For those having problems with the system openmpi and OpenCL ICD, use E5 foss or gompi OpenMPI suite:

ml use /applis/PSMN/debian11/E5/modules/all
# then
ml load gompi/2021b
# or
ml load foss/2021b

then rebuild your binaries.

Happy Holydays. LT signing off.

Something is broken or hang in our networking. We are working on it.

EDIT 11:19 - I still don't now precisely what happened, but every login node, visu node and compute node need a reboot.

EDIT 11:40 - @login OK, @visu OK

reboot of compute nodes ongoing, every running jobs will be lost.

EDIT 14:30 - @compute is restarting

EDIT 15h00 - @compute is fully restarted

We may have to deal with extrem mesures in the next few weeks/months, including :

• half, or all, of computing powered off,
• complete power outages, including storage, with J-1 warnings,
• 9 hours a day of job suspension.

This is due to electricity prices and possible power outages.

Situation is still very fluid, decisions have not been made yet.

“Hope for the best, but prepare for the worst.”

A storage node for /scratch/Cral is having issues. This result in a partial unavailability (not loss) of data.
