Abstract — A computational Grid is a hardware and software infrastructure that provides dependable, consistent, pervasive, and inexpensive access to high-end computational capabilities. Grids are emerging as a new computing paradigm for solving grand challenge application in Science, Engineering and Economics through sharing and collaboration of heterogeneous resources. Scheduling is one of the research issues in grid. Grid Scheduling is defined as the process of making scheduling decisions among resources from different administrative domains. The main problem in computational grid resource allocation is to discover suitable resources and to schedule separate tasks of an application on those resource in such a way to satisfy deadline requirement of the job with minimum execution time and cost. We propose a cuckoo optimization algorithm for optimal job allocation of resources on each node. This system will allocate the job optimally by considering the deadline requirement of the users and also the minimal execution time
