Schedulers
|
|
Also see Rt-Xen, which includes two real-time schedulers.
- RT-global: which uses a global run queue to hold all VCPUs (in runnable state). It is CPU mask aware, and provides better resource utilization, as VCPU can migrate freely between physical cores (within CPU mask)
- RT-partition: which uses a run queue per physical CPU. In this way, each physical CPU only looks at its own run queue to make scheduling decisions, which incurs less overhead and potentially better cache performance. However, load-balancing between physical cores is not provided in the current release.
