HP XC System 3.x Software - Manual (Page 41)

For example, if you wanted to automatically load the TotalView modulefile when you log in,
edit your shell startup script to include the following instructions. This example uses bash as
the login shell. Edit the ~/.bashrc file as follows:
# if the 'module' command is defined, $MODULESHOME
# will be set
if [ -n "$MODULESHOME" ]; then
module load totalview
fi
From now on, whenever you log in, the TotalView modulefile is automatically loaded in your
environment.
3.7 Unloading a Modulefile
In certain cases, you may find it necessary to unload a particular modulefile before you can load
another modulefile in to your environment, to avoid modulefile conflicts. See
“Modulefile
Conflicts” for information about modulefile conflicts.
You can unload a modulefile by using the module unload command, as shown in the following
example:
$ module unload ifort/8.0
Unloading a modulefile that is loaded by default makes it inactive for the current session only
— it will be reloaded the next time you log in.
3.8 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/default' -----------------
This loads the TotalView environment.
Version
Modifies: MANPATH, PATH, TVDSVRLAUNCHCMD
NOTE: The term is displayed whenever the modulefile originator does not use
version numbers to distinguish the modulefiles.
3.9 Modulefile Conflicts
Some modulefiles should not be loaded while certain other modulefiles are currently loaded.
This is especially true of modulefiles for different versions of the same software. For example,
the Intel C/C++ Version 8.0 compiler modulefile should not be loaded while the Intel
C/C++ Version 8.1
compiler modulefile is loaded. A modulefile conflict occurs in this
situation.
The system displays an error message when you attempt to load a modulefile that conflicts with
one or more currently loaded modulefiles. For example:
$ module load ifort/8.0
ifort/8.0(19):ERROR:150: Module 'ifort/8.0' conflicts with the
currently loaded module(s) 'ifort/8.1'
ifort/8.0(19):ERROR:102: Tcl command execution failed:
conflict ifort/8.1
