When parallelizing an application, the ideal speedup is speeding up by the number of processors. this is limited by two things: percentage of the application that can be parallelized and the cost of communication. amdahl’s law takes into account the former but not the latter. a. [10] < 1.10> what is the speedup with n processors if 80% of the application is parallelizable, ignoring the cost of communication? b. [20] < 1.10> what is the speedup with 8 processors if, for every processor added, the communication overhead is 0.5% of the original execution time. c. [20] < 1.10> what is the speedup with 8 processors if, for every time the number of processors is doubled, the communication overhead is increased by 0.5% of the original execution time?

Suppose we have a byte addressable computer that has a 32-byte cache with 8 bytes per block. the memory address is 8 bits long. the system accesses memory addresses (in hex) in this exact order: 6e, b9, 17, e0, 4e, 4f, 50, 91, a8, ab, ad, 93, and 94. (a) assuming the cache is direct mapped, what memory addresses will be in cache block 2 after the last address has been accessed? (b) assuming the cache is direct mapped, what is the hit ratio for the entire memory reference sequence given, assuming the cache is initially empty? (c) assuming the cache is 2-way set associative with a lru replacement policy, what is the hit ratio?
