The Intel® Math Kernel Library (Intel® MKL) provides developers of scientific, engineering and financial software with a set of linear algebra routines, fast Fourier transforms, and vectorized math and random number generation functions, all optimized for the latest Intel® Pentium® 4 processors, Intel® Xeon® processors with Streaming SIMD Extensions 3 (SSE3) and Intel® Extended Memory 64 Technology (Intel® EM64T), and Intel® Itanium® 2 processors. This software also performs well on non-Intel (x86) processors.
Intel® MKL provides linear algebra functionality with LAPACK (solvers and eigensolvers) plus level 1, 2, and 3 BLAS offering the vector, vector-matrix, and matrix-matrix operations needed for complex mathematical software computations. Users who prefer the FORTRAN 90/95 programming language may call LAPACK driver and computational subroutines via special interfaces with reduced numbers of arguments. Intel® MKL provides ScaLAPACK (Scalable LAPACK) and support functionality including the Parallel Basic Linear Algebra Subprograms (PBLAS). For solving sparse systems of equations, Intel® MKL provides direct and iterative sparse solvers as well as a supporting set of sparse BLAS (levels 1, 2, and 3).
Intel® MKL offers multidimensional fast Fourier transforms (1D, 2D, 3D) with mixed radix support (not limited to sizes of powers of 2). Intel® MKL also provides distributed versions of these functions for use on clusters. For the solution of partial differential equations (PDE), Intel® MKL provides a few preconditioners to help with the convergence of our iterative solvers. Optimization [Trust Region] solvers provide efficient routines for solving nonlinear least square problems with and without boundary constraints.
Intel® MKL also includes a set of vectorized transcendental functions (called the Vector Math Library (VML)) offering both greater performance and excellent accuracy compared to the libm (scalar) functions. The Vector Statistical Library (VSL) offers high performance vectorized random number generators for a number of probability distributions as well as convolution and correlation routines.
The BLAS, LAPACK, direct sparse solver (DSS/PARDISO), FFT, VML library functions, and optimization solvers in Intel® MKL are threaded using OpenMP*. All of Intel® MKL is thread-safe (with the exception of the deprecated ?lacon, ?lasq3, and ?lasq4 LAPACK routines; see the reference manual for more information).
New in Intel® MKL 10.1
