- Feb 20, 2026 Amdahl's Law and the Serial Fraction That Caps Speedup Why a fixed serial portion of a workload bounds speedup no matter how many processors are added, how to estimate that fraction, and where the law stops describing real scaling. performance engineering
- Nov 28, 2024 Amdahl, Gustafson, and the Fixed-Problem Fallacy Why the two scaling laws disagree, which quantity each holds constant, and how the choice of fixed time versus fixed problem size changes the predicted ceiling. algorithms
