Setup¶

Computing¶

This tutorial runs on the ap23.uc.osg-htc.org host, which is an OSG-managed host. The Open Science Grid (OSG) is a worldwide grid of computing resources for scientific research.

ap23 uses ssh keys for passwordless login, and it uses Google Authenticator for 2-factor authentication.

>>> ssh your_unix_username@ap23.uc.osg-htc.org
(ap23.uc.osg-htc.org) Verification code:

ap23 runs the AlmaLinux9 operating system:

[ap23 ~]$ head /etc/os-release -n 2
NAME="AlmaLinux"
VERSION="9.4 (Seafoam Ocelot)"

Users have a home space /home/${USER} and a scratch space /scratch/${USER}, where ${USER} is the username of your computing account. There is also a high-capacity storage system /ospool/uc-shared, which is for storing large datasets and sharing files via the internet.

If you're familiar with the login.snowmass21.io host, you may be interested in FutureCollider Migration info.

Reference files¶

Each stage of the tutorial produces output that is used as input for the subsequent stages. In case it's helpful, output files of each stage have been prepared, which can be copied from:

/ospool/uc-shared/project/muoncollider/tutorial2024/checkpoints/

Tutorial area¶

This tutorial will run in the scratch space on ap23. Please create a new directory and go there:

mkdir /scratch/$USER/tutorial2024
cd /scratch/$USER/tutorial2024
