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)

@jalvesz, I used LAPACK and BLAS instead of MKL for easier setup in the GitHub workflow. For future versions, we should consider using other optimized libraries such as MKL, OpenBLAS, and so on.
