2. Introduction
Distributed Systems connected by networks provide various resources/services to clients:
Computing/storage/communication resources
Various Application Dependent Services
Resource Management Middleware
Resource Discovery
Resource allocation and scheduling
Inter-Operability Middleware
Enables the interaction of entities implemented using diverse technologies
CORBA [Valcartier (Defense Lab) project]
Web Services

3. Resource Discovery Where is the desired resource located?
Distributed Meta-directory-Based Approach
Collaborative Project with Alcatel-Lucent

4. Resource Allocation and Scheduling on Grids
Grids: A relatively new distributed system paradigm
Distributed control, Open and general protocols, Non-Trivial Quality of Sevice (QoS)
QoSMOS
Matchmaking algorithms
Scheduling algorithms
Co-scheduling of multiple resources
Collaboration with Nortel
Wireless Grids
Includes sensors and other wireless
devices
