Clusters/Barbora NG

Hardware Overview

Work in progress

Barbora NG documentation is a WIP. The documentation is still being developed (reflecting changes in technical specifications) and may be updated frequently.

The launch of Barbora NG is planned for October/November. In the meantime, the first computational resources have already been allocated in the latest Open Access Grant Competition.

Barbora NG consists of 141 non-accelerated compute nodes named cn[001-141]. Each node is a powerful x86-64 computer equipped with 192 cores (2x Intel Xeon 6952P with 96 CPU cores) and 768 GB RAM. User access to the Barbora NG cluster is provided by two login nodes login[1-2]. The nodes are interlinked through high speed InfiniBand NDR and Ethernet networks.

The parameters are summarized in the following tables:
