In this post David J Morse from Dell asks himself questions with the goal to help certain customers who run a Linux variant on Dell PowerEdge servers. this support include : tools, resources they might need to examine their PowerEdge server and ensure optimal performance.

 Threfore some of his questions include: ‘’have you ever wondered how to determine what physical core mapped to a particular CPU in the Operating System?  How about the impact of Intel® Hyper-Threading Technology on Linux core enumeration?  Have you heard about NUMA (Non-Uniform Memory Access) capabilities in hardware and software, but never understood why it is valuable to ensure that workloads and memory are localized on a single NUMA node? How about the strange new world of NUMA I/O? ‘’

 

Via this whitepaper released and available, you will learn from the text and illustrations how common multi-socket platforms have their cores enumerated, as well as providing you with the utilities and knowledge you need to examine your own system and develop new best practices for optimal performance .
