n this problem, you are asked to decide between two alternatives in speeding up a given program P by

running parts of it in parallel on different machines. In alternative A$,$ half the program can run parallel on a

machine with $4-$cores. In alternative B$,25\%$ of the program can run in parallel on a machine with $32-$cores.

Which alternative provides a higher bound on the possible speed$-$up obtained in executing the program
