Attention

WARNING: From 9am on 19th August until 5pm on 2nd September there will be no access to the Stanage HPC cluster.

We will send an email to notify you when Stanage is back online and available for job submission.

Development toolchains

Much of the software available on Bessemer 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 three supported toolchains on Bessemer are:

• foss

  • C, C++ and Fortran compilers: GCC

  • MPI implementation: OpenMPI

  • BLAS and LAPACK implementation: OpenBLAS

  • Parallel, distributed LAPACK implementation: ScaLAPACK

  • Fourier transforms: FFTW

• fosscuda

  • As per foss

  • Plus CUDA

• 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

fosscuda-2019a has the same dependencies as foss-2019a plus CUDA 10.1. fosscuda-2019b has the same dependencies as foss-2019b plus CUDA 10.1 update 1.

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
