問題詳情

2.3 For an application program running on a multi-processor system with 32 processors, it takes200 ns to handle reference in a remote memory. Assume that this application program always bas hitsin the local mem nory except for remote memor ry access involving commun nication. Proc cessors arestalled on a remote request, and the processor clock is 3.3 GHz. Assume that the base CPI (cycles perinstruction) is 0.5 and all references hit in cache. How much faster is the multi-processor if there is nocommunicatio ion versus if 0.2% of instructions s involve remote e communication. references? Hint:compute the new CPI first. The speedup is the ratio of the two CPI values.
