Reinventing Scheduling for Multicore Systems

Reinventing Scheduling for Multicore Systems
High performance on multicore processors requires that schedulers be reinvented. Traditional schedulers focus on keeping execution units busy by assigning each core a thread to run. Schedulers ought to focus, however, on high utilization of on-chip memory, rather than of execution cores, to reduce the impact of expensive DRAM and remote cache accesses. A challenge in achieving good use of on-chip memory is that the memory is split up among the cores in the form of many small caches. This paper argues for a form of scheduling that assigns each object and its operations to a specific core, moving a thread among the cores as it uses different objects.
