topic Hi Matt, in Intel® oneAPI Math Kernel Library

MKL, macOS, and GNU Fortran

Intel MKL Gurus,

A quick question: why is GNU Fortran not an accepted compiler for MKL on macOS?

(1264) $ $MKLROOT/tools/mkl_link_tool --os=mac -libs --compiler=gnu_f --parallel=no 

       Intel(R) Math Kernel Library (Intel(R) MKL) Link Tool v4.4
       ==========================================================

Not supported compiler for current configuration:gnu_f. Supported values for compiler: intel_c|intel_f|gnu_c|clang|pgi_f|pgi_c

Configuration
=============

OS:                     mac
Architecture:           intel64
Compiler:               gnu_f
Linking:                dynamic
Interface layer:        lp64
Parallel:               no
OpenMP library:         iomp5

I'm sure there is a good reason, but as I use GNU Fortran a lot on my Macbook (hey, free compiler) and MKL is free(-ish) at least for my experimenting/fiddling so it would be a nice option to use if I could.

Thanks,

Matt

Hi Matt,

Thank you for raising the question here. we will check and get back to you later.

It seems because historical reason - in some early version, the MKL for Mac OS is packaged as subcomponent of Intel parallel studio composer. So mainly support Intel fortran Compiler on Mac OS.

Best Regards,

Hi Matt,

There's indeed some problem with mkl_link_tool, we will investigate. Please refer to use MKL link advisor help you generating link line. Thanks.

Best regards,
Fiona

Fiona,

Sadly it looks like the online MKL Advisor doesn't have the option for gfortran+macOS either (probably because it's just running the command line tool underneath somewhere, I assume). I'm currently trying to figure out a good way to automate getting link lines in a make system. ifort is the easy one, it's PGI, GNU, etc. that take some auto-entry into the tool.

Hi Matt,

Right, both MKL link tool and advisor haven't such option. We don't support gfortran on Mac OS for a while. What i can recommend may be to use Intel fortran or PGI so far. Do you like we to create a feature request to support gfortran?

Best Regards,

Ying

Ying,

I would definitely like a feature request for supporting gfortran on macOS. I don't imagine it would be that difficult (fingers crossed).
