Thread Affinity and Core Isolation

Medium · concurrency · Quant Developer interview question · c++, concurrency, low-latency, systems

Thread Affinity or (CPU Pinning) is a critical optimization technique used to bind execution threads to specific CPU cores, thereby maximizing cache locality and minimizing context switching overhead. By preventing the operating system scheduler from migrating threads, developers can achieve deterministic performance essential for high-frequency trading strategies. This task involves implementing POSIX-compliant thread management to enforce these core isolation requirements. Task Implement the
