Grid environment, being a collection of heterogeneous and geographically distributed resources, is prone to many kinds of failures such as process failures, resource and network failures. In this paper, we address the problem of resource failure. Resources in grid oscillate between being available and unavailable to the grid. When and how they do so, depends on the failure characteristics of the machines,...
Most of the existing job scheduling algorithms for grids have ignored the security problem with a handful of exceptions. Moreover, existing algorithms using fixed- number job replications will consume excessive resources when grid security level changes dynamically. In this paper, a security aware and fault tolerant scheduling (SAFTS) algorithm based on adaptive replication is proposed which schedules...
Grid computing has been a hot spot recent year. In grid computing applications, resource management and job scheduling are the most crucial problems in grid computing systems. In this paper, we try to present a novel agent-based dynamic grid resource management model considering both the resource management and job scheduling as a coalition integrity, so as to gain good robust, scalability, efficiency,...
