EARNINGS-BASED TIME-SHARE SCHEDULING

A precise earnings-based time-share scheduler schedules multiple jobs in a computer system by apportioning earnings, at scheduler ticks. Earnings are apportioned to jobs based on actual time a job spent in a queue requesting execution on a central processing unit (CPU) in the computer system between scheduler ticks and amounts of time jobs ran on the CPU between scheduler ticks. At the end of a time slice, a job is selected for execution on the processor based on earnings apportioned to each job.
