--------------------------------------------------------------------------------

. All users should note that the /work filesystem is unbacked-up scratch space
  and should always be considered to be "at risk". Only /home filespace is
  subject to a backup policy.

. It should be noted that /tmp filesystems are regularly purged and should
  not be used by users for the storing of any data. All files on /tmp are
  at permanent risk from being deleted without warning.

. Users must not initiate "ssh" login sessions to other machines (or to other
  login nodes) from the login nodes. Any such sessions are liable for
  termination.

. Serial batch queues - these should be used for large compilations, lengthy
  external file transfers, or any other activity that would otherwise make
  significant use of "interactive" resources on login nodes.

. Users must not leave backgrounded scripts running on login nodes. Any
  processes running that are disconnected from a tty are liable for termination.

. The max no of jobs that a user may submit to a regular queue is 8.
  Jobs in excess of that number are liable to be held

. The max no of jobs that a user may submit to the "low priority" queue is 2.
  Jobs in excess of that number are liable to be removed

  Please address all queries to "support@hector.ac.uk"

. Note: USE OF A LOGIN SESSION BY ANY PERSON OTHER THAN THE REGISTERED ACCOUNT
        HOLDER IS CONTRARY TO THE TERMS AND CONDITIONS OF USE AND IS UNLAWFUL

        NO USER MAY USE "SU" TO ACCESS THE ACCOUNT OF ANOTHER, OR ALLOW THEIR
        ACCOUNT TO BE USED BY ANOTHER USER TO "SU" TO THAT USER'S ACCOUNT
