Effectively Prefetching Remote Memory with Leap

Effectively Prefetching Remote Memory with Leap

Explore a conference talk from USENIX ATC '20 that introduces Leap, an innovative prefetching solution for remote memory accesses in memory disaggregation systems. Learn how Leap employs an online, majority-based prefetching algorithm to increase page cache hit rates and implements a lightweight, efficient data path in the kernel to mitigate latency bottlenecks. Discover how this approach significantly improves median and tail remote page access latencies for memory-bound applications, leading to substantial performance enhancements compared to state-of-the-art solutions. Gain insights into the challenges of memory disaggregation over RDMA and how Leap addresses them to optimize application performance in memory-constrained environments.
