[Bi-users] Update: Bi/Accumulus downtime 28-29 March, may be extended to 30 March if needed

[Kent Engström]

Dear Bi and Accumulus Users,

an update about the planned downtime for Bi and Accumulus next week,
planned for Tuesday 28 March (from 08:00 CEST) - Wednesday 29 March.

Since we initially planned this, our facilities people have asked for a
slot to work on transformer/UPSes, and to avoid a separate Bi/Accumulus
downtime for that, we have slotted that into the schedule on Tuesday
morning. This *might* mean that we cannot complete all other work by the
end of Wednesday. In that case, the downtime will extend into Thursday
30 March. We will inform you on the Wednesday afternoon about the
current plans.

Please note:

- Compute nodes and login nodes will be unavailable during the downtime.

- Accumulus will be unavailable from Tetralith too during the downtime.

- The job queue will be emptied during the downtime due to the Slurm
  upgrade we will be doing.

- If you want jobs you submit before the downtime to be able to start,
  remember to adjust the timelimit so they can complete before Tuesday
  28 March at 08:00 CEST.

- Those of you who will be moved to a new primary group (for example
  sm_foum instead of sm_foup) will get an individual email about this.


Best Regards,
