Abstract
A method of counting an actual usage time of each CPU in a computer system using a plurality of computers for distributed processing of jobs comprising first counting a CPU usage time used for each job, then counting a processing wait time in memory access of each CPU whenever executing each job, subtracting the processing wait time of each CPU from the CPU usage time for every job, and setting the thus calculated corrected CPU usage time as the actual CPU usage time. A job control system has a means for realizing this method and uses the CPU usage time and the corrected CPU usage time obtained by this means to control the jobs and charge the users.
