supported modules in config_machines.xml

[pansah]

Hi,
Is there any documentation on supported modules for the lines below in the the config_machines.xml script? What if I set modules to "none"... What happens?
Thank you!

Software module systems
<!-- allowed types are none, module, soft -->
<module_system type="module">
<modules>
<command name="purge"/>
<command name="load">ncarenv/1.0</command>
</modules>
<modules compiler="intel">
<command name="load">intel/16.0.3</command>
<command name="load">mkl</command>
</modules>
</module system>
<modules mpilib="mpt">
<command name="load">netcdf/4.4.1</command>
<!-- <command name="load">netcdf-mpi/4.4.1</command> -->
<command name="load">pnetcdf/1.8.0</command>
</modules>
</module_system>

Also, do I really have to load netcdf and pnetcdf??

If you set modules to none you don't use modules and the build will only use compilers and libraries it finds in your path.
You do need netcdf. pnetcdf is optional but recommended if you have a parallel file system.

Thanks! That was helpful.

Thanks! That was helpful.

However, why do we need to specify the modules when it can find all the necessary tools it needs in our path.

If you have everything you need in your path you can set modules="none" and not use them.
Modules allow the use of multiple environments (compilers, mpi librairies, etc) which cannot all be in the environment at the same time.

Great. Thanks!
