What are the advantages and disadvantages of caching write operations on a disk?
Assume that you have a program that has a part at the beginning that is sequential in nature (for example, reading a file, that must be executed by only one processor) and takes 20 ms. Also there is a part at the end of the program that is sequential and takes 10 ms. Between these two parts, there is a perfectly parallelizable part and it take 480 ms in sequential. a) What is maximum speed-up according to Amdahl's law? b) What is the speed-up for 4 processors? c) What is the efficiency for 4 processors?
