Configuration steps
Configure new-style modules in .bashrc
To switch over to new hierarchical module names on both CentOS releases you could continue making all your module choices in ~/.bashrc
and simply signal on the older platform to use the new module style. You would do this by creating an empty new-style customization file: touch ~/.modules-el6
.
Configure modules in dedicated files
However, it is cleaner to move the module selection into dedicated files:
- Move your previous module selections inro a conspicuously named but otherwise unused file, e.g.,
.modules-el5.inactive
. - Duplicate the file and adapt its contents to new module 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
.
- Remove version numbers from module names of the old-style
- Remove all previous module customizations from
~/.bashrc
. - Test.
cd # Go to home directory
grep -A 1 module .bashrc > .modules-el5.inactive
cp .modules-el5.inactive .modules-el6
vi .modules-el6 # adapt module names, clean up errant lines
vi .bashrc # remove all lines with "module" commands
# Test
exec bash -l
module list
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
