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]

Resource Discovery

Where is the desired resource located? Distributed Meta-directory-Based Approach

– Collaborative Project with Alcatel-Lucent

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
