Big Memory Systems

Designed for professionals with operating systems fundamentals, this book bridges cutting-edge research with practical implementation, where big memory's unique characteristics (persistence at DRAM speeds, massive capacity, and fine-grained access) demand fundamentally new architectural approaches. Learn how to achieve faster queries with learned indexes in the disaggregated memory, how to optimize cuckoo hashing for persistent memory's asymmetric costs, and why the latest GPUs incorporate these persistence techniques. This book also provides efficient and useful toolkits: the RDMA protocols have been adopted in storage tiers, while the lock-free designs improve real-time recommendation systems. Whether building cloud-native databases, low-latency recommendation systems, or memory-driven AI services, these solutions will help exploit the full potential of the big memory.
