High Performance for Numerical Computing on CPUs and GPUs
Why oneMKL?
- 30 years at the forefront of high-performance computational math evolution.
- Take advantage of the fastest and most-used math library for Intel?-based systems.?
- Create highly performant applications faster.
- Fully use Intel hardware capabilities for AI, HPC, and data science.
- Reach high performance with math solutions like NumPy, SciPy, and MATLAB*.
What's New
Optimized for the latest generation Intel? Xeon? 6 processor.
Random Number Generation
- Even more random number distribution choices. Intel GPUs now have a new counter_engine_adaptor and support for the uint8 and uint16 types in the SYCL* Random Number Generators (RNG) Device API.
- Distribution models and data types are available for random number generators (RNG) using a SYCL device API.
- 64-bit integer types for uniform distribution
- 8-bit and 16-bit integer types for Bernoulli distribution
- Beta and gamma distributions for float and double types
Fast Fourier Transform (FFT)
- Experience faster workload execution with FFT performance improvements on Intel discrete and integrated GPUs, including the latest Intel? Arc? B-series graphics and Intel? Arc? GPU-based laptops.
- Use the combined power of multiple GPUs for 2D and 3D nonbatch FFTs with our new SYCL Discrete Fourier Transform (DFT) API.
- Reduce the footprint of your GPU applications with 12% to 40% smaller large-kernel oneMKL binaries for SYCL.

Features
Linear Algebra
Speed up linear algebra computations with low-level routines that operate on vectors and matrices and are compatible with these industry-standard BLAS and LAPACK operations:
- Level 1: Vector-vector operations
- Level 2: Matrix-vector operations
- Level 3: Matrix-matrix operations
Sparse Linear Algebra Functions
Perform various operations on sparse matrices with low-level and inspector-executor routines including the following:
- Multiply sparse matrix with dense vector
- Multiply sparse matrix with dense matrix
- Solve linear systems with triangular sparse matrices
- Solve linear systems with general sparse matrices
FFTs
Transform a signal from its original domain (typically time or space) into a representation in the frequency domain and back. Use FFT functions in one, two, or three dimensions with support for mixed radices. The supported functions include complex-to-complex and real-to-complex transforms of arbitrary length in single precision and double precision.
RNG Functions
Use common pseudorandom, quasi-random, and nondeterministic random number engines to solve continuous and discrete distributions.
Data Fitting
Provide spline-based interpolation capabilities that you can use to approximate functions, function derivatives or integrals, and perform cell search operations.
Vector Math
Balance accuracy and performance with vector-based elementary functions. Manipulate values with traditional algebraic and trigonometric functions.
Summary Statistics
Compute basic statistical estimates (such as raw or central sums and moments) for single- and double-precision multidimensional datasets.
Benchmarks
These benchmarks are offered to help you make informed decisions about which routines to use in your applications, including performance for each major function domain in oneMKL by processor family. Some benchmark charts only include absolute performance measurements for specific problem sizes. Others compare previous versions, popular alternative open source libraries, and other functions for oneMKL.
To assess performance in high-performance computing environments, see the oneMKL Benchmarks Suite. It includes:
- Intel? Distribution for LINPACK* Benchmark
- Intel? Distribution for LINPACK* Benchmark supporting MPI for clusters
- Intel? Optimized High Performance Conjugate Gradient Benchmark
