Hardware of the cluster

Hardware

The Linux cluster is operated under the CentOS 7 operating system. The IBM General Parallel File System GPFS is used as the globally available file system. The GPFS data is accessed via three file servers, each of which is connected to the Linux cluster at 1 Gbps. SMT features such as "Hyper-Threading" are deactivated on all servers.

The hardware of the cluster is divided into a public area, whose nodes can be used by anyone with a user account at the University of Kassel, and nodes in partitions, which are moderated by the department or subject area to which they belong.
