Intel® oneAPI Toolkits

Deliver uncompromised performance for diverse workloads across multiple architectures

Intel® oneAPI

oneAPI is the productive, smart path for accelerated computing, freeing developers from the economic and technical burdens of proprietary programming models. It’s an open alternative to proprietary language lock-in that enables the full performance of the hardware with a complete, proven set of tools that complement existing languages and parallel models.


oneAPI and Intel® oneAPI Toolkits together bring productive and performant cross-architecture programming to developers.

Future-ready programming model provides freedom of choice

  • An open alternative to single-vendor/proprietary lock-in enables easy architecture retargeting.
  • Apply your skills to the next innovation, not rewriting software for the next hardware platform.

Realize all the hardware value

  • Expose and exploit all the cutting-edge features and maximize performance of the latest hardware architectures–CPUs, GPUs, FPGAs, and other accelerators alone or in any combination. – e.g. 3rd gen Intel® Xeon® Scalable processors enable Intel® Advanced Vector Extensions 512 (Intel® AVX-512), including Intel® Deep Learning Boost and bfloat16 acceleration for optimal AI performance.
  • Performance for Accelerated Architectures – Take full advantage of accelerated compute by maximising performance across Intel CPUs, GPUs and FPGAs.

Confidently develop performant code quickly and correctly

  • Fast efficient development with a complete set of cross-architecture libraries and advanced tools.
  • Shorter learning curve with familiar languages and standards; is interoperable with existing HPC programming standards including Fortran, C/C++, OpenMP and MPI, as well as Python with a rich set of optimised Python libraries.
  • Easy integration with legacy code including migration of CUDA code to DPC++.
