. 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 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.

. Maximum 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"

. Users are reminded that they should NOT initiate 'ssh' connections between
  the Phase2A and Phase2B systems. Such connections are liable for termination.
