HP XC System 3.x Software - Manual (Page 35)

When a modulefile conflict occurs, unload the conflicting modulefile before loading the new modulefile. In
the previous example, you should unload the ifort/8.0 modulefile before loading the ifort/8.1
modulefile. For information about unloading a modulefile, see
Unloading a Modulefile (page 34) .
Note
To avoid problems, HP recommends that you always unload one version of a modulefile before loading
another version.
Creating a Modulefile
If you download or install a software package into a private directory, you can create your own (private)
modulefile for products that you install by using the following general steps:
1. Create a private modulefiles directory.
2. Copy an existing modulefile (to use as a template), or copy the software's corresponding default
modulefile from under /opt/modules/modulefiles, into the private modulefiles directory.
3. Edit and modify the modulefile accordingly.
4. Register the private directory with the module use command.
To install a variant of a product or package already on the system, copy the existing modulefile for that
product to an appropriate name, and edit it accordingly to accommodate the newly-installed product variant.
To install a random product or package should look at the manpages for modulefiles, examine the existing
modulefiles, and create a new modulefile for the product being installed using existing modulefiles as a
template. To view modules manpages, load the modules modulefile and then display the modulefile
manpage:
$ module load modules
$ man modulefile
Read the manpages for modules so that you know how to create a directory for your private modulefiles
and how to use the module use <dirname> module command to use your private modules.
Viewing Modulefile-Specific Help
You can view help information for any of the modulefiles on the HP XC system. For example, to access
modulefile-specific help information for TotalView, issue the module help command as follows:
$ module help totalview
----------- Module Specific Help for 'totalview' -----------------
This loads the TotalView environment.
