as in: Not parallel.
What percentage of the operation is carried out in a strictly sequential way,
with no parallel processing of any kind.
I want to calculate the theoretical speed increase per core/thread according to
Amdahl's Law, but I need to know what percentage of the operation is performed
serially.
S(N) = 1 / [ Ps + (1/n)Pp] => 1 / [Ps + (1/n)(1 - Ps)]
where N is the number of cores and Ps is the percentage of the operation that is
strictly serial.
