AIFM - High-Performance, Application-Integrated Far Memory

Explore a groundbreaking approach to memory management in datacenter servers through this 20-minute conference talk from OSDI '20. Dive into the concept of Application-Integrated Far Memory (AIFM), a high-performance solution that addresses memory scarcity and underutilization in modern datacenters. Learn how AIFM enables applications to access remote memory resources with local RAM-like latency, avoiding read and write amplification issues common in paging-based systems. Discover the innovative API that allows developers to create remoteable, hybrid near/far memory data structures while maintaining transparency and ease of use. Examine the key insights behind AIFM's efficiency, including the exposure of application-level semantics to a high-performance runtime. Explore real-world applications of AIFM, including a web application frontend, NYC taxi data analytics, a memcached-like key-value cache, and Snappy compression. Compare AIFM's performance against state-of-the-art kernel-integrated, paging-based far memory systems, and understand its potential to revolutionize memory utilization in datacenter environments.
