Finding prefix sums is a generalization of global sum. rather than simply finding the sum of n values the prefix sums are the n partial sums a. devise a serial algorithm for computing the n prefix sums of an array with b. parallelize your serial algorithm for a system with n processes, each of c. suppose n- 2* for some positive integer k. can you devise a serial algo- n elements. which is storing one of the x_is. rithm and a parallelization of the serial algorithm so that the parallel algorithm requires only k communication phases? d. mpi provides a collective communication function, mpi. scan, that can be used to compute prefix sums: int mpi. scan( void void sendbuf p in */. recvbuf-p out/. count / in mpi datatype datatypein */, mp iop mp icomm / in comm it operates on arrays with count elements; both sendbuf. p and recvbufp should refer to blocks of count elements of type datatype. the op argu- ment is the same as op for mpi-reduce. write an mpi program that generates a random array of count elements on each mpi process, finds the prefix sums, and prints the results.

3. bob is arguing that if you use output feedback (ofb) mode twice in a row to encrypt a long message, m, using the same key each time, it will be more secure. explain why bob is wrong, no matter what encryption algorithm he is using for block encryption (15 points).
