assume that 16 processor are available for adding n numbers and that it is possible to divide the list of numbers into 16. Furthermore, a processor can pass on the result of an addition (in the form of a single number) to the processor next to it in time tw. How long will it take in the following scenarios? (a) All 16 processor are connected in a ring. (5 points) (b) The 16 processors are connected in two rows of 8 processors each, and each processor can communicate with the processors next to it (5 points)
