Teramem System for Applications with Extreme Memory Requirements
The node teramem2 is a single node with 6 TBytes main memory. It is part of the normal Linux Cluster infrastructure at LRZ which means that users can access their $HOME and $PROJECT directories as on every other node in the cluster. However, its mode of operation slightly differs from the remaining cluster nodes which can only be used in batch mode. As the teramem2 is the only system at LRZ, which can currently satisfy memory requirements beyond 1 TByte in a single node, users can choose between using the system in batch or interactive mode depending on their specific needs. Both options are described below.
