CPU Cache-Line

In the world of multi-core processors, managing concurrent access to data structures is crucial for efficient performance. But frequent updates can trigger a hidden bottleneck: cache coherence traffic. This traffic arises when one core modifies the data another core has cached, forcing updates and invalidation across the system. This article dives into a clever solution: the Cache-Line Hash Table (CLHT). CLHTs are specifically designed to minimize this cache coherence traffic, boosting the speed of concurrent data access.
