<p>Intel launched the oneAPI Math Kernel Library in November 1994, and called it Intel BLAS Library.<sup id="cite_ref-mklman_9-0" class="reference"><a href="#cite_note-mklman-9"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup> In 1996, the library was renamed to Intel Math Kernel Library until April 2020, when intel oneMKL has become part of oneAPI initiative to support multiple hardware architectures, holding the current name Intel oneAPI Math Kernel Library.

</p><p>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<sup id="cite_ref-license_3-1" class="reference"><a href="#cite_note-license-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> which allow redistribution.<sup id="cite_ref-licensing-faq_10-0" class="reference"><a href="#cite_note-licensing-faq-10"><span class="cite-bracket">[</span>10<span class="cite-bracket">]</span></a></sup> Commercial support for Intel oneMKL is available when purchased as part of <a href="OneAPI_(compute_acceleration)" title="OneAPI (compute acceleration)">oneAPI</a> Base Toolkit.

However, as long as the master function detects a non-Intel CPU, it almost always chooses the most basic (and slowest) function to use, regardless of what instruction sets the CPU claims to support.

</p>

<ul><li><b><a href="Linear_algebra" title="Linear algebra">Linear algebra</a>:</b> BLAS routines are vector-vector (Level 1), matrix-vector (Level 2) and matrix-matrix (Level 3) operations for real and complex single and double precision data. LAPACK consists of tuned LU, Cholesky and QR factorizations, eigenvalue and least squares solvers. MKL also includes Sparse BLAS, <a href="ScaLAPACK" title="ScaLAPACK">ScaLAPACK</a>, Sparse Solver, <a href="Eigenvalue_algorithm" title="Eigenvalue algorithm">Extended Eigensolver</a> (FEAST, PARDISO), <a href="PBLAS" title="PBLAS">PBLAS</a> and BLACS. MKL is even better at small dimensions than <a rel="nofollow" class="external text" href="https://github.com/libxsmm/libxsmm">libxsmm</a>.

<dl><dd>Since oneMKL uses standard interfaces for BLAS and LAPACK, the application which uses other implementations can get better performance on Intel and compatible processors by re-linking with MKL libraries.</dd></dl></li>

<li>oneMKL includes a variety of <b><a href="Fast_Fourier_transform" title="Fast Fourier transform">Fast Fourier Transforms</a> (FFTs)</b> from 1D to multidimensional, complex to complex, real to complex, and real to real transforms of arbitrary lengths. Applications written with the open source <a href="Fastest_Fourier_Transform_in_the_West" title="Fastest Fourier Transform in the West">FFTW</a> can be easily ported to MKL by linking with interface wrapper libraries provided as part of MKL for easy migration.

<dl><dd>Cluster versions of LAPACK and FFTs are also available as part of MKL to take advantage of MPI parallelism in addition to single node parallelism from multithreading.</dd></dl></li>

<li><b>Vector math</b> functions include computationally intensive core mathematical operations for single and double precision real and complex data types. These are similar to libm functions from compiler libraries but operate on vectors rather than scalars to provide better performance. There are various controls for setting accuracy, error mode and denormalized number handling to customize the behavior of the routines.</li>

<li><b><a href="Statistics" title="Statistics">Statistics</a></b> functions include random number generators and probability distributions, optimized for multicore processors. Also included are compute-intensive in and out-of-core routines to compute basic statistics, estimation of dependencies etc.</li>

<li><b>Data fitting</b> functions include splines (linear, quadratic, cubic, look-up, stepwise constant) for 1-dimensional interpolation that can be used in data analytics, geometric modeling and surface approximation applications.</li>

<li><b><a href="Partial_differential_equation" title="Partial differential equation">Partial Differential Equations</a></b></li>

<li><b><a href="Nonlinear_programming" title="Nonlinear programming">Nonlinear Optimization Problem Solvers</a></b></li></ul>

<p>Once, oneMKL included <a href="Deep_learning" title="Deep learning">Deep Neural Network</a> functions, but they were removed in version 2020 as a spin-off that originated the open-source Intel oneAPI Deep Neural Network Library.<sup id="cite_ref-16" class="reference"><a href="#cite_note-16"><span class="cite-bracket">[</span>16<span class="cite-bracket">]</span></a></sup>
