Grid'5000 provides a set of software (mainly scientific-related) using Environment modules, thanks to the module command line tool.

They are available from Grid5000 frontends or cluster's nodes (only on debianXX-big and debianXX-nfs environment if deployment is used).

The modules command

General usage

The module system is designed to load software and make it available by modifying environment (such as your PATH variable).

To get started, list available software using:

$ module avail

 Where:
  D:  Default Module

	Note
	If you need additional software to be installed, feel free to contact Grid5000 support team and we can look into it.

To load something into your environment use the load command:

$ module load gcc
$ gcc --version
gcc (Spack GCC) 11.1.0

By default, module loads the latest version available of a software (sorted by lexicographical order). You can also specify the version you need:

$ module load gcc/8.3.0_gcc-8.3.0
$ gcc --version
gcc (Spack GCC) 8.3.0

You can also find out more information about the package using whatis or show commands:

$ module whatis gcc
$ module show gcc

If you want to unload one or all the currently loaded modules, you can use:

$ module unload gcc
$ module purge

The full documentation of module command is available at: http://modules.sourceforge.net/

Using modules in jobs

The module command is not a real executable, but a shell function.

If it is not available from your shell (it might be the case if you use zsh), ensure that /etc/profile.d/lmod.sh is sourced.

In addition, module must be executed in an actual shell to work: a simple oarsub "module load gcc" will fail, you must use either:

fnancy:

oarsub 'bash -l -c "module load gcc; gcc --version"'

or alternatively:

fnancy:

oarsub ". /etc/profile; module load gcc; gcc --version"

Packages that require connection to license server

Some packages available with module are licensed and require a connection to a license server (e.g. the Intel tools). If your institution provides a license server for this software, you may forward the connection to that license server from the node where the software will be used.

For instance, to use Intel compilers from an Inria institute network (or when using Inria's VPN), you can use jetons.inria.fr license server by forwarding connections to ports 29030 and 34430 from your node using an SSH tunnel. Intel compilers must be configured to use localhost:29030 as the license server for connections to be forwarded in the tunnel. For instance, use the following commands:

# Assuming that your connecting from a network where jetons.inria.fr is available 
laptop: ssh -R 29030:jetons.inria.fr:29030 -R 34430:jetons.inria.fr:34430 <your_node>.g5k
node: module load intel-parallel-studio
node: export INTEL_LICENSE_FILE=29030@127.0.0.1
node: icc -v

Sharing modules between users

Modules can be shared between users by using a group storage.

	Note
	This documentation assume that you already know what is a group storage, and that you already have one for storing your modules. If it's not the case, check the Group Storage Documentation.

Put the modules in a dedicated folder of the group storage, so that the modules are reachable by any user belonging to the group storage.

access:

rsync modules-dir/ /srv/my-storage@storage_fqdn/modules-dir

After adding the directory to the MODULEPATH environment variable, the modules inside this directory will be loadable by other users of the group. This can be done by using one of the two following commands.

node:

module use /srv/my-storage@storage_fqdn/modules-dir

or

node:

export MODULEPATH=/srv/my-storage@storage_fqdn/modules-dir:$MODULEPATH

Finally, the modules can be loaded.

node:

module load my-personal-module
