Please explain how to do this problem. Thanks.
An algorithm takes 7.8 seconds to execute on a single 2.6 GHz processor. 54% 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 8 2.6 GHz processors? Round answers to one decimal place.
