Migration is over, we manage to take up Lustre filesystem with new MDS server. /shared and /work filesystem is mounted on cyclone.hpc.uib.no and grunch.hpc.uib.no. Hexagon is up and running again. Samba and NFS exports are also running on Leo.hpc.uib.no.

Update 12_11 15:00 :

Migration is still ongoing, we will keep you posted.

Update 02_11 09:30 :

Due to the delayed delivery of physical parts, we have to postpone our downtime to 12th November. Corresponding node reservation on the hexagon is also postponed to 12th November.

Thank you for your consideration!

Dear HPC User,

The metadata server for the /shared file system has to be replaced/upgraded and therefore it must be unmounted from all the clients.

This will result in scheduled downtime for Hexagon, Grunch and Cyclone machines. We start at 08:00 AM on the 5th of November and expect to be ready by the end of the working day.

Thank you for your consideration!

There is a scheduled downtime for Hexagon and /shared file system for Wednesday, 23rd of May. Scheduled downtime will start at 09:00 and we expect to have the systems back by 16:00, same day.

Our apologies for any inconvenience this downtime can give you.

  • This is a significant upgrade and some binaries are not compatible anymore, thus before opening support case please recompile your code.
  • Older compilers will have to use the following compiling recipe: 
    module swap cray-mpich cray-mpich2
    
module swap cray-libsci cray-libsci/12.2.0
    
module load craype-barcelona
  • Only current version of PGI will work without using the above mentioned recipe.
  • xt prefixed modules are deprecated and replaced by cray prefixed modules.
    ex: 
    xtpe-interlagos

    - replaced by

    craype-interlagos
  • Cray CCE is not working currently because of missing license. We are in contact with the vendor.
