What is Amdahl’s Law?The performance improvement gained by optimizing one part of a system is limited by the fraction of time that the improved part is used.
Amdahl’s Law states that “the overall performance improvement gained by optimizing a single part of a system is limited by the fraction of time that the improved part is actually used.” In layman’s terms, we can think of this as a chain only being as strong as its weakest link.
For high performance computing (HPC), that weak link turns out to be the communication among processors and between nodes (collections of processors). Calculations are made, then things pause while those calculations are passed between parts of the computing system before more calculations can be made.
