Necessary and sufficient conditions for a solution to the
c.s. problem:
1. Mutual Exclusion --- if is executing in one of its
critical sections, no , , is executing in its critical
sections.
2. Progress --- a process operating outside of its
critical section cannot prevent other processes from
entering theirs; processes attempting to enter their
critical sections simultaneously must decide which process
enters eventually.
3. Bounded Waiting --- a process attempting to enter
its critical region will be able to do so eventually.
Assumptions:
1. No assumptions made about relative speed of
processes
2. No process may remain in its critical section
indefinitely (may not terminate in its critical section)
3. A memory operation (read or write) is atomic ---
cannot be interrupted. For now, we do not assume
indivisible RMW cycles.
