Method and system for job scheduling

摘要

Logical processors/hardware contexts are assigned to different jobs/threads in a multithreaded/multicore environment. There are provided a number of different sorting algorithms, from which one is periodically selected on the basis of whether the present algorithm is giving satisfactory results or not. The period is preferably a super-context interval. The different sorting algorithms preferably include a software/OS priority. A second sorting algorithm may include sorting according to hardware performance measurements. The judgement of satisfactory performance is preferably based on the difference between a desired number of time quantum attributed per super-context switch interval to each job/thread and a real number of time quantum attributed per super-context switch interval to each job/thread.
