NFS = network file system. allspice is our main file server, but we also use beet for snapshots and mango for /scratch.
Each lab machine has it's own /local partition. /scratch is really on mango, but mounted over the network to each lab machine. /scratch should look the same from any lab machine (just like your home dir).
If you have a long-running job that writes lots of data, try to write that data to a /local. It will be *much* faster than writing to /scratch.
/scratch and the /locals do not get backed up, so don't store any critical files on those partitions.

Every user has their own /scratch directory.

Users can create a directory on any /local. Each /local is different. /local on mace is smaller than /local on wasabi.
