The Barbora cluster consists of 201 computational nodes named **cn[001-201]** of which 192 are regular compute nodes, 8 are GPU Tesla V100 accelerated nodes and 1 is a fat node. Each node is a powerful x86-64 computer, equipped with 36/24/128 cores (18-core Intel Cascade Lake 6240 / 12-core Intel Skylake Gold 6126 / 16-core Intel Skylake 8153), at least 192GB of RAM. User access to the Barbora cluster is provided by two login nodes **login[1,2]**. The nodes are interlinked through high speed InfiniBand and Ethernet networks.
