[5][6][7] Intel oneAPI Math Kernel Library is not to be confused with oneMKL Interfaces, an open-source wrapper library that allows DPC++ applications to call oneMKL routines that can be offloaded to multiple hardware architectures and vendors defined during runtime.

The library is available as part of oneAPI Toolkits and in a standalone form, free of charge under the terms of Intel Simplified Software License[3] which allow redistribution.

Following Apple’s transition away from x86 CPUs, Intel oneMKL last release available for macOS is the version 2023.2.2 and it is scheduled for removal by the end of 2024.

[11] As of 2020[update], Intel's MKL remains the numeric library installed by default along with many pre-compiled mathematical applications on Windows (such as NumPy, SymPy).

[14] Intel oneMKL has the following functional categories:[15] Once, oneMKL included Deep Neural Network functions, but they were removed in version 2020 as a spin-off that originated the open-source Intel oneAPI Deep Neural Network Library.
