====== 20230704 / infiniband Cascade (scratch, MPI...) ======

We are "hot-"modifying the InfiniBand network of Cascade cluster. You may experience some temporarly access problems on Cascade scratches.

''/scratch/Cascade'' is **99% full**, hence performing as badly as possible (it's even not performing at all, for now).
**You should have cleanup while you can, because now, I'm in charge...**: Erasing all files & directory older than 180 days (that's **six months old**) on ''/scratch/Cascade''. 
Do NOT complain, documentation is crystal-clear (http://www.ens-lyon.fr/PSMN/Documentation/filesystems/scratch.html)

**EDIT 17:00**: due to a misconfiguration we cannot find, half of scratch nodes (Cascade and Cral) are not connected anymore.
