Cache, Prefetching, False Sharing, Pipeline and Data Dependency: Performance Optimization in Rust

The article uses Rust benchmarks to show how cache layout, prefetching, associativity, false sharing, pipeline stalls, and loop data dependencies impact performance, and demonstrates practical optimizations such as row‑major traversal, proper alignment, avoiding dependent loops, and leveraging sequential access to achieve near‑optimal speed.

Cache, Prefetching, False Sharing, Pipeline, and Data Dependency: Benchmarks and Optimizations in Rust

The article shows how row‑major vs column‑major traversal, random access, cache‑set conflicts, false sharing, branch‑prediction failures, and loop‑carried data dependencies each degrade performance by tying Rust (and C++) code patterns to CPU cache behavior, prefetching, pipeline stalls, and vectorization limits, demonstrated through runnable benchmarks.

Upgrade of Dependency Model in Bilibili Data Platform

Bilibili’s data platform upgraded its dependency model by shifting from project‑level to task‑level dependencies, adding root and end nodes, using virtual tasks for external data, introducing offset handling, implementing an abstract DependencySubject and asynchronous callbacks, achieving sub‑second latency for tens of thousands of daily tasks while planning automated lineage and richer rule support.
