policy, etc.
    • Permit application-level management and monitoring of end-to-end performance
  • Middleware-level and higher-level APIs and tools targeted at application programmers
    • Map between application and Grid

today
Today
  • Definition of grid computing
  • Syllabus, class requirements
  • How does grid computing differ from traditional distributed computing?
  • Where do grids get their names?
  • What basic services must be provided by a grid infrastructure?
course syllabus
Course Syllabus
  • Part 1: The Basics of Grid Computing
    • Grid book and recent papers
    • General discussion of each topic followed by focus on the Globus approach
  • Part 2: Advanced Topics
    • Focus on recent papers
    • Examine some other systems, some Globus tools in greater detail
  • Prerequisites:
    • Courses in operating systems and networks, preferably at the graduate level
    • Prefer some distributed systems knowledge
