# oneAPI Math Kernel Library - Data Parallel C++ Developer Reference¶

The oneAPI Math Kernel Library (oneMKL) improves performance with math routines for software applications that solve large computational problems. oneMKL provides BLAS and LAPACK linear algebra routines, fast Fourier transforms, vectorized math functions, random number generation functions, and other functionality.

This publication describes the Data Parallel C++ (DPC++) interface. DPC++ = ISO C++ and Khronos SYCL and extensions.

Basic Linear Algebra Subprograms (BLAS) - The BLAS routines provide vector, matrix-vector, and matrix-matrix operations.

Sparse BLAS - The Sparse BLAS routines provide basic operations on sparse vectors and matrices.

LAPACK - The LAPACK routines solve systems of linear equations, least square problems, eigenvalue and singular value problems, and Sylvester’s equations.

Random Number Generators - The Random Number Generators provides a set of routines implementing commonly used pseudorandom and quasi-random generators with continuous and discrete distributions.

Summary Statistics - Summary Statistics provides routines that compute basic statistical estimates for single and double precision multi-dimensional datasets.

Vector Mathematics Functions - The Vector Mathematics (VM) functions compute core mathematical functions on vector arguments.

Fourier Transform Functions - The Fourier Transform Functions offer several options for computing Fast Fourier Transforms (FFTs).

Optimization Notice |
---|

Intel’s compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice. Notice revision #20110804 |
