About
-----

`Snappy`_ is a compression/decompression library. It does not aim for maximum compression, or compatibility with any other compression library; instead, it aims for very high speeds and reasonable compression.

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

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

.. code-block:: bash

 module avail snappy

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

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

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

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