| Question 22 |
A multi processor system with 16 processors is used to execute a parallelizable task. If the serial portion of the task takes 200 clock cycles and the parallel portion take 800 clock cycles. When all 16 processor are used how many total clock cycles are required to complete the task ?
| 250 | |
| 300 | |
| 400 | |
| 450 |
Question 22 Explanation:
The serial portion takes 200 clock cycles.
The parallel portion takes 800 clock cycles.
The number of processors=16
Total time=Serial portion+Parallel portion=200+800=1000 clock cycles.
Parallel time with 16 processors= 800/16=50 clock cycles
Total time with 16 processors=Serial time+Parallel time with 16 processors
Total time with 16 processors=200+50=250 clock cycles
The parallel portion takes 800 clock cycles.
The number of processors=16
Total time=Serial portion+Parallel portion=200+800=1000 clock cycles.
Parallel time with 16 processors= 800/16=50 clock cycles
Total time with 16 processors=Serial time+Parallel time with 16 processors
Total time with 16 processors=200+50=250 clock cycles
Correct Answer: A
