Attention

The Bessemer HPC service was decommissioned on 2025-10-31 and can no longer be accessed by users. Removal of Bessemer references in our documentation is ongoing

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

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
