Abstract:Summary
Cache coherence in modern computer architectures enables easier programming by sharing data across multiple processors. Unfortunately, it can also limit scalability due to cache coherency traffic initiated by competing memory accesses. Rack‐scale systems introduce shared memory across a whole rack, but without inter‐node cache coherence. This poses memory management and concurrency control challenges for applications that must explicitly manage cache‐lines. To fully utilize rack‐scale systems for low‐l… Show more
