Unformatted text preview: 1. (11) True or False: (1) Measuring performance on multiprocessors using linear speedup instead of execution time is a bad idea. (1) Amdahl’s law applies to parallel computers. (1) You can predict cache performance of Program A by analyzing Program B. (1) Linear speedups are needed to make multiprocessors cost-effective. (1) It is not necessary to simulate very many instructions in order to get an accurate perfor- mance measure of the memory heirarchy. (1) Scalability is almost free. (1) A program’s locality behavior is constant over the run of an entire program. (1) Communication is not 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 does not impact the implementability of a virtual machine monitor. (1) Professor Farrens never wore shorts to class. 2. (3) What is the goal of the memory heirarchy? What two principles make it work? 3. (12) What do the following acronyms stand for: SMP TPC COMA OLTP VMM SRAM NUMA MPP DSM MIMD SIMD SISD For the next 6 problems, circle the correct answer. 4. (1) Which type of cache miss can be changed by altering the mapping scheme?...
