Migration to new-style module names
Rules
Adapt existing module load commands to new-style names as follows:
- Remove version numbers from module names of the old-style
packagename/version
, leaving onlypackagename
. This is the recommended approach, as you will automatically benefit from future updates. - To insist on a specific version for a package affected by the new-style names, use the form
packagename/compilername/version
orpackagename/mpiname/compilername/version
as appropriate. To see available flavors and versions, separately run the commandmodule avail packagename
.
Configure in .bashrc
To switch over to new hierarchical module names on both CentOS releases you could continue making all your module choices in ~/.bashrc
.
vi .bashrc
- Apply the changes shown in the #Rules section.
- Tell CentOS-5 nodes to use the new module style as well. Simply create an empty customization file:
touch ~/.modules-el6
Configure in dedicated files
It is perhaps cleaner to perform the module selection in dedicated files. To migrate your existing configuration:
- Move your previous module selections into a conspicuously named but otherwise unused file, e.g.,
.modules-el5.inactive
.
cd # Go to home directory
grep -A 1 module .bashrc > .modules-el5.inactive
- Duplicate the file.
cp .modules-el5.inactive .modules-el6
- Adapt contents to new module names, just as shown for
.bashrc
in the previous section. Clean up errant lines that the grep above might have included.
vi .modules-el6
- Apply the changes shown in the #Rules section.
- Edit
~/.bashrc
and remove all lines with "module" commands.
vi .bashrc
- Test.
bash -l # open a sub-shell (option is lowercase L)
module list
exit # leave the sub-shell
CentOS-dependent module selection
If you encounter difficulties with making your module selection work simultaneously for CentOS-5 and CentOS-6, use separate configurations instead.
- Follow the steps as above.
- Re-activate the older module selection.
- Test.
cd # Go to home directory
mv .modules-el5.inactive .modules-el5
vi .modules-el5 # clean up errant lines
# Test
exec bash -l
module list
