Interactive RStudio using Open On Demand

To access RStudio on the University of Kentucky's high-performance computing (HPC) resources, please follow these steps:

1. Access Open OnDemand:

   • Navigate to LCC: http://ood.ccs.uky.edu / MCC: http://mcc-ood.ccs.uky.edu

2. Launch RStudio:

   • Click on the "Interactive Apps" tab.

   • Select "RStudio" from the dropdown menu.

   • Fill in the required details for your SLURM allocation, including:

     • Number of cores

     • Duration (in hours)

     • Partition

   • Click the "Launch" button.

3. Wait for Session Initialization:

   • The session may take a moment to start, especially during peak times. If the cluster is busy, you might experience a wait.

4. Release Resources After Use:

   • Once your session is complete, please ensure you properly end it to free up resources for other users.

Recommendation:

While RStudio is available for interactive use, it's generally advisable to develop your code on your local workstation. Once your code is ready, you can submit it as batch jobs using the SLURM scheduler via the command line. This approach optimizes resource utilization and aligns with best practices for HPC environments.
