Dear users of cyclone and Ubuntu,
A large part of the data under
/Data/ is being migrated to the central
IT department storage place. To finish the migration, this Tursday
between 9:00 and 15:00 paths below
/Data/ won't be accessible all the
time (or at least not writable).
Hereafter, on both the Ubuntu clients and on cyclone, all your files are
still available under the regular
/Data/skd paths you're
On Windows the new locations will be as follows:
For your convenience, you can map each to a drive letter by following this HOWTO.
On the Wiki there is more detailed information on GFI & SKD Storage.
Feel free to contact us via hjelp.uib.no if you have any questions.
Update 28.05 : The data migration is finished and all Linux and Window paths with the new destinations should be accessible.

We are pleased to announce the course on the national HPC systems & NIRD Toolkit and a basic course on UNIX. More details are available on the course webpage at:
The course is free of charge and is on Zoom. Zoom link will be sent to all participants before the course.
The HPC course will be held between 27th -29th October (900-12:30) and the UNIX course between 19th &20th October (900-12:30).

Dear Cyclone and Grunch Users,
Our machine room at Thormøhlensgate 55 will have power outage during Friday 17 April 15:00 to Sunday 19. April 24:00.
There will be planned work to do maintenance for power line in the building.
Because of that maintenance, we have to take down all our servers at 15:00 Friday 17. April and hopefully we will take all servers online before 08:00 Monday 20. April.
cyclone and grunch server will be taken down and will not be accessible during this time.
/shared/ filesystem which is exported via leo.hpc.uib.no to the university campus will not be accessible during this time.
We advice all users to plan their work in good time to avoid unnecessary problems.
Update20:30_19.04.2020: Our downtime is over, cyclone and grunch is back online.
Please contact us via hjelp.uib.no
if you have any further questions.
Scientific computing team.
Cyclone will be taken down tomorrow, 25th September, from 12:00 until 14:00 for regular maintenance. We will perform OS related updates and some core libraries are going to be updated too.
more information will be posted.
Update 25.09.2019 14:55 cyclone.hpc.uib.no is back online.
During the last week, we have experienced a problem with leo.hpc.uib.no as our NFS server, it crashes due to Lustre bug triggered by NFS related unknown reason.
After some debugging, we have made some changes to our Lustre configuration, which looks promising so far.
leo.hpc.uib.no has been running without a problem for the last 2 days.
We will keep monitoring the system and will post here if anything else happens.
Please don't hesitate to contact us if you encounter any problem regarding NFS and samba exports from Leo.hpc.uib.no
We apologize for the inconvenience.
Update 10:40: Access to cyclone is reopened now. Delay was caused by missing kernel modules and old Lustre packages.
Cyclone will be sharply rebooted at 09:00 to apply new filesystem settings.
This morning /fimm filesystem crashed on fimm.hpc.uib.no. This caused /fimm and /work filesystem unaccessible for users and fimm login node hanged.
We are able to take it up back online quick, but we are investigating the cause of the problem.
Jobs that are running during the crash are all killed.
We are sorry fot inconvenience.
work file system on fimm crashed at 12:30, work was unmounted from most of the compute node, your job using work file system probably all crashed and you have to resubmit them.
We are investigating the issue and sorry for all inconvenience.
Due to a GPFS file system hang on the fimm frontend, for a short period of time (hopefully 10-15 minutes), the frontend will not be available, all users need to log in again after this.
Update, 10:12: fimm frontend needs to be rebooted to clear the hang.
Update, 10:26: fimm frontend is now rebooted and up again.
