Grid Computing

• Characteristics
• Simultaneous multiple QoS properties
• Multiple resources from multiple providers
• Middleware Examples Globus, ICENI, Legion
• Challenges

• Tight coupling with COTS and grid infrastructure
  middleware (GIMs)
• Proliferation of GIMs
• No single sign-on secure access to resources
• Provisioning restrictions of COTS m/w and GIMs

• Need to satisfy simultaneous multiple QoS
• Accidental complexities assempling and deploying
  grid applns
• Lack of resource reservation patterns
• Difficulties in resource and QoS provisioning

Grid TAO (GriT) Architecture
4
Grid Service Provider (GSP)

• Web service access to underlying middleware
• Single sign-on
• Collaborations via session initiation protocol
  (SIP)

5
Meta-Resource Broker (MRB)

• Broker for resources
• Maintains abstractions of concrete resources
• Uses CORBA parallel and part objects

6
MRB Part Object Core

• Uses TAOs pluggable protocol framework to talk
  Grid protocols
• Used for resource discovery and reservation

Concluding Remarks

• GriT enhances TAO/CIAO
• Meta resource broker
• Patterns for resource reservation and QoS
  adaptation
• Uses Model Integrated Computing tools
