Which speed up could be achieved according to Amdahl's Law for infinte number of processes if $5\%$ of a program is sequential and the remaining part is ideally parallel?

1. Infinite
2. $5$
3. $20$
4. $50$

sir no question
yes, I just created the format. Questions are to be added.

20. Is the obvious answer 1/.05

C:20

Speedup according to Amdahl's law is found as :

Speedup   =    1 / [ 1 - f1 - f2  + ..  +( f1 / S1) + ( f2/S2)  + ( f3/S3) .. ]

where f1 , f2 etc.  : fraction of enhancements

S1 , S2 etc : Speedup corresponding to each fraction of enhancement

Here in question f=0.95

1-f=5%=0.05 and s=⚮

Then speedup=1/(0.05+(0.95/⚮))

=1/(0.05+0)=20
