0x13 CPU Affinity & Cache

🇺🇸 English | 🇨🇳 中文

🇺🇸 English

📅 Status: 🚧 Planned Core Objective: Pin threads to CPU cores and optimize data layout for cache locality.

1. Overview

CPU Affinity: Bind matching threads to isolated cores to reduce context switching.
Cache Locality: Optimize OrderBook node layout to fit L1/L2 cache lines.
False Sharing: Padding atomic variables to prevent cache line contention.

📅 状态: 🚧 计划中 核心目标: 主要线程绑核与缓存友好性优化。

1. 概述

CPU 亲和性 (Affinity): 将撮合线程绑定到隔离核心，减少上下文切换。
缓存局部性 (Locality): 优化 OrderBook 节点布局以适应 L1/L2 缓存行。
伪共享 (False Sharing): 通过 Padding 避免多线程竞争同一缓存行。
