====== MESA OpenGL ======

   * Category: Vendor provision
   * Access method: Loaded from Linux module software
   * License: Open Source
   * Command Line: **No**
   * Desktop GUI: **Yes** (via [[:advanced:interactive|Open OnDemand]])

The MESA OpenGL module may be used on [[:advanced:interactive|Open OnDemand]] desktop sessions to provide OpenGL functionality to Linux desktop applications. This allows applications to provide 3D rendering/display functionality even if you are not running on a GPU node.

MESA generally provides sufficient performance unless your application is highly demanding. In that case you should consider running on a GPU node partition and allocating a GPU card to provide [[:advanced:software:virtualgl|hardware 3D assistance]].
===== Running =====

=== Versions ===

The software OpenGL libraries are available in one module:

<code lang=shell-session>
$ module avail Mesa

---------------------------------------- /opt/software/easybuild/modules/all ----------------------------------------
   Mesa/23.1.4-GCCcore-12.3.0    Mesa/23.1.9-GCCcore-13.2.0    Mesa/24.1.3-GCCcore-13.3.0 (L,D)
   
</code>

The generic utilities are available in another:

<code lang=shell-session>
$ module avail mesa-utils
</code>

=== Loading ===

<code lang=shell-session>
$ module load Mesa
</code>

The generic tools may be loaded separately in order to test OpenGL functionality:

<code lang=shell-session>
$ module load mesa-utils
</code>

=== Testing ===

<code lang=shell-session>
$ module load Mesa
$ module load mesa-utils
$ glxgears
...
</code>
