EUM'25 - OpenGL support in EasyBuild

[Wed 26 Mar 2025 - 11:30-12:00 CET - in person] OpenGL support in EasyBuild Jens Henrik Göbbert (Jülich Supercomputing Centre) Heavy 3D visualization tasks can be accelerated enormously if they are supported by a GPU. The current default Easybuild configuration files only depend on Mesa for OpenGL. This limits OpenGL applications to software-accelerated rendering instead of hardware-accelerated rendering in most cases. If you want to deploy software packages that take advantage of the installed GPUs for OpenGL, a simple approach can be to install the same module twice - once for software OpenGL with Mesa and once for hardware-accelerated OpenGL using the vendor-specific OpenGL library. However, this passes the responsibility for the best choice on to the user. It would be much better if the correct OpenGL library were simply selected at runtime. To make that possible the standard approach is the use of libglvnd as a vendor-neutral dispatch layer for arbitrating OpenGL API calls between multiple vendors. It allows multiple drivers from different vendors to coexist on the same filesystem, and determines which vendor to dispatch each API call to at runtime. In this talk we want to show how libglvnd works and how it can be a key component to integrate OpenGL into the Easybuild framework in an advanced way. https://easybuild.io/eum25
