Development toolchains

Much of the software available on Stanage was installed using EasyBuild, which is a tool for building and installing software on HPC systems.

EasyBuild groups core sets of dependencies as what it calls toolchains. The two supported toolchains on Stanage are:

• foss

  • C, C++ and Fortran compilers: GCC

  • MPI implementation: OpenMPI

  • BLAS and LAPACK implementation: OpenBLAS

  • Parallel, distributed LAPACK implementation: ScaLAPACK

  • Fourier transforms: FFTW

• intel

  • C, C++ and Fortran compilers (icc/icpc/ifort)

  • MPI implementation (Intel MPI)

  • BLAS, LAPACK and fourier transforms: Intel MKL

Dependency versions for toolchains

See the EasyBuild documentation for dependency versions for foss and intel

Sub-toolchains

In addition to the above toolchains there are sub-toolchains corresponding to subsets of the main toolchain dependencies:

• gompi: GCC + openmpi

• gompic: GCC + OpenMPI + CUDA

• gcccuda: GCC + CUDA

• iccifort: icc + ifort

• iimpi: icc + ifort + impi
