Easybuild

TrinityX 15.2+ comes bundled with Easybuild. This means that TrinityX prepares the environment for Easybuild to build applications and libraries. The defaults are to use a dedicated user, typically user 'easybuild' which is being used for the actual building and compilation. Using root for building is not recommended and therefor not supported. The 'easybuild' user serves that purpose.

Search and build apps

Become the easybuild user:

# su - easybuild

Load the easybuild module:

$ module load EasyBuild

Search for specific app:

$ eb -S Pytorch
# Get output similar to this:
* $CFGS1/p/PyTorch/PyTorch-1.12.1-foss-2021a-CUDA-11.3.1.eb
* $CFGS1/p/PyTorch/PyTorch-1.12.1-foss-2021a.eb
* $CFGS1/p/PyTorch/PyTorch-1.12.1-foss-2021b-CUDA-11.5.2.eb
* $CFGS1/p/PyTorch/PyTorch-1.12.1-foss-2021b.eb
* $CFGS1/p/PyTorch/PyTorch-1.12.1-foss-2022a-CUDA-11.7.0.eb
* $CFGS1/p/PyTorch/PyTorch-1.12.1-foss-2022a.eb
* $CFGS1/p/PyTorch/PyTorch-2.6.0-foss-2024a.eb

Start compiling PyTorch-1.12.1-foss-2022a-CUDA-11.7.0.eb with a --robot flag to also install all required dependencies:

$ eb PyTorch-2.6.0-foss-2024a.eb --robot

Before installation, simulate a dry run to see all dependencies status:

$ eb PyTorch-2.6.0-foss-2024a.eb --robot --dry-run

For more flags and options, please refer to the Easybuild documentation.

Additional information

The Easybuild config templates can be found at either location:

/opt/easybuild/easybuild.d/easybuild.cfg.example
$EASYBUILD_PREFIX/easybuild.d/easybuild.cfg.example

Renaming this file to easybuild.cfg allows for further customization. After modification of the config, e.g. adding cuda capabilities, the modifications can be observed:

$ eb --show-config

Example output:

#
# Current EasyBuild configuration
# (C: command line argument, D: default value, E: environment variable, F: configuration file)
