Amdahl's Law states that the speedup from parallelization is limited by the proportion of the task that cannot be parallelized; if 80% of the work can be parallelized, the theoretical maximum speedup is only 5×.

UnverifiedAmdahl's law states that system speedup is limited by the portion that cannot be parallelized, and end-to-end speedup is not equivalent to single-step computation speedup.77% similarUnverifiedAmdahl's law provides the intuition: overall speedup is limited by the proportion that cannot be parallelized.77% similarUnverifiedThe O(1/√N) convergence rate cannot be further improved in the sense of rates, representing that risk estimation has reached the information-theoretically optimal rate.65% similarUnverifiedThe cost of the fan-out/merge pattern is that the merge step usually needs to wait for the slowest subtask, so how uniform the task granularity is directly affects overall efficiency.64% similarUnverifiedAmdahl定律由Gene Amdahl在1967年提出，描述如果程序中只有P比例可被加速则整体加速比不超过1/(1-P)64% similar
