oneAPI Specification#

oneAPI is an open, free, and standards-based programming system thatprovides portability and performance across accelerators andgenerations of hardware. oneAPI consists of a language and librariesfor creating parallel applications:

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

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

• oneDNN: High performance implementations ofprimitives for deep learning frameworks

• oneCCL: Communication primitives for scaling deeplearning 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 parallelismto complex applications on multiprocessors

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