Assume a program requires t $=100$ s of execution time on one processor. When run p processors, each processor requires t$/$p s$,$ as well as an additional $4$ s of overhead, irrespective of the number of processors. Compute the per$-$processor execution time for $2,4,8,16,32,64,$ and $128$ processors. For each case, list the corresponding speedup relative to a single processor and the ratio between actual speedup versus ideal speedup $($speedup if there was no overhead$)$
