Hello,


About parallelism and about Gustafson’s Law..

I am a white arab, and i think i am smart, so today
i will talk more about parallelism and about Gustafson’s Law:

Gustafson’s Law:

• If you increase the amount of work done by each parallel
task then the serial component will not dominate
• Increase the problem size to maintain scaling
• Can do this by adding extra complexity or increasing the overall
problem size

Scaling is important, as the more a code scales the larger a machine it
can take advantage of:

• can consider weak and strong scaling
• in practice, overheads limit the scalability of real parallel programs
• Amdahl’s law models these in terms of serial and parallel fractions
• larger problems generally scale better: Gustafson’s law

Load balance is also a crucial factor.

So read my following thoughts about the Threadpool to notice that my Threadpool that scales very well does Load balance well:
