A parallel program runs for $2000$ seconds on $128$ processors. After careful investigation, we found that only $5$ seconds out of the $2000$ seconds were actually spent in redundant operations, and the rest of the code was fully parallelized. $($a$)$ What's the $$scaled$$ speedup of this program? $($b$)$ What is the efficiency of the program on $128$ processors? $($c$)$ What would be the sequential run time of this program?
