Sol can be accessed through the Open OnDemand web portal. Open OnDemand (OOD) is an NSF-funded open-source HPC portal developed by the Ohio Supercomputing Center. The goal of OOD is to provide an easy way for system administrators to provide web access to their HPC resources, including, but not limited to:
...
Traditionally, HPC resources can only be accessed via a ssh client either in built for Linux & Mac OSX or third party tools such as Putty, MobaXterm, etc on Windows. By providing a web interface to access HPC resources, OOD provides the ability to login from devices such as smartphones, tablets, etc that do not have an easy to use SSH client.
Connecting to the HPC Portal
To connect to the portal, use the url visit https://hpcportal.cc.lehigh.edu using your favorite browser, VPN required to access from off campus location.
...
...
Due to a bug when using websockets, the Cluster and Interactive Apps of Open OnDemand do not work with Safari. If Safari is your favorite browser, you should find a new favorite browser when using the HPC Portal.

The dashboard has several dropdown menus that you need to get familiar with for using OOD. You will not see the "Develop" dropdown. This is an admin feature for developing applications that eventually will be added to OOD.

Application
The following applications are available on the portal
- Virtual Desktops
- Jupyter Notebooks
- RStudio Server
- Abaqus CAE
- Ansys Workbench
- Maple
- MATLAB
- Mathematica
Any application that has a GUI can in principle be accessed in the Virtual Desktop application. However, it should be noted that a full desktop environment is not installed on the compute nodes. Instead, MATE and XFCE desktop environments are bundled in a singularity container. There may be some peculiarities with the software you are interested in using that this setup may not provide you with a good user experience. Please see Virtual Desktops for more information.Advanced users may choose to use the shell to access the cluster and continue using the cluster.
