Apex serves as the login node to the rest of machines in jungle. Connect to it
by accessing `ssflogin.bsc.es`, only from the apex you will be able to see other
machines.

Use `sinfo` to see which nodes are available and `salloc` to request them (see
the manual for more details). Avoid doing large builds or computations in apex,
use a different node instead.

The home is mounted from a hardware RAID 5 of 4 disks, and is shared across
other machines.
