====== Available Software ======

In the COKA Cluster are installed most of the commonly used compilers and libraries. The //Environment Modules// system is available to manage their usage, in order to select which set of compilers and/or libraries to use.

If you need some other software to be installed, you can suggest to add it, writing to: <coka-admin@fe.infn.it>

===== Environment Modules =====

Several compilers and libraries are installed, but not all of them could be used in the same environment because of conflicts (e.g. different versions of the same compiler or different implementations of the same library). The //Environment Modules//, just changing environment variables such us //$PATH// and //$LD_LIBRARY_PATH//, is able to "load" and "unload" different software components.

To load a module you can just type:

<code>module load my_module_name</code>

while to remove a module you can just type:

<code>module remove my_module_name</code>
