Hexagon: planned maintenance 18.10 – 19.10

Lóránd Szentannai • September 21, 2016

We will have a two day planned maintenance on hexagon starting on 18th of October 09:00.

During the maintenance we will carry out filesystem upgrade, firmware upgrades as well service the hardware.

The job submission system has reservation in place, thus jobs which are not able to finish before maintenance start, will not be started.

Update: 2016-10-18 09:35 Maintenance has started, slightly delayed due to traffic jam.

Update: 2016-10-19 12:00 Maintenance has been finished, Hexagon is up and accessible again.

Fimm cluster and Grunch server downtime

saerda • August 17, 2016

Dear Fimm cluster and Grunch server users:

Fimm cluster and grunch server will have downtime 25th August from 09:00 to 16:00.

During this downtime we will perform hardware firmware update, internal and external switch firmware update.

For Grunch server except hardware firmware update we will also enable quota on grunchfs.

We will also update slurm version to 16.05.4 on fimm.hpc.uib.no.

Both fimm.hpc.uib.no and grunch.bccs.uib.no will not be accessible during this downtime.

We will keep all process updated on this page.

Please contact hpc-support@hpc.uib.no if you have any questions.

26/08/2016 09:40 Update: Firmware update is done on internal and external switches. Slurm is updated on fimm.hpc.uib.no and Grunch firmware is also updated. Currently we are working on quota on grunchfs, which needs to scan whole file system, this will take some time before we can make gruncfs available for users on grunch server.

26/08/2016 10:40 Update: Grunch quota is enabled, and grunch server is online again.

Hexagon: PGI 16.05, CCE 8.5.1and CrayPat 6.4.1 are available

Alexander Oltu • August 10, 2016

PGI 16.05, CCE 8.5.1 and CrayPat 6.4.1 are installed on Hexagon as non default versions.

As the newer CCE and CrayPat installations are rather experimental, to access version 8.5.1 of the Cray compiler and 6.4.1 version of the CrayPat one needs to run:

module use /opt/cray/pe/modulefiles

NB. No extra steps are required to access PGI 16.05

/work-common storage capacity extended

Lóránd Szentannai • August 10, 2016

We have added additional 74TB storage capacity to /work-common.

Connection to Grunch server is down.

saerda • August 1, 2016

We lost one of our core internal switch this morning, unfortunately grunch is on this switch and lost connection to fimm and hexagon. Switch will be replaced early tomorrow hopefully. Meanwhile we will try to find different solution to resume connectivity.
