Context switch - Wikipedia. This article is about computer task switching. For the term in human cognition, see human multitasking. This enables multiple processes to. The elementary science program has been designed as a series of five topics for each grade. Each topic may be developed as a separate unit of study or linked to other. Can we write a c program to find out time spent in context switch in Linux? Could you please share code if you have one?

Short answer - no. Long answer bellow.

Context switch roughly happens when either: • User process enters the kernel via system call or a trap (e.g. Page fault) and requested data (e.g. File contents) is not yet available, so the kernel puts said user process into sleep state and switches to another runnable process.

The switch itself is one-way, so the best we can do in userland (I assume that's what you are asking) is to measure sort of an RTT, from our process to another and back. The other process also takes time to do its work. We can of course make two or more processes cooperate on this, but the thing is that the kernel doesn't guarantee that one of our processes is going to be picked next.

It's probably possible to predictably switch to a given process with RT scheduler, but I have no advise here, suggestions welcome. Varian Star Chromatography Workstation Manual Treadmill.
