A certain algorithm may be parallelized onto a cluster of N nodes such that each node in the cluster operates on 1/Nth the total data, but must also exchange its results with the (N1) other nodes in the network. A. Assuming a data set size of 2MiB(2220 bytes), a communications latency of 90 ns and a network throughput of 125106 bytes per second to each node (note that this is not the same as 125230 bytes/sec), create a spreadsheet tab labeled "Communication Time". On that tab, compute the information below and copy the results into this worksheet
