That linked article from 2016 is about Intel's Custom Foundry program, which I'm fairly sure is for building chips under contract to other companies. It promotes that they have "access to ARM Artisan IP," but doesn't specifically mention an ARM version of MKL that I see. The list of compatible hardware Intel's page on MKL itself lists compatible processors and ARM is conspicuously absent: https://software.intel.com/content/www/us/en/develop/tools/math-kernel-library.html https://software.intel.com/content/www/us/en/develop/tools/m... And, this question on Intel's own forums from 2016 at least suggests that there wasn't an MKL version for ARM in the time frame of the article you're linking to, either: https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/MKL-gfortran-on-ARM-processors-e-g-Raspberry-Pi-3-quad-core/td-p/1086157 https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Libr... So, from what I can tell, while Intel is an ARM licensee and made ARM CPUs in the past, they haven't made their own ARM CPUs for years and there's no sign they ever made MKL for any ARM platform. Never say never, but I think the OP is basically right -- there's not a lot of incentive for Intel to produce one.
