. 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.
