Dear fimm cluster users:

We have recently added two extra login nodes (login2 and login3 ) to fimm.bccs.uib.no. Current login1 will be go under maintenance for short period of time,and will be added back eventually.

We kindly ask you to save your current work on login1 and log-off from login1 and relogin again, you will landed one of login2 or login3. When you do "ssh fimm" DNS server will pick login node according to round-robin scheduling.

Eventually we will have 3 login nodes on fimm(login1, login2,login3), all of them has identical hardware, you can ssh between login nodes.

We have done this to increase redundancy and uptime.

Let us know if this caused any problem for you.

We will have maintenance in machine room on 5th of
April. Electrician will work on power line in machine room which
requirers electricity to be switched off completely.

Therefor fimm.bccs.uib.no cluster and grunch server will be
shutdown for 3 hours. We have reserved cluster for maintenance which
means jobs submitted to cluster which can not be finished by that time
will not run, and jobs which is already running but will not be able to
finish by that time will be killed.

Maintenance will start from 09:00 AM in the morning. We would advice
you to save all your work on fimm.bccs.uib.no and
grunch.bccs.uib.no by that time.

We are sorry for inconvenience, and appreciate your understanding.

One of OSSes has crashed this night leaving /work-common unavailable.
We are working on to fix it ASAP.
