Bus based multiprocessor
WebMultiprocessor solution: Step 1: when P fails, put process to sleep; on V just wakeup everybody, processes all try P again. Step 2: label each process with semaphore it's waiting for, then just wakeup relevant processes. Step 3: just wakeup a single process. Step 4: add a queue of waiting processes to the semaphore. On failed P, add to queue. WebOct 5, 2010 · In bus based multiprocessor systems, appropriate coherence actions can be taken if coherence. is detected. These are called snoopy protocols. The name snoopy comes from snoop,
