Intel oneAPI tools 2023.1 is available to update all tools and libraries. These further strengthen software development tools for open multivendor multiarchitecture heterogeneous/accelerated computing.
Standouts additions for 2023.1 include:
- Compiler support automatically enables bfloat16 when available which is especially powerful for AI acceleration.
- Support for just released updates to Codeplay’s oneAPI plugins for NVIDIA and AMD. The plugin updates deliver quality improvements, support Joint_matrix extension and CUDA* 11.8/testing 12, and enable gfx1032 for AMD. The AMD plugin backend now works with ROCm 5.x driver. New performance optimizations guides are available.
- Intel® VTune™ Profiler can automatically highlight profiles to gain performance utilizing high-bandwidth memory (HBM) on Intel® Xeon® Processor Max Series. For Intel® Data Center GPU Max Series, view Xe Link cross-card traffic issues such as CPU/GPU imbalances, stack-to-stack traffic, and throughput and bandwidth bottlenecks.
- Photorealistic ray tracing and path guiding from the Intel® Open Path Guiding Library (integrated in Blender and Chaos V-Ray) deliver performance increases on 4th gen Intel® Xeon® Processors.
- Updates for the latest CUDA headers and libraries to assist those migrating CUDA code to SYCL (from the SYCLomatic project).
- Intel® Arc™ GPUs have new support from Intel® Distribution for GDB on Windows.
- Intel® MPI Library enhances performance for collectives using GPU buffers and default process pinning on CPUs with E-cores and P-cores.
- Additional customer requested enhancements, and fixes.
As we have seen in the 2023 introduction, oneAPI tools and plug-ins are making real the dream of an open future for accelerated and heterogeneous computing. The approach provides paths to open source support for hardware, and it also connects to closed source library options should they be preferred (e.g., cuBLAS for NVIDIA). In other words – the goal is “no excuses” access to performance for all vendors and all architectures (not just GPUs). Codeplay Software offers prebuilt plug-ins for the oneAPI tools to add support for NVIDIA and AMD GPUs.

Innovation lives where oneAPI is Making Great Things Happen
There are many projects finding that oneAPI opens doors—by being open, multivendor, multiarchitecture, and high performance; that were otherwise closed by proprietary approaches.
Some recent developments include:
- HippoScreen uses oneAPI to help increase AI performance by 2.4x to improve efficiency and build deep learning models. How? Intel VTune Profiler recommended decreasing the thread count, as both cases involved thread oversubscription. They found the sweet spot for maximum performance and minimum CPU utilization with a thread count of 5. Great tools make a big difference. Read more in the full case study.
- AI – Hugging Face uses oneAPI to help accelerate PyTorch Transformers on 4th gen Intel Xeon processors. Read their blogs (part 1 and part 2) which talk about going from 3.5 hours, to 26 minutes, to 7.5 minutes per epoch; and other speed-ups.
- oneAPI is helping power great results as the futuristic Aurora Supercomputer is coming together. Recent results reveal exciting in these slides: Aurora performance results using Intel® Data Center GPU Max Series.
- Cambridge Open Zettascale Lab researchers lay the foundation for future computing ecosystems with help from oneAPI. Read more in the whitepaper.
- Texas Advanced Computing Center’s Frontera Supercomputer uses oneAPI to help accelerate scientific advancements.
- Purdue University launched a oneAPI Center of Excellence to expand oneAPI training.
- Univ. of Tennessee launched Rendering as a Service (RaaS) for students (they ask: “Can every student build and own a personal cloud service?”)
Available Now: Intel® oneAPI Tools 2023.1
The tools are already preinstalled and ready to use on Intel® Developer Cloud.
These programming development tools are available for download from Intel® Developer Zone, as well as via repositories and other channels.
Join oneAPI to Help Create the Best Future Together
These 
tools and plug-ins are another important step in our journey to foster an open multivendor and multiarchitecture future for computing.
The oneAPI initiative, and its open specification, are focused on enabling an open, multiarchitecture world with strong support for software developers—a world of open choice without sacrificing performance or functionality.
Please come join the growing community of those helping refine and drive this vision.
Try the tools on your own system or Intel® Developer Cloud. Get plug-ins from Codeplay. Participate in the various oneAPI groups to provide your expert advice and guidance on how to meet your needs for a productive and open solution to our software development needs. Be a part of the discussion, join oneAPI standards discussions and work, or contribute to the numerous open source projects working toward an open future for accelerated and heterogeneous computing.
