In SQUID, the environment variable settings of the compiler, library, and application environment are managed by Environment modules. By using the module command, it is possible to set the environment variables required for using the application in a unified manner.
The main usage is shown below.


Command Description
module avail List of available development environments / apps
module list List of loaded modules
module switch [file1] [file2] Module replacement (file1 → file2)
module load [file] load a module
module unload [file] unload a module
module purge Unload all loaded modules
module show [file] Detailed display of modules


*Note: If you want to use the module command in a csh shell script, you need to execute "source /etc/profile.d/" in advance.


SQUID provides a base environment that summarizes the environment variable settings required for each calculation environment. By loading the base environment first, you can easily arrange the environment variable settings.
The base environment prepared by this system is as follows.

Type Module Name Contents
Compiler + MPI + Library BaseCPU/2021 Recommended environment for program development for general-purpose CPU nodes
BaseVEC/2021 Recommended environment for program development for Vector nodes
BaseGPU/2021 Recommended environment for program development for GPU nodes
BaseGCC/2021 Development environment when using GCC
Language environment + module BasePy/2021 Program development environment for Python
BaseR/2021 Program development environment for R
BaseJulia/2021 Program development environment for Julia
Application BaseApp/2021 Base environment for ISV and OSS application users
