Introduction + +This document outlines the requirements for the *Java Thread Affinity* library. The primary purpose of this library is to provide Java applications with the capability to control Central Processing Unit (CPU) affinity for their threads. This allows developers to bind specific threads to designated CPU cores, which can lead to performance improvements, especially in latency-sensitive applications, by reducing context switching and improving cache utilisation. + +The library aims to offer a cross-platform API, with the most comprehensive support for Linux systems, leveraging Java Native Access (JNA) and, where applicable, Java Native Interface (JNI) for low-level system interactions. + +== 2. Scope + +The scope of the Java Thread Affinity project includes: + +* Providing mechanisms to get and set thread affinity on supported operating systems. +* Offering a CPU locking mechanism (`AffinityLock`) to manage core reservations for threads or entire cores. +* Detecting or allowing specification of the CPU layout (sockets, cores, threads per core). +* Providing a high-resolution timer. +* Supporting inter-process lock checking for CPU core reservations. +* Delivering a thread factory that assigns affinity to newly created threads. +* Packaging the core library and an OSGi-compatible test bundle. + +== 3.
