oneAPI Specification

oneAPI is an open, free, and standards-based programming system that provides portability and performance across accelerators and generations of hardware. oneAPI consists of a language and libraries for creating parallel applications:

• SYCL: oneAPI’s core language for programming accelerators and multiprocessors. SYCL allows developers to reuse code across hardware targets (CPUs and accelerators such as GPUs and FPGAs) and tune for a specific architecture

• oneDPL: A companion to the DPC++ Compiler for programming oneAPI devices with APIs from C++ standard library, Parallel STL, and extensions.

• oneDNN: High performance implementations of primitives for deep learning frameworks

• oneCCL: Communication primitives for scaling deep learning frameworks across multiple devices

• Level Zero: System interface for oneAPI languages and libraries

• oneDAL: Algorithms for accelerated data science

• oneTBB: Library for adding thread-based parallelism to complex applications on multiprocessors

• oneVPL: Algorithms for accelerated video processing

• oneMKL: High performance math routines for science, engineering, and financial applications

• Ray Tracing: A set of advanced ray tracing and high-fidelity rendering and computation routines for use in a wide variety of 3D graphics uses including, film and television photorealistic visual effects and animation rendering, scientific visualization, high-performance computing computations, gaming, and more.
