OpenGL/WebGL Support

OpenGL Support​

While OpenGL and WebGL are not officially supported on the hardware we use for the supercomputers, we have found a way to get decent, but not perfect performance by using the Mesa3D libraries. This includes open-source implementations of OpenGL, OpenGL ES, Vulkan, and OpenCL.

Steps​

  1. Request a virtual desktop on the web portal with at least 8 CPU cores
  2. In the virtual desktop, open a terminal and load the following two modules
 module load gcc-12.1.0-gcc-11.2.0
 module load mesa-22.0.2-gcc-11.2.0

  1. In the same terminal, start the application (e.g., Firefox). Applications started from this terminal will support OpenGL.

  2. (Optional) Certain websites in Firefox may still not detect OpenGL. In that case, perform these additional steps:

    a. In the address bar, type about:config (accept the risk and continue)

    b. In the list, search for webgl.force and set "webgl.force-enable" to true
