Thread scheduling at the process level and at the kernel level.This topic requires more work on my part and I will give an updateddraft. There may be more than one question here. Review thedifferent allocation policies for kernel threads in relation touser threads – one to one, many to one, many to many, hybrid. Theseare sometimes referred to as an “M:N ratio” where M is the numberof user threads and N is the number of kernel threads.
a) How is the choice between “process scope” (P) and“systemscope” (S) related to these options? If “process scope” is chosen,where does the responsibility lie for scheduling threads?
b) How does Posix implement scheduling at the user thread level?If “system scope” (S) is chosen, does the programmer have anycontrol over the scheduling of her threads?
