Through JupyterHub we provide interactive access to compute resources using JupyterLab. "JupyterLab is the latest web-based interactive development environment for notebooks, code, and data." There are a number of preconfigured notebooks for using software packages such as TensorFlow, PyROOT, and Spark. Team-specific notebooks are also available, creating a common environment for groups of users.
Getting Access
Account Requirements
- JLab CUE account
- Be a member of the ifarmusers unix netgroup
- Have an account in Slurm (our computing batch system)
To verify you meet these requirements, you can login into an ifarm machine and run:
% sacctmgr list users <username>Access to ifarm validates requirements 1 and 2. Being listed by sacctmgr will validate requirement 3.
Setting up your one-time password (OTP)
Go to https://jupyterhub.jlab.org and login with your JLab CUE username/password. The first time you do this, you will be presented with a QR code for establishing a OTP token. You can use Microsoft Authenticator, Google Authenticator, etc.
Not getting a QR code or need it reset? See this article.
Spawn a Job
Once logged in, you will be able to select a preconfigured notebook along with some compute specifications (ex. do you need a GPU?). If you experience issues, check out Common Issues.
