1b. Quick Start (externally from a personal device)

Please note: as of Thursday 19th December 2024, offsite/external password-based SSH authentication is not possible on the head node servers. Logging in from a Doc Lab PC works as before. Please visit the Shell Server guide on how to set up public / private key authentication (you must be onsite at Imperial in order to create SSH keys for external remote access)

If connecting from your own personal computer or device, make sure you have set up your SSH keys, it is important to NOT prepend your username, SSH keys only or pre-authentication from a lab PC:

ssh gpucluster2.doc.ic.ac.uk
sbatch /vol/bitbucket/shared/slurmseg.sh

gpucluster2.doc.ic.ac.uk and gpucluster3.doc.ic.ac.uk are accessible from outside the college network, but if for some reason they are not accessible, use shell[1-5].doc.ic.ac.uk as a JumpHost:

ssh -J shell5.doc.ic.ac.uk gpucluster2.doc.ic.ac.uk

Again, find the slurm-xyz.out file in your '~/' home directory (or in the directory from which you ran the sbatch command)
