The servers are called nodes. HPC clusters use batch systems for running compute jobs. Interactive access is usually limited to a few nodes. A typical cluster contains of these parts: text/html 2022-10-21T09:19:48+00:00 kunkel (kunkel@undisclosed.example.com) https://www.hpc-certification.org/wiki/skill-tree/use/2/b?rev=1666336788&do=diff USE2 Running of Parallel Programs Parallel computers are operated differently than a normal PC, all users must share the system. Therefore, various operative procedures are in place. Users must understand these concepts and procedures to be able to use the available resources of a system to run a parallel application. Moreover, individual solutions can often be found in a specific system. text/html 2022-10-10T14:59:29+00:00 agerbes (agerbes@undisclosed.example.com) https://www.hpc-certification.org/wiki/skill-tree/adm/1/4/1/2/b?rev=1665406769&do=diff ADM1.4.1.2-B Deploy stateless images Maintainer: Markus Hilger, Peter Grossöhme, HPC Engineers @ Megware Background To minimise costs and downtime, many HPC compute nodes do not have local disks, but only keep the operating system in RAM. This type of deployment requires special tools to create an image that can be loaded into the RAM of a compute node. text/html 2022-10-10T14:59:20+00:00 agerbes (agerbes@undisclosed.example.com) https://www.hpc-certification.org/wiki/skill-tree/adm/1/4/1/1/b?rev=1665406760&do=diff ADM1.4.1.1-B Deploy stateful images Maintainer: Markus Hilger, Peter Grossöhme, HPC Engineers @ Megware Background An HPC cluster consists of several central components such as storage, workload manager, subnet manager, etc., which sometimes run on dedicated servers. These servers must be deployed from the central management system. Usually these servers have local hard disks, so a stateful installation of these servers is necessary. text/html 2022-10-10T14:41:29+00:00 agerbes (agerbes@undisclosed.example.com) https://www.hpc-certification.org/wiki/skill-tree/adm/3/1/1/b?rev=1665405689&do=diff ADM3.1.1-B xCAT Maintainer: Markus Hilger, Peter Grossöhme, HPC Engineers @ Megware Background Aim Outcomes Subskills * ADM1.4-B Software Stack text/html 2022-10-10T14:40:34+00:00 agerbes (agerbes@undisclosed.example.com) https://www.hpc-certification.org/wiki/skill-tree/adm/1/4/1/3/b?rev=1665405634&do=diff ADM1.4.1.3-B Manage cluster nodes Maintainer: Markus Hilger, Peter Grossöhme, HPC Engineers @ Megware Background During the operation of an HPC cluster, it is necessary to manually execute commands on several nodes or make temporary changes to the configuration for debugging or testing purposes. In case of problems, any logs or measurements must be collected. Furthermore, regular software updates are necessary.
