Role of the login nodes
=======================


The Hoffman2 login nodes provide command line access to the Hoffman2 Cluster. 

The login nodes are meant for light-weight tasks such as submitting jobs and file operations (editing, copying). Any cpu-intensive or memory-intensive task, including compiling large programs, must be done either by batch job submission or in an interactive session on the compute nodes. See Running a Batch Job or How to Get an Interactive Session through UGE for more information.

Any process on the login nodes which seriously degrades other users’ use of the system may be terminated without prior notice by the System Administrator. Repeat offenders will have their accounts locked.
