Major Features Supported

New in 2024.2.0 

Intel® oneAPI DPC++/C++ Compiler 2024.2.0

  • The Intel® oneAPI DPC++/C++ Compiler added enhanced SYCL Graph capabilities, now featuring pause/resume support for better control and graph profiling to tune for more performance. 
  • The Intel® oneAPI DPC++/C++ Compiler delivers more SYCL performance on Windows with default context enabled. With the latest release the kernel compiler introduces SPIR-V support, and OpenCL* query support, allowing for greater flexibility and optimization in your compute kernels.  

  • Our latest OpenMP enhancements include support for omp_target_memset() and omp_target_memset_async(), enabling developers to efficiently initialize large data on target devices, reducing overhead and accelerating parallel computing tasks. Additionally the compiler emits detailed remarks about OpenMP loop collapsing under the -qopt-report option. Gain valuable insights into your loop transformations and make informed decisions to fine-tune your application's performance.

  • Ensure greater reliability, stability, and security in C++ applications that offload computational tasks to the GPU with the newly added device-side LLVM Address Sanitizer support in Intel® oneAPI DPC++/C++ Compiler to swiftly detect and diagnose memory-related bugs.

Intel® Fortran Compiler 2024.2.0

  • The Intel® Fortran Compiler adds the -fstrict-overflow and Qstrict-overflow[-] options to instruct the Fortran compiler to optimize under the assumption that integer operations won't overflow. For applications that rely on integer overflow behavior, the -fnostrict-overflow option ensures correct functionality.
  • Stay at the forefront of parallel programming with our ongoing conformance enhancements for the latest OpenMP standards, including 5.x and the forthcoming 6.0. With this compiler release you can now specify OpenMP 5.1 THREAD_LIMIT on TEAMS and TARGET constructs to better manage thread usage, and OpenMP 5.2 enhancements like COPYPRIVATE and NOWAIT on construct beginnings, as well as an updated LINEAR clause syntax for more precise control. With OpenMP TR12, the LOOP directive is now applicable to DO CONCURRENT loops, paving the way for more powerful loop optimizations.
  • The added OpenMP runtime library extensions* provide a robust set of memory management extensions, including functions for precise host pointer registration, targeted memory allocations, and device-specific optimizations. With these powerful extensions, you can push the boundaries of performance and efficiency in your high-performance computing applications.

* added extensions: ompx_target_register_host_pointer, ompx_target_unregister_host_pointer, ompx_target_aligned_alloc, ompx-target_aligned_alloc_device, ompx_target_alloc_host, ompx_target_aligned_alloc_shared, ompx_target_aligned_alloc_shared_with_hint, ompx_target_realloc, ompx_target_realloc_device, ompx_target_realloc_host, ompx_target_realloc_shared, ompx_get_device_from_ptr, and ompx_get_num_subdevices.

Intel® Fortran Compiler Classic 2021.13.0

  • The Intel® Fortran Compiler Classic has been updated to include recent versions of 3rd party components, which include functional and security updates.

Intel® MPI Library 2021.13.0

  • On machines with multiple Network Interface Cards (NICs), developers using the Intel® MPI Library now have the option of increased application performance control by pinning specific threads to individual NICs.
  • Developers can now realize faster application performance through optimizations for GPU-aware broadcasts, RMA peer to peer device-initiated communications, intranode thread-splits, and Infiniband tuning for 5th Gen Intel® Xeon® Scalable Processors.

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® 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

  • Patches are built on top of previous patch releases.

Intel® oneAPI DPC++/C++ Compiler 2024.0.2

  • 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.
