User customization with module
Example of environment configuration for Octave application installed on the example Example of a User application Installation page.
Login on the submit node
Login on the cluster submition node, check the page How to Access for more information:
$ ssh -l <username> hpc7.ncg.ingrid.pt
[username@hpc7 ~]$ _
Select a directory to store your modules environments
In this example we will use ~/.module on the user Home directory:
[username@hpc7 ~]$ mkdir .module
Create a modules resource file
Create a file named ~/.modulerc with the following content:
[username@hpc7 ~]$ cat .modulerc
#%Module1.0#####################################################################
##
## User prefer modules at session startup
##
module use $env(HOME)/.module
Create a configuration file for Octave application
Lets create a simple configution file for the Octave application installed on the Home directory:
[username@hpc7 ~]$ mkdir .module/octave
[username@hpc7 ~]$ cat .module/octave/5.1.0
#%Module1.0
##
## octave/5.1.0 modulefile
##
proc ModulesHelp { } {
global version
puts stderr "\tSets up Octave"
puts stderr "\n\tVersion $version\n"
}
module-whatis "Sets up Octave"
set version 5.1.0
set modroot /home/hpc/jmartins/soft/octave/$version
setenv OCTAVE_HOME $modroot
prepend-path PATH $modroot/bin
prepend-path CPATH $modroot/include
prepend-path LD_LIBRARY_PATH $modroot/lib
prepend-path PKG_CONFIG_PATH $modroot/lib/pkgconfig
Check the new modules environment
The next time you login on server you will find your environment profile available for normal usage:
[username@hpc7 ~]$ module avail
------------------- /home/hpc/jmartins/.module -------------------
octave/5.1.0
------------------- /cvmfs/sw.el7/modules/soft -------------------
aster-13.1.0 gromacs-4.6.7
blat-36.2 hdf5-1.8.16
....
Manage your new modules environment
[username@hpc7 ~]$ module load octave/5.1.0
[username@hpc7 ~]$ which octave
/home/mygroup/username/soft/octave/5.1.0
[username@hpc7 ~]$ octave
octave:1> grid # a GRID plot will popup
octave:2> exit
[username@hpc7 ~]$ module unload octave/5.1.0
[username@hpc7 ~]$ which octave
