CentOS as Qlustar edge platform
As one of the most popular Linux distributions, CentOS is also widely used on HPC clusters. To support the large CentOS user community, Qlustar integrates CentOS 7 and 8 as an edge platform. This means you can run CentOS on the compute nodes of a Qlustar cluster in the same way as running Ubuntu. Please note that CentOS on Qlustar is not endorsed by the CentOS project in any way.
Due to the annoncement that CentOS 8 will reach its End of Lifetime at the end of 2021, Qlustar will have to move to an alternative RHEL compatible distribution for replacement of CentOS 8 before that date. Which distribution will be chosen will be announced in time. For Qlustar users, this choice will be of secondary importance, since the corresponding changes are all under the hood and being taken care of by Qlustar developers. The move will involve no more effort than e.g. an update from CentOS 8.3 to 8.4.
The OpenHPC project adds many OS packages to enrich CentOS as an HPC platform with a goal to provide re-usable building blocks for the HPC community. Qlustar transparently integrates the OpenHPC software repository to allow the use of all OpenHPC packages on Qlustar clusters. Note, that the system related parts of OpenHPC (provisioning tools, resource manegement or I/O clients) are not needed on Qlustar since their functionality is already provided by Qlustar core. The rich collection of development tools and scientific libraries provided by OpenHPC makes the CentOS/OpenHPC combo a popular choice for HPC on Qlustar clusters.
