-The Barbora cluster consists of 201 computational nodes named **cn[001-201]** 
+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 192 GB of RAM.
-User access to the Barbora cluster is provided by two login nodes **login[1,2]**.
