Assume that we are going to compute C on a single core shared memory computer as well as a four-core shared memory machine. Calculate the expected speedup on the 4-core computer, disregarding any memory concerns.

Assume that every 18 months a new generation of CPUs with twice as many cores is produced. In three years, how much more off-chip memory bandwidth will a CPU need to retain the same per-core performance?

By assuming 32 is a two digitnumber, consider memory storage of a 64-bit word stored at memory word 32 ina byte-addressable memory.(a) What is the byte address of memory word 32?(b) What are the byte addresses that memory word 32 spans?(c) Draw the number 0xF1234567890ABCDE stored at word 32 in both big-endianand little-endian machines. Clearly label the byte address corresponding to eachdata byte value.

As a sort-of prediction for your midterm assignment, how many CPU cores do you think is ideal? Hint: think about Amdahl's Law, which describes the theoretical maximum speedup for a parallel program.
