The Intel® Math Kernel Library includes Fortran routines and functions optimized for Intel® processor-based computers running operating systems that support multiprocessing. In addition to the Fortran interface, Intel MKL includes a C-language interface for the Discrete Fourier transform functions, as well as for the Vector Mathematical Library and Vector Statistical Library functions. For hardware and software requirements to use Intel MKL, see Intel® MKL Release Notes.
The Intel® Math Kernel Library includes the following groups of routines:
Basic Linear Algebra Subprograms (BLAS):
- vector operations
- matrix-vector operations
- matrix-matrix operations
Sparse BLAS Level 1, 2, and 3 (basic operations on sparse vectors and matrices)
LAPACK routines for solving systems of linear equations
LAPACK routines for solving least squares problems, eigenvalue and singular value problems, and Sylvester's equations
Auxiliary and utility LAPACK routines
ScaLAPACK computational, driver and auxiliary routines (only in Intel MKL for Linux* and Windows* operating systems)
PBLAS routines for distributed vector, matrix-vector, and matrix-matrix operation
Direct and Iterative Sparse Solver routines
Vector Mathematical Library (VML) functions for computing core mathematical functions on vector arguments (with Fortran and C interfaces)
Vector Statistical Library (VSL) functions for generating vectors of pseudorandom numbers with different types of statistical distributions and for performing convolution and correlation computations
General Fast Fourier Transform (FFT) Functions, providing fast computation of Discrete Fourier Transform via the FFT algorithms and having Fortran and C interfaces
Cluster FFT functions (only in Intel MKL for Linux* and Windows* operating systems)
Tools for solving partial differential equations - trigonometric transform routines and Poisson solver
Optimization Solver routines for solving nonlinear least squares problems through the Trust-Region (TR) algorithms and computing Jacobi matrix by central differences
Basic Linear Algebra Communication Subprograms (BLACS) that are used to support a linear algebra oriented message passing interface
Data Fitting functions for spline-based approximation of functions, derivatives and integrals of functions, and search
GMP arithmetic functions

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.
