The paper, like many involving comparisons/benchmarks,
is IMHO flawed. The author does not give the options
used with the various compilers.  The author also used
a 3 year old version of gfortran from 2021 and compares
it to 2023 versions of flang.  I cannot find the release
date for Cray Fortran 15.0.0.

PS: The Fortran compiler available from LLVM github is
named flang-new.  There is no compiler named flang.
