[Nebula-users] Nebula down due to campus electrical work 2020-03-01

[Kent Engström]

Hi,

due to electrical work at our campus, there is a need to disconnect the
power to our computer room where Nebula is located. The electricians
have suggested that the work takes place on Sunday 2020-03-01, as they
will also need to cut power to offices.

After talking to Ole V, we have decided to take down Nebula at 10:00
CET. It should be up again before lunch or sooner, depending on if there
is any other system work we need to do at the same time.

Remember: as no jobs can be running when the system is down and we do
not want to kill running jobs on Sunday morning, the nodes will be
reserved during the downtime. That means that in the week before, you
need to use a suitably low timelimit (-t) for your job submissions if
you want them to start.

We will get back to you a week before 1 March to remind you.

Best Regards,
