Concurrent Control with "Readers" and "Writers" The problem of the mutual exclusion of several independent processes from simultaneous access to a "critical section" is discussed for the case where there are two distinct classes of processes known as "readers" and "writers." The "readers" may share the section with each other, but the "writers" must have exclusive access. Two solutions are presented: one of the case where we wish minimum delay for the readers; the other for the case where we wish writing to take place as early as possible.
