Efficient Service Task Assignment in Grid Computing Environments

چکیده
Grids facilitate the employment of various nodes comprising supercomputers, storage elements and databases that are distributed for resolving computational demanding problems in many disciplines of science and commerce (Foster, 2001). To utilize Grids effectively, an efficient allocation algorithm is needed to assign service tasks to Grid resources. Thus, assuming that a user wishes to perform a specific service task, which can be served by various candidate Grid nodes (CGNs), a problem that should be addressed is the assignment of the requested service task to the most appropriate Grid node. In this paper, the pertinent problem is called Service Task Allocation (STA).

متن کاملAn Efficient Genetic Algorithm for Task Scheduling on Heterogeneous Computing Systems Based on TRIZ
An efficient assignment and scheduling of tasks is one of the key elements in effective utilization of heterogeneous multiprocessor systems. The task scheduling problem has been proven to be NP-hard is the reason why we used meta-heuristic methods for finding a suboptimal schedule. In this paper we proposed a new approach using TRIZ (specially 40 inventive principles). The basic idea of thi...
