A certain program consists of three independent parts A, B and C that can execute in parallel on separate processors within a multiprocessor system. None of the parts can be further subdivided and each part must execute on a single processor. Part A requires 78 billion cycles to complete, part B requires 40 billion cycles to complete and part C requires 62 billion cycles. The program is executed on an SMP system with 4 identical processors all running at the same 2 GHz clock rate. a) How long does it take to execute the entire program (all 3 parts) if only one of the processors is used to execute the program (the other 3 processors remain idle)?b) What is the minimum time required to execute the entire program (all 3 parts) if only two of the processors are used to execute the program (the other 2 processors remain idle)?c) What is the minimum time required to execute the entire program (all 3 parts) if all 4 processors are used?
