Supercomputers

• All users of IDSC supercomputers are required to have an IDSC account.

• All SSH sessions are closed automatically after 30 minutes of inactivity.

• No backups are performed on cluster file systems.

• IDSC does not alter user files.

• Jobs running on clusters may be terminated for:

  • using excessive resources or exceeding 30 minutes of CPU time on login nodes

  • failing to reserve appropriate LSF resources

  • backgrounding LSF processes with the & operator

  • running on inappropriate LSF queues

  • running from data on /nethome

  The IDSC account responsible for those jobs may be suspended.

• Users with disabled IDSC accounts must submit a request here for temporary account reactivation.

Allocations

• Active cluster users are allocated a logical home directory area on the cluster, PEGASUS: /nethome/username, TRITON: /home/username , limited to 250GB.

• Active projects can be allocated scratch directories: PEGASUS: /scratch/projects/projectID, TRITON: /scratch/projects/projectID, intended for compiles and run-time input & output files.

• Disk allocations are only for data currently being processed.

• Data for running jobs must be staged exclusively in the /scratch file system. IDSC accounts staging job data in the /nethome filesystem may be suspended.

• Both home and scratch are available on all nodes in their respective clusters.

• Accounts exceeding the 250GB home limit will be suspended. Once usage is under 250GB, the account will be enabled.

• Data on /scratch may be purged after 21 days if necessary to maintain adaquate space for all accounts.

• For both the above exceeded allocation scenarios, a member of IDSC will send a notification before this occurs. This will give you the opporutnity to move your data if needed.

Software

• Users are free to install software in their home directories on IDSC clusters. More information about installing software onto ACS systems on ReadTheDocs : https://acs-docs.readthedocs.io/

• Cluster software requests are reviewed quarterly. Global software packages are evaluated per request.

• Requests can be made here.
