Interactive Applications for OnDemand on the UCSF C4 Cluster

This repository holds the configuration for the UCSF C4 OnDemand services. Open OnDemand provides access to high-performance-compute (HPC) resources via the web browser, e.g. a file management, a command-line shell, a graphical desktop environment, job scheduler management, and access popular graphical user interfaces (GUIs). The C4 OnDemand service, currently provides:

• bc_desktop - A MATE Desktop environment
• RStudio Server - Depends on the CBI software stack.
• Jupyter Notebook - Depends on a virtual environmeent that is installed on a shared file system.

These services are launched automatically via the C4 job scheduler and will run on a compute node that can meet the requests resource specifications.
