An Expert Fuzzy Grid Scheduler for Virtual Organizations

The recent enthusiasm in grid computing has given rise to a large amount of research on resource scheduling techniques. Most of the work on resource scheduling is aimed to minimize the total response time for a set of tasks. In this paper we propose a new scheduler that, using an expert system based in fuzzy logic, solves two kinds of problems: the execution of independent task and the execution of a directed acyclic graph (DAG). Experimental results using fuzzy scheduler show that, through our proposal, we improve other prior schedulers presented in prior literature.
