Reducing waiting and idle time for a group of jobs in the grid computing

Johnson's rule is a scheduling method for the sequence of jobs. Its primary goal to find perfect functions reduce amount idle time, and it also reduces total time required complete all functions. It suitable purposes two in specific time-dependent both where factor only parameter used this way. Therefore, not work computers network, there are many factors affecting completion such as CPU speed, memory, bandwidth, size data. In research, will adopt by adding that affect so becomes site’s job waiting group
