Via boot parameter sched-gran=core (or sched-gran=socket) it is possible to change the scheduling granularity from cpu (the default) to either whole cores or even sockets. All logical cpus (threads) of the core or socket are always scheduled together. This means that on a core always vcpus of the same domain will be active, and those vcpus will always be scheduled at the same time. This is achieved by switching the scheduler to no longer see vcpus as the primary object to schedule, but "schedule units". Each schedule unit consists of as many vcpus as each core has threads on the current system. The vcpu->unit relation is fixed. I have done some very basic performance testing: on a 4 cpu system (2 cores with 2 threads each) I did a "make -j 4" for building the Xen hypervisor. With This test has been run on dom0, once with no other guest active and once with another guest with 4 vcpus running the same test. The results are (always elapsed time, system time, user time): sched-gran=cpu, no other guest: 116.10 177.65 207.84 sched-gran=core, no other guest: 114.04 175.47 207.45 sched-gran=cpu, other guest: 202.30 334.21 384.63 sched-gran=core, other guest: 207.24 293.04 371.37 The performance tests have been performed with credit2, the other schedulers are tested only briefly to be able to create a domain in a cpupool. Cpupools have been moderately tested (cpu add/remove, create, destroy, move domain). Cpu on-/offlining has been moderately tested, too. The complete patch series is available under: git://github.com/jgross1/xen/ sched-v1 Changes in V1: - cpupools are working now - cpu on-/offlining working now - all schedulers working now - renamed "items" to "units" - introduction of "idle scheduler" - several new patches (see individual patches, mostly splits of former patches or cpupool and cpu on-/offlining support) - all review comments addressed - some minor changes (see individual patches) Changes in RFC V2: -
