--------------------------------------
Summary: Introduce a work stealing Process scheduler.
Key: MESOS-8588
URL: https://issues.apache.org/jira/browse/MESOS-8588
Project: Mesos
Issue Type: Epic
Components: libprocess
Reporter: Benjamin Mahler
Currently, libprocess uses a work sharing Process scheduler, by which all
workers take work from a global shared runnable Process queue. This has some
performance implications, for example the shared global queue can have a high
degree of contention, and Processes can migrate across cores frequently (this
can be even more expensive on NUMA systems).
We can introduce an alternative work stealing scheduler, in which each worker
has its own queue. When this worker runs out of items, it steals from another
worker's queue (stealing attempts could be done with cache locality / NUMA in
mind).
The process scheduler could ideally be a run-time option if it does not
introduce performance overhead over a compile time option.
