Can not spectate any kind of context switching at a core that is assigned for many processes.

Isn’t there something wrong ? Also, is there any tool I can trace the core usage of the specific process ?

In the case of spectating the context switching in terms of OS I decided to assign many process to single one CPU core (core 9). I was expecting to see these processes to execute in concurrent manner. But in that case each one of them correctly sits on the dedicated core but in “Running” state.
