FASTSUM Version 1.0: 1st public release of openQCD-FASTSUM

  • Added the possibility of using anisotropic lattice actions; see doc/anisotropy.pdf for details.

  • Added the option for smearing the gauge fields with the stout smearing technique; see doc/stout_smearing.pdf for details.

  • Merged changes by the SA2C which implemented explicit AVX-512 instructions; see README.md (AVX-512).

  • Merged the explicit BlueGeneQ optimisations developed by Dalibor Djukanovic, Mauro Papinutto, and Hubert Simma; see README.md (BlueGeneQ Optmization).

  • Collected “link like” communication routines in a single module, field_com, which reduces the memory allocation of the program.

  • The set_ud_phase and unset_ud_phase functions now also applies its changes to the cached halo, thus making it unnecessary to communicate these changes. This is only implemented for type 3 (periodic) boundary conditions as it is only needed to facilitate stout smearing.

  • Changed the flags system to also store the state of the gauge fields (phase shifted, smeared…), see modules/flags/README.flags for details.

  • Added the option to make options in the config optional, thus enabling the program to be compatible with all openQCD 1.4 and 1.6 configurations.

  • Rewrote the build system so it now builds in a separate folder and organises its contents a bit more naturally. See build/README.md.

  • Made the code base “const correct” to the extent possible without making large alterations to the code.

  • Reformatted the code base with clang-format and clang-tidy using the specifications in the attached .clang-format file as well as running clang-tidy with the options:

    -checks="readability-braces-around-statements" -fix
