Notes

  • Changes from 2021.2 and related notes
    • Intel MPI version was changed to 2018; 2020 version got stuck on a test (there may be other ones).
    • Double precision version with MKL still failed on tests (this does not happen for intel compiler version). We thus don't use MKL for double precision version.
  • Double precision version failed on GammaDistributionTest test. (numerical error)
