  • New features and bug fixes. See the Release Notes for more information.

New in Intel® oneAPI Base Toolkit 2024.0

Toolkit Level Updates

  • Directory layout is improved across all products to streamline installation and setup. The Unified Directory Layout is implemented in 2024.0. If you have multiple toolkit versions installed, the Unified layout ensures that your development environment contains the correct component versions for each installed version of the toolkit.  The directory layout used before 2024.0, the Component Directory Layout, is still supported on new and existing installations.
    For detailed information about the Unified layout, including how to initialize the environment and advantages with the Unified layout, refer to Use the setvars and oneapi-vars Scripts with Linux and Use the setvars and oneapi-vars Scripts with Windows.
  • Intel® developer tools now maximize performance on upcoming Intel 5th Generation Xeon Scalable Processors (formerly known as Emerald Rapids) and the Intel® Core™ Ultra processors (formerly known as Meteor Lake)
  • Improved installation directory layout provides faster environment setup. 
  • Intel® oneAPI DPC++/C++ Compiler fully implements the SYCL 2020 specification, improving developer productivity and boosts CPU and GPU offload performance, and enhances OpenMP 5.0, 5.1, 5.2 standards compliance
  • Intel® oneAPI DPC++/C++ Compiler adds popular LLVM sanitizers to easily catch C++, SYCL, OpenMP address, memory leak, uninitialized memory, thread data races, deadlocks and undefined behavior on CPU.
  • Several advanced preview features are available for evaluation including C++ parallel STL for easy GPU offload, dynamic device selection to optimize compute node resource usage, SYCL graph for reduced GPU offload overhead, and thread composability to prevent thread oversubscription between oneTBB and OpenMP.
  • Starting with this release, the Intel Level Zero and OpenCL™ GPU driver exposes  each GPU tile of the Intel® Data Center GPU Max Series differently, which also affects the way these devices are exposed in SYCL and OpenMP. Prior to this change, each card was exposed as a root device and tiles were exposed as sub-devices. Now, each tile is exposed as a root device by default. This also affects how root devices can be partitioned into sub-devices. The old behavior can be enabled via the ZE_FLAT_DEVICE_HIERARCHY environment variable. As a result, use of the environment variables ONEAPI_DEVICE_SELECTOR and ZE_AFFINITY_MASK may need to change because the number of root devices and the availability of sub-devices is different than in prior releases. Refer to the GPU optimization guide and the article Options for using a GPU Tile Hierarchy for more details.

Intel® oneAPI DPC++ Compiler 2024.0.1

  • SYCL Bindless textures are fixed and now work correctly on NVidia® hardware via the Codeplay® NVidia® plugin.
  • The OpenMP* runtime library is updated to support Intel® Core™ Ultra devices.

Intel® oneAPI DPC++ Compiler 2024.0.0

  • Intel® oneAPI DPC++/C++ Compiler implements the SYCL 2020 specification, improving developer productivity and boosts CPU and GPU offload performance, and enhances OpenMP 5.0, 5.1, 5.2 standards compliance
  • The compiler adds popular LLVM sanitizers to easily catch C++, SYCL, OpenMP address, memory leak, uninitialized memory, thread data races, deadlocks and undefined behavior on CPU.
  • The compiler significantly improves developer productivity by adding an easier way to adapt C++ code using virtual functions to run with SYCL device offload, improved error messaging and error handling for SYCL and OpenMP code.

Intel® oneAPI DPC++ Library 2022.3.0.0

  • Dynamic device selection technology preview to choose between round robin, load based and auto tune policy to schedule work on available compute devices
  • Improved performance of merge, sort, stable_sort, and sort_by_key, reduce, min_element, max_element, minmax_element, is_partitioned, and lexicographical_compare algorithms with DPC++ execution policies.

Intel® DPC++ Compatibility Tool 2024.0.0

  • Improved migration coverage for cuBlase, cuSolver, cuDNN, NCCL,  CUB, Thrust, CUDA Math APIs.
  • Enhanced performance portability of auto migrated SYCL code demonstrated by Velocity Bench Application Suite on Intel® Data Center Max Series GPU.

