I have few questions about the sched_yield function because I'm seeing that it is not functioning as intended in my code. Many times I see that the same thread runs again and again, even in the presence of other threads, when I try to yield it by calling sched_yield.
Also If I have multicores, will sched_yield yield for threads running on all cores, or only one core. Say for example I have Threads 1, 2 and 3 running on core 1 and Threads 4, 5 and 6 on core 2 and If sched_yield is called from Thread 2, will it be replaced by Thread 1 and 3 only, or 1, 3, 4, 5 and 6 are all possible? I am asking this because in .Net Thread.Yield only yields to threads running on the same core/processor.
