Question: Give a high - level description of an algorithm to compute the prefix sum of n numbers on a p node hypercube. Let n p

Give a high-level description of an algorithm to compute the prefix sum of n numbers on a p node hypercube. Let n p be an integer greater than 1. Assuming that it takes time tadd to add two numbers and time tw to send a message of unit length between two directly-connected nodes, give an exact expression for the total time taken by the algorithm.
