ANIX is a multiprocessor operating system to be used in the backbone Asynchronous Transfer Mode (ATM) switches. In ANIX, memory contention by processes running on different CPUs is managed with a protocol called WWWH (when to sleep, who to sleep, where to sleep, and how to sleep). Tools are needed to test, debug, and tune the system running WWWH . This paper describes the experience and practice in design of SHMON, a performance tool that monitors the dynamic behavior of the running system. Copyright © 2004 John Wiley & Sons, Ltd.
