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

COMPLECS (COMPrehensive Learning for end-users to Effectively utilize CyberinfraStructure) is a new SDSC program where training will cover non-programming skills needed to effectively use supercomputers. Topics include parallel computing concepts, Linux tools and bash scripting, security, batch computing, how to get help, data management and interactive computing. Each session offers 1 hour of instruction followed by a 30-minute Q&A. COMPLECS is supported by NSF award 2320934.
