Title: GRID ARCHITECTURE

GRID ARCHITECTURE

What is Grid ?
"...a flexible, secure, coordinated
resource-sharing among dynamic collections of
individuals, institutions, and resources." - Ian
Foster

  • Why Grid ?
  • The principle benefits that the Grid will bring
    are
  • Enabling more effective and seamless
    collaboration of dispersed communities, both
    scientific and commercial.
  • Enable large-scale applications comprising of
    1000s of computers, large-scale pipelines etc.
  • Transparent access to "high-end" resources from
    your desktop
  • Provide a uniform "look feel" to a wide range
    of resources
  • Location independence of computational resources
    as well as data.

Layered Grid Architecture
GRID Protocol Architecture
Internet Protocol Architecture
5
Fabric Layer
Contains the resources that are to be shared.
This include computational power, data storage,
sensors etc.
Connectivity Layer
Contains the communication and authentication
protocols required for Grid-specific network
transactions.
6
Resource Layer
Control the secure negotiation, initiation,
monitoring, control, accounting, and payment of
sharing operations on individual resources
Collective Layer
Contains protocols and services that are global
in nature and capture interactions across
collections of resources.

Classification of Applications
  • Distributed Supercomputing
  • High-throughput
  • On-demand
  • Collaborative

Implementing the Grid
Middlewares
  • Globus
  • Condor
  • PUNCH
  • Legion

10
Technical Challenges
  • Predictability and robustness of accuracy and
    performance
  • Run time resource management
  • Support for multiplicity of resource environments
  • Security, access policies and payment mechanisms
  • Hidden complexities
