EasyBuild is a software build and installation framework written in Python that allows you to install software in a structured, repeatable, and robust way. This talk will present the problem with building with scientific software, introduce EasyBuild, and discuss the main features of the tool.

EasyBuild is motivated by the need for a tool that allows to:

• independently install multiple versions of software side-by-side
• support multiple compilers and libraries for building software and its dependencies
• keep the software build configuration simple
• divert from the standard configure / make / make install with custom procedures (which is often necessary for scientific software)
• use environment modules for dependency resolution and making the software available to users in a transparent way
• keep record of the installation logs
• keep track of installation configuration in version control

Some key properties of EasyBuild:

• installation configuration is done using a (very concise) .eb specification file
• custom behaviour is described in easyblocks; these are Python classes that can be plugged into the EasyBuild framework
• the generation of the module files to easily make the software available to users
• the dependencies for installation are resolved using environment modules and can be automatically installed using the robot feature
• after the installation, the specification files can be sent to a repository for archiving

EasyBuild is a software build and installation framework written in Python that allows you to install software in a structured, repeatable and robust way. The tool is open-source (GPLv2), and aims to relieve to the ubiquitous problem that many HPC support team all around the world are faced with, i.e. building scientific software correctly.

EasyBuild was presented at Supercomputing'2012, where it was very well received. The paper and the slides of our talk at the PyHPC workshop at SC'12 are available through our website, see hpcugent.github.com/easybuild/.

EasyBuild is available via GitHub, spread across three repositories:

• https://github.com/hpcugent/easybuild-framework
• https://github.com/hpcugent/easybuild-easyblocks
• https://github.com/hpcugent/easybuild-easyconfigs
