There's no explicit way.
1. Check the cluster documentation written by the cluster admins
2. Ask the cluster admins
3. Run "mount" or "cat /etc/mtab" or "df -H" on the master node and check
against the same commands on a worker node (by getting an interactive
terminal: "srun --pty bash" )

creative agents who can shape our destinies. Apocalyptic civics is the
conviction that the only way out is through, and the only way through is
together. "
