Abstract:
Main memory is a critical resource in data centers, due to its major impact on application performance and server costs. However, Linux’s memory management system, designed to be general-purpose, is not always optimal for diverse workload requirements. We introduce USM, a framework for the rapid development of memory management policies in Linux. USM adopts a microkernel-inspired design, enabling MM policies to run in userspace. We demonstrate the flexibility of USM by implementing a variety of MM policies, and evaluate its performance against state-of-the-art solutions.
