Hi Sharlaan, On 8/8/06, Sharlaan <ml@xxxxxxxx> wrote: i have test the sedf scheduling, but I does not understand to what corresponds period and slice. SEDF tries to satisfy each domain's slice/period specification so long as they don't violate capacity. For example: Name ID Period(ms) Slice(ms) Lat(ms) Extra Weight Domain-0 0 10.0 5.0 0.0 1 0 vm1 1 10.0 5.0 0.0 1 0 In this case both Domain-0 and VM1 are *guaranteed* 5ms in every 10ms window, provided they have enough work to do. I have test many configuration with there options, but, i don't understand ... somebody can explain this to me ? For some more info, look under docs/misc/sedf_scheduler_mini-HOWTO.txt Note that SEDF is no longer the default scheduler.
