Matlab-Proxy in OOD

Getting Started​

You can run Matlab-Proxy in OOD by going to the URL ood.hpc.nyu.edu in your browser and selecting MATLAB from the Interactive Apps pull-down menu at the top of the page. Once you've used it and other interactive apps they'll show up on your home screen under the Recently Used Apps header.

note

Be aware that when you start from Recently Used Apps it will start with the same configuration that you used previously. If you'd like to configure your Matlab session differently, you'll need to select it from the menu.

Configuration​

You can select the version of Matlab to use, the number or cores, amount of memory, GPU type (if any), amount of time, account, and optional Slurm options.

OOD Matlab Configuration

tip

Please be aware that when you run each version of Matlab for the first time, the working directory will default to your home directory /home/NetID.

warning

Be careful not to go over your quota for /home. You can find your current usage with the myquota command. Please see our Storage documentation for details about your storage options.

Each time you start it up after that it will set its working directory to the last directory you were in. If you'd like to change this behavior, so that you always start at the same directory:

  1. click on ENVIRONMENT in your Home panel
  2. select Preferences
  3. select Current Folder
  4. select initial working folder preferences

This will allow you to set the full path of the initial working folder you would prefer. Be sure to hit the Apply button, so your changes are applied.

tip

Another step you may wish to take to keep Matlab from filling up your /home directory is to create symlinks from /scratch to /home for internal Matlab folders. You can do this by running the following commands:

# make sure you're in your /home directory
cd
mkdir /scratch/$USER/.matlab
mkdir /scratch/$USER/.MathWorks
ln -s /scratch/$USER/.matlab
ln -s /scratch/$USER/.MathWorks

Matlab running in OOD​

After you hit the Launch button you'll have to wait for the scheduler to find you node(s) to run on: OOD Matlab in queue

Then you'll have a short wait for Matlab itself to start up.
Once that happens you'll get a form that will allow you to:

  • open a terminal window on the compute node your Matlab session is running on
  • go to the directory associated with your Session ID that stores output, config and other related files for your session

Pre-launch matlab OOD

Then after you hit the Connect to Matlab button you'll have the familiar Matlab Desktop to use.
