ALCF: Theta

Running Jobs on Theta at ALCF

Once you have an allocation on Theta, or if you are using an existing allocation, you can reference the Onboarding Guide for answers to most of your questions about how to get started.

To login to Theta from a terminal:

ssh <username>@theta.alcf.anl.gov

At the prompt to enter your password, you must then enter your 4-digit PIN (given to you by ALCF when you get an account) followed immediately by the one-time 8-digit cryptocard password with no spaces in between the two. You are then in your home directory /home/<username> running on a login node. Login nodes run SUSE Enterprise Linux-based full CLE OS. There are two filesystems on Theta: the GPFS system which houses the /home directories in /gpfs/mira-home) and the Lustre filesystem which houses the /project directories in /lus/theta-fs0/projects. The /home directories are backed up and by default are 50GiB. The /project directories are NOT backed up and are by default 1TiB.
