- Apr 2, 2026 Amdahl and Gustafson Bounds in Capacity Models Why a serial fraction caps the throughput a fixed workload can reach, how scaled workload changes the bound, and what the usable-scalability limit means for sizing a fleet. performance engineering
- Feb 24, 2026 Sort-Last Compositing and the Depth Order Across Ranks How independently rendered partial images are merged into one correct image, why binary-tree compositing beats direct all-to-all, and where blending order and depth precision break the result. scientific computing
- 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
- Apr 28, 2025 Hierarchical Heartbeat Aggregation and the Cost of Intermediate Levels Why a tree of monitors cuts liveness traffic from quadratic to linear, what the extra level adds to detection time, and how the aggregate view loses the identity of the observer. distributed systems
- Apr 26, 2025 Contention Ceilings and the Limits of Parallel Scaling Why adding workers to a shared counter, lock, or cache line stops helping, how the serial fraction bounds speedup, and which designs remove the ceiling instead of raising it. backend systems
- Apr 2, 2024 The Universal Scalability Law: Why Throughput Peaks and Then Falls How contention and coherency terms extend Amdahl's bound into a curve that predicts a maximum, what retrograde scaling looks like, and how to fit the two parameters from measurements. performance engineering
