Selection and Advanced Reservation of Backup Resources for High Availability Service in Computationa during the resource allocation phase and how to make advanced reservation for backup resources are challenging issues for grid environment to provide high availability service. In this paper, we proposed a backup resources selection algorithm base on resources clustering, then devised several polic

Adaptive Job Scheduling for a Service Grid Using a Genetic Algorithmaverage execution time of scheduling . jobs to .(≤ .) machines on the Grid. Two models are proposed to predict the execution time of a single job or multiple jobs on each machine with varied system load. The single service type model is used to schedule jobs of one single service to a machine while

Resource Scheduling Algorithms for Grid Computing and Its Modeling and Analysis Using Petri Net of tasks, but also expected communication time when calculating expected completion time. In the paper, the execution cost of tasks and budget of application are selected as QoS and an algorithm XMin-min with QoS is also proposed. An extended high-level timed Petri net (EHLTPN) model suiting schedu

Architecture of Grid Resource Allocation Management Based on QoS the layered structure of Grid QoS. Based on the analysis of the content of grid resource allocation management (GRAM) based on QoS, this paper puts forward the architecture of GRAM based on QoS. Through mapping, converting and negotiating the QoS parameters, it can implant the user’s requirement ab

Effective OpenMP Extensions for Irregular Applications on Cluster Environmentsutations is called irregular problem. In this paper, we propose some extensions to OpenMP directives, aiming at efficient irregular OpenMP codes to be executed in parallel. These OpenMP directives include scheduling for irregular loops, inspector/executor for parallelizing irregular reduction, and e
