Question

Assuming you can use infinite number of CPUS for performance improvements, what would be the maximum speed up when the parallelizable portion is 95% of total execution time? i.2 ii.4 iii.10 iv.20

Answer 1

correct option is D i.e. 20

Step-by-step explanation:

Given data:

Parallelizable portion is given as 95%

so remaining will be serial portion i.e. 5%

we know that, for infinite number of cpus, maximum speed is calculated as

`v =(1)/(f)`

where f denote serial portion = 5% = 0.05

`v = (1)/(0.05)`

v = 20

hence so for serial portion of 5%, maximum speed is 20

correct option is D i.e. 20
