ABSTRACT:
A multiprocessor system includes a plurality of identical central subsystem (CSS) units, a plurality of memory and input/output (I/O) subsystem units which connect in common to an asynchronous bus system. Each CSS subsystem unit includes a cancel command mechanism for enabling each such unit to effectively withdraw from the asynchronous bus or switch the state of a resource such as a memory or I/O lock mechanism included in such subsystem without otherwise disturbing the state of such subsystems.
