Extending GridSim with an architecture for failure detection

Abstract

Grid technologies are emerging as the next generation of distributed computing, allowing the aggregation of resources that are geographically distributed across different locations. However, these resources are independent and managed separately by various organizations with different policies. This will have a major impact to users who submit their jobs to the Grid, as they have to deal with issues such us policy heterogeneity, security and fault tolerance. Moreover, the chunges of Grid conditions, such as resources that may become unavailable for a period of time due to maintenance and/or suffer failures, would significantly affect the Quality of Service (QoS) requirements of users.
