Since serial and parallel jobs conflict considerably, scheduling both types of jobs concurrently is a difficult task. Two major strategies are in common use: partitioning the cluster (thus(More)
Security and data integrity are important aspects in the fields of Grid and cluster computing. When these two areas are combined, the security issues intermingle and new security concepts are needed to ensure protection of both Grid users and local cluster users. In this paper, a novel dual laned Demilitarized Zone (DMZ) to protect local clusters from Grid(More)
