What is difference between sched_batch and sched_other scheduling?

Question

I am working on Ubuntu project. Have not found clear difference between sched_batch and sched_other. Can anyone tell me the difference?

Answer 1

Threads that are scheduled with sched_batch are assumed to be non-interactive, but CPU bound and optimized for throughput. Thus, this policy is more cache-friendly. The default sched_batch timeslice is 1.5 seconds. In addition, in case of SMP, sched_batch will migrate to a core with high idleness (with respect to non-batch threads).
