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: https://community.idera.com/developer-tools/general-development/f/getit-and-third-party/72018/about-the-threadpool Thank you, Amine Moulay Ramdane.
