Modules package provides easy and dynamic modification of shell variables adjusting it for the specific requirements of a given software package. For each ot the software packages available on the cluster there is corresponding module defined (or modules if more than one version of the package is available). Name of a module is built according to scheme <tt>program-name/version</tt>. For libraries the scheme is <tt>libs/library-name/version</tt>, and for tools (eg. programming languages such as R or Python) <tt>tools/library-name/version</tt>. For both software packages and libraries, the newest version is default, so the last part <tt>version</tt> can be omitted. Changes are made using <tt>module</tt> command and a parameter defining the action.

===Using your own modules (Advanced) ===
Modules package allows creating your own modules also. To do that you need to load first the module <tt>use.own</tt>. It will create library <tt>privatemodules</tt> in your home directory. In this directory all own modules should be placed. The <tt>modules</tt> program will automatically check new installed modules and add them to the available list. New modules can use TCL language functions. You can get more information about creating modules on the project site.
+
Modules package allows also creating your own modules in ([https://en.wikipedia.org/wiki/Tcl TCL] or https://en.wikipedia.org/wiki/Lua_(programming_language) Lua]). Your own modules should be stored in directory, which could be added to module listing with <tt>module use /path/to/personal/modulefiles</tt> command. You can get more information about creating modules on the project site.

Package description

Lmod package provides easy and dynamic modification of shell variables adjusting it for the specific requirements of a given software package. For each ot the software packages available on the cluster there is corresponding module defined (or modules if more than one version of the package is available). Name of a module is built according to scheme program-name/version. For libraries the scheme is libs/library-name/version, and for tools (eg. programming languages such as R or Python) tools/library-name/version. For both software packages and libraries, the newest version is default, so the last part version can be omitted. Changes are made using module command and a parameter defining the action.

  • module add <module> or module load <module> – load the program module
  • module rm <module> or module unload <module> – remove the program module


  • module list – show list of currently loaded modules
  • module avail – show list of all available modules
  • module avail <software_name> – show all versions of given software_name


  • module purge – remove all loaded modules
  • module show <module> or module display <module> – show information about given module
  • module swap <module-1> <module-2> – exchange modules in shell


  • module save [collection-name] - save loaded modules into default collection or collection named collection-name
  • module restore [collection-name] - loadmodules from default collection or named collection
  • module savelist - list saved collections

Using your own modules (Advanced)

Modules package allows also creating your own modules in (TCL or https://en.wikipedia.org/wiki/Lua_(programming_language) Lua]). Your own modules should be stored in directory, which could be added to module listing with module use /path/to/personal/modulefiles command. You can get more information about creating modules on the project site.

-- -*- lua -*-
local pkgName     = myModuleName()
local fullVersion = myModuleVersion()

whatis("Name: "..pkgName)
whatis("Version "..fullVersion)
whatis("Category: apps/chemistry")
whatis("Description: Molcas@UU 8.0 (v.15-06-18) quantum chemistry chemistry package")
whatis("URL: http://www.kvant.kemi.uu.se/molcas/index.html")
whatis("Keyword: QC, chemistry")

-- add path to Molcas to PATH environmental variable and set MOLCAS environmental variable 
prepend_path('PATH','/net/archive/groups/plg******/software/molcas.uu.8/molcas-8.0-15.06.18_CentOS_7.0_x86_64/bin')

if (os.getenv('SLURM_JOB_ID') ~= nil) then
  setenv('MOLCAS_WORKDIR', os.getenv('SCRATCHDIR'))
