The development of parallel simulation technology is s een as an enabler f or the implementation o f the virtual factory concept, the integrated simulation o f all t he systems in a factory. One important parallel simulation p rotocol, the a synchronous deadlock avoidance a lgorithm proposed by Chandy, Misra, and Bryant, h as usually been d iscussed in the c ontext of distributed memory systems. Also, nu ll m essages have normally been associated with this approach for deadlock avoidance. This paper presents a new implementation o f the CMB protocol designed for shared memory multiprocessor systems. We have successfully used this protocol, which we ca ll t he CMB-SMP protocol, to achieve useful speedups in a manufacturing simulation application, despite the fine granularity of event processing. The implementation eliminates the need for sending null m essages, without causing deadlock in the simulation. Double buffering is also used to reduce the overhead of buffer locking. It is shown that the CMB-SMP protocol outperforms a synchronous super-step protocol in terms of the speedups achieved. The paper also discusses the cache behaviour of the CMB-SMP protocol implementation since c ache misses are very expensive with today's high clock speed processors. |
