oneAPI is an open standard, adopted by Intel, [1] for a unified application programming interface (API) intended to be used across different computing accelerator (coprocessor) architectures, including GPUs, AI accelerators and field-programmable gate arrays. It is intended to eliminate the need for developers to maintain separate code bases ...
The library supports Intel and compatible processors and is available for Linux, macOS and Windows. It is available separately or as a part of Intel oneAPI Base Toolkit. [4] Intel IPP releases use a semantic versioning schema, so that even though the major version looks like a year (YYYY), it is not technically meant to be a year. So it might ...
Intel oneAPI DPC++/C++ Compiler is available for Windows and Linux and supports compiling C, C++, SYCL, and Data Parallel C++ (DPC++) source, targeting Intel IA-32, Intel 64 (aka x86-64), Core, Xeon, and Xeon Scalable processors, as well as GPUs including Intel Processor Graphics Gen9 and above, Intel X e architecture, and Intel Programmable Acceleration Card with Intel Arria 10 GX FPGA.

Nvidia's CUDA is closed-source, whereas AMD ROCm is open source. There is open-source software built on top of the closed-source CUDA, for instance RAPIDS . CUDA is able run on consumer GPUs, whereas ROCm support is mostly offered for professional hardware such as AMD Instinct and AMD Radeon Pro .
Intel Advisor: Linux and Windows. Viewer only on macOS. C, C++, Data Parallel C++ and Fortran A collection of design and analysis tools - vectorization (SIMD) optimization, thread prototyping, automated roofline analysis, offload modeling and flow graph analysis Freeware and Proprietary. Available as part of Intel oneAPI Base Toolkit.
The DirectCompute architecture shares a range of computational interfaces with its competitors: OpenCL from Khronos Group, compute shaders in OpenGL, and CUDA from NVIDIA. The DirectCompute API brings enhanced multi-threading capabilities to leverage the emerging advanced compute resources. [2]
Intel oneAPI Math Kernel Library (Intel oneMKL) , formerly known as Intel Math Kernel Library, is a library of optimized math routines for science, engineering, and financial applications. Core math functions include BLAS , LAPACK , ScaLAPACK , sparse solvers, fast Fourier transforms , and vector math.
On Windows, it is known as Intel Visual Fortran. [2] On macOS and Linux, it is known as Intel Fortran. In 2020 the existing compiler was renamed “Intel Fortran Compiler Classic” (ifort) and a new Intel Fortran Compiler for oneAPI (ifx) supporting GPU offload was introduced.
