What is Grid Computing?

  • Geographically diverse
  • Heterogeneous hardware and software
  • Large-scale resource sharing
  • Uniform, abstract access
slide-3
SLIDE 3

Why is it called a “Grid”?

Because of the “Power Grid Metaphor” Describes a hope for the future Sounds better than “Super-DUPER-Computing

slide-4
SLIDE 4

Why is this necessary?

  • Research is outpacing computing power
  • To connect more scientists with the

computing power they need

  • Eventually corporations and maybe

indivduals

Ok, ok, let’s see some Grids already!

TerraGrid Information

  • 14 Petabytes Storage
  • 40 Teraflops of computation
  • 27-40 Gb/S Network
  • Across 9 different sites, with more to be

added

Major Hurdles for Grids

  • Accurate Grid-wide Information
  • Accessing resources in a uniform fashion
  • Moving and accessing data across the grid
  • Security that is not tied to individual sites
  • Grid-aware scheduling

The answer for now? Middleware

  • Cactus
  • CORBA
  • Enterprise JavaBeans

Tomorrow’s Answer?

  • Grid-aware applications
  • global Grid compilation system

– able to compile and optimize a Grid-aware application to a target Grid configuration

  • NSF - Grid Application Development

Software (GrADS)

And after that?

  • Who knows?
  • Grid-enabled VoIP
  • Super-sized file-swapping?
