The software environment has been updated with respect to Alvin and Frost, to be more like NSC's Tetralith and Sigma clusters for Swedish academic users. The cluster now runs CentOS 7 Linux, and the module system is slightly different: it is now based on Lmod, which has multiple hierarchies. NSC has also started installing software semi-automatically using the EasyBuild system (these modules are called
[modulename]-eb). NSC strives to keep the software environment and the available software installations as identical as possible on all clusters.
