HP XC System 2.x Software manual Creating a Modulefile, Viewing Modulefile-Specific Help

ifort/8.0(19):ERROR:102: Tcl command execution failed: conflict ifort/8.1

In this example, the user attempted to load the ifort/8.0 modulefile, but after issuing the command to load the modulefile, an error message occurred indicating a conflict between this modulefile and the ifort/8.1 modulefile, which is already loaded.

When a modulefile conflict occurs, unload the conflicting modulefile(s) before loading the new modulefile. In the above example, you should unload the ifort/8.0 modulefile before loading the ifort/8.1 modulefile. For information about unloading a modulefile, refer to Section 2.2.7.

_________________________ Note _________________________

To avoid problems, it is recommended that you always unload one version of a modulefile before loading another version.

2.2.9 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.

A user installing a variant of a product/package already on the system should copy the existing modulefile for that product to an appropriate name, and edit it accordingly to accommodate the newly-installed product variant.

A user installing a random product/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

Users should also read the manpages for modules so that they know how to create a directory for their private modulefiles and how to use the module use <dirname> module command to use their private modules.

2.2.10 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
