Overview
MATLAB can be run interactively on SeaWulf through the Open OnDemand (OOD) portal. This allows you to use MATLAB’s graphical interface and computational capabilities from a web browser without requiring a local MATLAB installation.
Getting Started
- Open the SeaWulf Open OnDemand portal: https://sn-ood.seawulf.stonybrook.edu/
- Log in using your NetID and DUO authentication.
- From the dashboard, select Interactive Apps and choose MATLAB.
- Select the compute queue and number of cores suitable for your computation.
- Click Launch. Once the session starts, MATLAB will open in your browser.
Best Practices
- Save your scripts and data frequently to your home or project directory.
- Use the appropriate node type for your workload: 28-core Haswell, 40-core Skylake, 96-core Milan, or 96-core Xeon Max HBM.
- Close sessions when finished to free up cluster resources.
- Install additional MATLAB toolboxes in your home or project space if needed and ensure paths are configured correctly.
- Monitor resource usage for memory-intensive tasks to prevent job termination.
Accessing Files
You can read and write files directly from your home, scratch, or project directories in MATLAB. Use relative paths or mounted directories to organize your workflows efficiently.
Tip: For reproducible workflows, save MATLAB projects in your project space and use version control when collaborating with others.
