Keywords: Optimizing-different-parts.png Explanation Assume that a task has two independent parts A and B B takes roughly 25 of the time of the whole computation By working very hard one may be able to make this part 5 times faster but this only reduces the time for the whole computation by a little In contrast one may need to perform less work to make part A be twice as fast This will make the computation much faster than by optimizing part B even though B got a bigger speed-up 5x versus 2x <br /> explanation taken from caption in wikipedia Amdahl's law Optimizing-different-parts svg from en wikipedia Author FedericoMenaQuintero Amdahl's law |
