Answer:
The speed up gain for this applications is 2.5.
Explanation:
The time to execute the program in one processor is:
10(serial) + 90 = 100s
In the parallel execution, the parallel time(90) is divided by the number of processors, that is 30. So
10 + 90/3 = 10 + 30 = 40s.
The speed-up gain is the division of the time of the serial execution by the time of the parallel execution.
So 100/40 = 2.5
The speed up gain for this applications is 2.5.
