An application program is executed on a four-computer cluster. A benchmark program took time T on this cluster. Further, it was found that 80% of T was time in which the application was running simultaneously on all 4 computers. The remaining time, the application had to run on a single computer.

Calculate the effective speedup under the aforementioned condition as compared with executing the program on a single computer. Also calculate alpha, the percentage of code that has been parallelized (Programmed or Compiled so as to use the cluster mode) in the preceding program
