OpenOnDemand

OpenOnDemand is a platform for running computational tasks on a cluster from a web browser. If those tasks are interactive, it provides the ability to interact with them once the task has started its execution. OpenOnDemand has an "App" based plugin system for adding new types of computational tasks and interactivity.

One of the greatest benefits of this system is remote access to large machines for computational tasks, without the need for utilizing a commnand-line interface that is difficult to learn.

Our installation is available at https://ondemand.beocat.ksu.edu

File Management

File management can be accessed through the Files dropdown in the dashboard.

Files Dropdown

Once you click on Home Directory, you can manage your files, upload/download/rename/edit and view.

RStudio

RStudio is one of the interactive applications that we've enabled for use within OpenOnDemand

You launch interactive apps through the "Interactive Apps" dropdown.

Once you click on RStudio, you'll be brought to a page allowing you to specify requirements for your RStudio run, e.g. memory, cores, and runtime.

Once the job is submitted, the scheduler will take it and run it when space is available. Once the job is running, "My Interactive sessions" page will look like this:

From there, you can connect to RStudio and it will bring you to a familiar interface.

Shell Access

Somethings, no matter how hard we try, are easier to do via the command line. OpenOnDemand also gives you a way to handle those cases via the Clusters dropdown

You can choose an individual headnode, if need-be, or you can choose "Beocat Shell Access" to be given one of the headnodes at random. Once chosen, you should be able to have a familiar command-line experience
