Intel® oneAPI

A Unified X-Architecture Programming Model


oneAPI is a cross-industry, open, standards-based unified programming model that delivers a common developer experience across accelerator architectures-for faster application performance, more productivity, and greater innovation. The oneAPI industry initiative encourages collaboration on the oneAPI specification and compatible oneAPI implementations across the ecosystem.


Programming Challenges For Multiple Architectures

In today’s HPC landscape, several hardware architectures are available for running workloads – CPUs, GPUs, FPGAs, and specialized accelerators. No single architecture is best for every workload, so using a mix of architectures leads to the best performance across the most scenarios. However, this architecture diversity leads to some challenges:

Each architecture requires separate programming models and toolchains:
  • Required training and licensing – compiler, IDE, debugger, analytics/monitoring tool, deployment tool – per architecture
  • Challenging to debug, monitor, and maintain cross-architectural source code
  • Difficult integration across proprietary IPs and architectures and no code re-use
Software development complexity limits freedom of architectural choice.
  • Isolated investments required for technical expertise to overcome the barrier-to-entry

How oneAPI Can Help

  • OneAPI delivers a unified programming model that simplifies development across diverse architectures. With the oneAPI programming model, developers can target different hardware platforms with the same language and libraries and can develop and optimize code on different platforms using the same set of debug and performance analysis tools.
  • Using the same language across platforms and hardware architectures makes source code easier to re-use; even if platform specific optimization is still required when code is moved to a different hardware architecture, no code translation is required anymore. And using a common language and set of tools results in faster training for new developers, faster debug and higher productivity.
