Solstorm is not set up with batch-job queuing or accounting, and as such is based on the fair usage principle.
Usage policy for login-node
The login node is provided for users to access Solstorm. It is intended for users to setup and submit jobs, access results from jobs, transfer data to/from the cluster, compiling code, installing software, editing and managing files, etc. As a courtesy to your fellow users, you should refrain from doing anything long running or computationally intensive on this node as it will interfere with the ability of others to use Solstorm. Computationally intensive tasks should be submitted to the compute nodes, as that is what compute nodes are for.
Usage policy for compute nodes
The compute nodes are the work-horse of Solstorm. It is intended for users to run computationally intensive tasks. As a courtesy to your fellow users, you should refrain from interfering with other user’s computation by launching jobs on occupied nodes.
Before a compute-job is started, check if the intended compute-node is not busy with other jobs. You can find the status of a compute-node by:
- Check the status-page
- Run # gstat -a
- Run # top on compute-node
Usage policy for data storage
Solstorm provides storage in three flavours, home, personal work area and shared project area. This storage is not intended for long term storage, but transient for each job/project.
/home/<username> is intended for storing scripts, programs and results from jobs. This area is not for storing large data-files or similar.
/storage/user/<username> is intended for files used in computational activities. Files in this area are supposed to be transient, as in deleted as soon as computation is done.
/storage/project/<projectname> is intended for files used in computational activities and shared project files, scripts and results.
Special Policy for master-students:
- No user/group are allowed to occupy more than 5 nodes at the same time.
- Not allowed to use nodes compute-4-50 -> compute-4-58 and compute-6-*. These compute-nodes are reserved.
- Do not launch compute-jobs on occupied nodes.
Breach of these rules might lead to disabled accounts for the user/group.
