Low level Windows 7 kernel architecture interview with Arun Kishan
In my recent wanderings I came across this msdn interview with kernel engineer Arun Kishan covering his redesign of the way the new Windows 7 kernel handles spinning off multiple processes. Up until recently, there was a mechanism known as a spin lock in place that checked for permissions and resources for a process that wanted launching. The problem with this was that with the explosion in cpu cores comes an explosion in the multithreading capacities of hardware. The singular spin lock model just can't keep up. So if you're itching to know how Kishan solved this problem and you're willing to put your hour where your mouth is - or if you just love tech discussion involving whiteboard notes and diagrams - this video is for you!
