Session 2.2 Hardware Overview

Date: Monday, August 1, 2022

Andreas Goetz (agoetz at sdsc.edu)

All users of advanced CI can benefit from a basic understanding of hardware, to determine which factors affect application performance. Here we give an overview starting from CPUs (processors, cores, hyperthreading, instruction sets), the anatomy of a compute node (sockets, memory, attached devices, accelerators), to an overview of cluster architecture (login and compute nodes, interconnects). We also cover how to obtain hardware information using Linux tools, pseudo-filesystems and commonly used hardware utilization monitoring tools.
