Assume an algorithm takes 5.6 seconds to execute on a single 1.9 GHz processor. 20% of the algorithm is sequential. Assume that there is zero latency and that the remaining code exhibits perfect parallelism. How long (in seconds) should the algorithm take to execute on a parallel machine made of 3 1.9 GHz processors?
