          >[edited:] Please check the latest results for the dot product generated by the GitHub Action workflow.: https://github.com/gha3mi/forbenchmark/tree/main/benchmarks/dot

Excellent! These results are very interesting! I'll push a version as is, though locally I had to:

• remove link = ["lapack", "blas"] from the fpm.toml (when running with ifort and ifx)
• switch -llapack -lblas for -qmkl for both ifort and ifx in the fpm.rsp
• Oh, and for inlining with ifx: -flto=full instead of -ipo
  (haven't test nvfortra as I have to clean up my install)

dot_product

          This might be more representative:

a = 0._rk
do nl = 1,bench%nloops
      a = a + dot_product(u,v)
end do
call bench%stop_benchmark(cmp_gflops)
print *, a

The cumulative variable + the print forces the compiler to avoid optimizing to actually print the correct value. Removed m2 as it was stagnating:
ifort

ifx

gfortran
