Xinu - Setting new priority for a Suspended state process
I have created a process X in Xinu along with other two processes (y, z). The y and z are high priority than X, so they both are running as per scheduling policy.In the backend, I want to increment the...

View ArticleIs a schedulable unit of CPU time slice process or thread?
I want to clarify whether "a schedulable unit of CPU time slice" is "process" or "thread" (kernel managed thread). What I mean by "schedulable unit of CPU time slice" is the unit which CPU scheduler of...
