Hi All,
I have a system with multiple CPU cores. I have multiple threads assigned to particular CPU. Among these threads the main thread calls sched_yield() if it has nothing to do, I am hoping that doing so will give chance to other threads to run. But the strange behavior of sched_yield() is , even if there are ready-to-runs tasks on this CPU waiting for their turn, the task which calls sched_yield() is always running ( get scheduled) and not giving chance to any other task to run. It is consuming 100% of CPU. Is sched_yield() is broken on 2.6 Kernel?
Thanks Yogesh
