In computer science and software engineering, busy-waiting, busy-looping or spinning is a technique in which a process repeatedly checks to see if a condition is true, such as whether keyboard input or a lock is available. Spinning can also be used to generate an arbitrary time delay, a technique that was necessary on systems that lacked a ...
Similarly, at the next level, N − 2 will proceed, etc., until at the final level, only one process is allowed to leave the waiting room and enter the critical section, giving mutual exclusion. [4]: 22–24 Unlike the two-process Peterson algorithm, the filter algorithm does not guarantee bounded waiting. [4]: 25–26
