Scheduled

In order to get our new WEKA filesystems up to their best possible performance we need to dedicate some cores on each compute node for exclusive use by WEKA. So on Milan nodes Slurm jobs will only be able to use 126 cores per node rather than 128, and on Genoa nodes 166 rather than 168.
This change has already begun, having already been applied to all of the Milan nodes and the majority of the Genoa nodes. We expect to be doing the last of the Genoa nodes on September 8th.
