</div>Thanks Peter and preeti, I had seen that intel link and had read but<br>
was not very clear with it,<br>
with both explanations and new links I am clear.<br></blockquote><div><br></div><div></div></div><div><br></div><div>Sorry, I am still learning all these. On top of scheduling domain, there is also cpusets, and both are intertwined (for eg, look into sched_fair.c), and cpu inside cpuset can be offline/online, or made allow/disallowed to be used. </div>
