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 [
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.
3.8Viewing Modulefile-Specific Help
You can view help information for any of the modulefiles on the HP XC system. For example, to access
$ module help totalview
This loads the TotalView environment.
Version <default>
Modifies: MANPATH, PATH, TVDSVRLAUNCHCMD
NOTE: The term <default> 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
