Hardware transactional memory promised easy lock‑free programming, but a mix of hardware complexity, unpredictable performance, high silicon cost, and insufficient language and library support kept it from widespread adoption.
A deep dive into CPU branch prediction, speculative execution, and why mispredictions matter for performance and security.
A deep dive into why the structure of the memory hierarchy determines the real‑world latency of data accesses, illustrated with calculations and practical advice.
A deep dive into the cost of memory layers, showing how caches, RAM, and storage affect overall latency and how to model them accurately.
