(C) Suppose we have an application running on a 32-processor multiprocessor, which has a 200ns time to handle reference to a remote memory. For this application, assume that all the references except those involving communication hit in the local memory hierarchy, which is slightly optimistic. Processors are stalled on a remote request and the processor clock rate is 3.3GHz. If the base CPI (assuming all reference hit in the cache) is 0.5, how much faster is the multiprocessor if there is no communication versus if 0.2% of the instruction involve a remote communication reference?
