About
-----

`LZMA`_ support the legacy .lzma format used by LZMA Utils. We support this library to make possible the compilation of ancient code on Discoverer.

.. warning:: Users of LZMA Utils should move to :doc:`xz`. XZ Utils support the legacy .lzma format used by LZMA Utils, and can also emulate the command line tools of LZMA Utils.

Supported versions
------------------

To check which LZMA versions and build types are currently supported on Discoverer, execute on the login node:

.. code-block:: bash

 module avail lzma

The recipe followed to build the source code is available at:

https://gitlab.discoverer.bg/vkolev/recipes/-/tree/main/lzma

Loading/Compiler affinity
-------------------------

Each version of LZMA installed in the public software repository is built against four compiler sets: (i) :doc:`oneapi`, (ii) :doc:`nvidia_hpc_sdk`, (iii) :doc:`llvm` , (iv) :doc:`aocc`, (v) :doc:`gcc`. The name of the environmental module contains the name of the compiler set employed for compiling the LZMA source code.
