20230705 / infiniband Cascade (S01E02)

I'm putting down Infiniband network on Cascade cluster (including scratches) for maintenance and debugging purposes.

EDIT 10:15: everything Cascade back online (QM8700 ↔ QM8790…).

: /scratch/Cascade is 98% full, please cleanup, or I'll do it…

kind reminder about scratches usage → http://www.ens-lyon.fr/PSMN/Documentation/filesystems/scratch.html
