The objective of this repository is to pilot in an easy way the building process of software used within the UL HPC platform.
Wished features:
- Automatic Management of Environment Modules deployment
- Fully automates software builds and supports all available toolchains
- Clean (hierarchical) modules layout to facilitate its usage
- Easy to use
- Minimal requirements (Python 2.x, Ruby >= 1.9.3, Environment modules (Tcl/C or Lmod)
- Management of software / module sets for which different policies applies, for instance:
-
core: set of software present by default, who deserve a special attention (automatic software testing reported on Cdash, etc.) -
ulhpc: in addition to core, all built software available to the users
-
- Coherent workflow for both the UL HPC sysadmins and users to cover the following scenarios:
- [admin] Deployment from scratch of a new software stack
- [user] Build a new software on top of the existing stable stack
- [power user] as above, and contribute back to the deployed infrastructure (pull request etc.)
- [admin] add a new software to a software set, on top of the existing stable stack
- [admin] test the successful building of a given software set (in
/tmp/or/dev/shm) - [admin] prepare a new major / minor / patch release
- Reproducible and self-contained deployment, coupled with a strongly versioned release mechanism to facilitate access to old environments
For this purpose, the proposed workflow relies heavily on Easybuild, a flexible framework for building/installing (scientific) software.
