Intel® oneAPI DPC++/C++ Compiler 2024.1.0
- The Intel® oneAPI DPC++/C++ Compiler is the industry's first compiler conformant with SYCL 2020 allowing developers to write code once and run it on a variety of different processors using standard C++ making developers more productive by reducing development time and effort.
- Enhanced SYCL Graph, allowing developers to use multi-threaded work generation and thread-safe functions seamlessly integrate with applications. SYCL ensures thread safety for all member functions, enhancing performance and reliability in parallel computing. SYCL Graph is now available on multiple SYCL backends, allowing developers to tune once and deploying anywhere. Additionally, our CUDA graph alternative offers and open, multi-platform solution, minimizing kernel dispatching overhead and ensuring adaptability across diverse software and hardware stacks.
-
Intel® oneAPI DPC++/C++ Compiler enhances OpenMP 5.0, 5.1, 5.2, and TR12 standards compliance.
Intel® Fortran Compiler 2024.1.0
- Intel® Fortran Compiler adds more Fortran 2023 language features - improving compatibility and interoperability between C and Fortran code in the intrinsic module ISO_C_BINDING; simplifying trigonometric calculations by allowing developers to use intrinsic functions that accept arguments as degrees, enhancing ease of use and code readability; use of predefined data types of specific sizes in intrinsic module ISO_FORTRAN_ENV improving code portability and ensuring consistent behavior, and more.
- Intel® Fortran Compiler makes OpenMP Offload programming more productive by adding runtime checks ensuring that mapped data is currently allocated/associated.
- Increased compiler stability by fixing miscellaneous compilation, OpenMP* and runtime issues.
Intel® Fortran Compiler Classic 2021.12.0
- The Intel® Fortran Compiler Classic has been updated to include recent versions of 3rd party components, which include functional and security updates.
New in 2024.0.1

- Patches are built on top of previous patch releases.
Intel® oneAPI DPC++/C++ Compiler 2024.0.2
- Bug fixes including those in Intel® oneAPI DPC++/C++ Compiler 2024.0.1
Intel® Fortran Compiler 2024.0.2
- Bug fixes including those in Intel® Fortran Compiler 2024.0.1
Intel® Fortran Compiler Classic 2021.11.1
- A deprecation message is added to the ifort command
New in 2024.0.0
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 5th Generation of Intel® 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.
- 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++/C++ Compiler 2024.0.1