Intel® oneAPI Math Kernel Library 2024.0.0

  • Integrates Vector Math optimizations into Random Number Generators for high performance computer simulations, statistical sampling, and other areas on x86 CPUs and Intel GPUs.

Intel® Distribution for GDB* 2024.0.0

  • Intel Distribution for GDB* enhances the developer experience, both in the command line and when using Microsoft* Visual Studio and Visual Studio Code* by boosting the debugger performance, refining the user interface, and streamlining the debugging process. These improvements allow developers to efficiently debug code for CPUs and GPUs, improving their overall experience.

  • Intel Distribution for GDB* provides an improved scheduler locking mechanism with greater control, allowing users to fine-tune the scheduler lock. This enables developers to tailor the lock's behavior according to their preferences and specific debugging needs.

  • Intel® VTune™ Profiler implements support for pinpointing performance bottlenecks for the applications running on Intel® Core™ Ultra and 5th Gen Intel® Xeon® processors.
  • Intel® VTune™ profiles the code offloaded to NPU (Neural Processor Units) on Intel® Core Ultra procdssors. It helps understand how much data is transferred from NPU to DDR memory and identify the most time-consuming tasks running on NPU. This feature is currently in technical preview.  
  • ntel® VTune™ Profiler provides understanding of cross GPU traffic and bandwidth through Xe Link for each node using Application Performance Snapshot.

Intel® Advisor 2024.0.0

  • Intel® Advisor adds support for the 4th Gen Intel® Xeon® Scalable Processors with support for FP16 and BF16 extensions and AMX profiling.

How to Start Using the Tools

Please reference:

Known Issues, Limitations and Workarounds

  1. Known Issue: The modulefiles included with Intel® VTune™ Profiler and Intel® Advisor incorrectly derive the component root path as "/". Workarounds for this issue include:
    • For Intel VTune Profiler:
      1. Click here to download the fixed tcl file and replace the existing 2024.0 file located in <install-dir>/vtune/2024.0/etc/modulefiles/vtune/
      2. Instead of using "module load" to set up the environment variables, run:

        $ source <install-dir>/vtune/latest/vtune-vars.sh

    • For Intel Advisor:

      1. Click here to download the fixed tcl file and replace the existing 2024.0 file located in <install-dir>/advisor/2024.0/etc/modulefiles/advisor/

      2. Instead of using "module load" to set up the environment variables, run:

        $ source <install-dir>/advisor/latest/advisor-vars.sh

  2. Known Issue: There is a known issue integrating Intel software developer tools (Intel® oneAPI Base Toolkit, Intel® HPC Toolkit, or their component products) into Microsoft Visual Studio* 2022 (17.7 or higher) on offline systems with the Windows Performance Toolkit (Win11SDK_WindowsPerformanceToolkit) installed. This results in an incomplete integration. To work around the issue, either enable an Internet connection during Intel developer tools installation or uninstall the Windows Performance Toolkit before installing Intel developer tools, after Intel developer tools are installed, reinstall the Windows Performance Toolkit.
  3. Known Issue: When using Intel® oneAPI DPC++/C++ Compiler on a Linux machine, users may run into an issue if the highest version of GNU gcc detected doesn't have the equivalent g++ package installed. More details on the error and workarounds can be found here.
  4. Please read the whitepaper on Challenges, tips, and known issues when debugging heterogeneous programs using DPC++ or OpenMP offload 
  5. Limitations
    1. Running any GPU code on a Virtual Machine is not supported at this time.
    2. If you have chosen to download the Get Started Guide to use offline, viewing it in Chrome may cause the text to disappear when the browser window is resized. To fix this problem, resize your browser window again, or use a different browser.
    3. Eclipse* 4.12: the code sample project created by IDE plugin from Makefile will not build. It is a known issue with Eclipse 4.12. Please use Eclipse 4.9, 4.10 or 4.11.
