1. (11) True or False: (1) DRAM and Disk access times are rapidly converging. (1) Measuring performance on multiprocessors using linear speedup instead of execution time is a good idea. (1) Amdahl’slaw applies to parallel computers. (1) You can predict cache performance of Program A by analyzing Program B. (1) Computer components fail suddenly ,with little warning. (1) Linear speedups are not needed to makemultiprocessors cost-effective. (1) It is not necessary to simulate very manyinstructions in order to get an accurate perfor- mance measure of the memory heirarchy. (1) A program’slocality behavior is constant overthe run of an entire program. (1) Communication is a significant problem for parallel processor systems. (1) Memory Bandwidth is the most important thing when designing a memory system. (1) The instruction set architecture impacts the implementability of a virtual machine moni- tor.
