Most software packages are built from a compiler toolchain. A toolchain consists of one or more compilers, together with some libraries for using an MPI stack and commonly used math libraries. Well-known packages include BLAS/LAPACK APIs for linear algebra routines.
EasyBuild supports several different toolchains. The Hutch uses the foss toolchain, which is an acronym for Free Open Source Software. Foss is based on the GNU compiler tools. Toolchains are curated twice a year and named for the year, and labeled a or b, i.e., foss-2019b. When loading multiple modules for a workflow, always load modules from the same toolchain. Do not mix and match modules from different toolchains.
