Performance analysis engineers know that NUMA can seriously impact performance and that NUMA performance analysis can be challenging. We've realized that currently there isn't an easy-to-use tool that lets us easily observe whether NUMA-related issues exist and, if so, where the NUMA bottleneck(s) reside. It can be quite challenging, especially in complex server environments. We decided to create a tool that automatically performs the typical steps in NUMA analysis and provides a good starting point to dive in and fix NUMA-related bottlenecks. That's NumaTOP! NumaTOP is an observation tool for runtime memory locality characterization and analysis of processes and threads running on a NUMA system. It helps the user characterize the NUMA behavior of processes and threads and identify where the NUMA-related performance bottlenecks reside. It uses Intel performance counter sampling technologies and associates the performance data with system runtime information to provide real-time analysis for production systems. NumaTOP is a GUI tool. It can run on Linux kernel 3.8 with a perf load latency patch today. That patch is planned to be integrated into kernel 3.9 or a later release.
