Components included in the release

  • clang version 22.1.0
  • SYCL runtime version 9.0.0 (as indicated by predefined macro __LIBSYCL_MAJOR_VERSION, __LIBSYCL_MINOR_VERSION and __LIBSYCL_PATCH_VERSION)

Compatibility with previous releases

This release is compatible with the previous v7.* releases.
Any applications built with these releases should continue to work with runtime shipped in this release.

Compatibility with oneAPI

Intel(R) oneAPI DPC++/C++ Compiler version 2026.1 release leverages codebase from the sycl-rel-7_1 branch and it is the closest oneAPI DPC++/C++ compiler release to this one (in terms of available features and bugfixes).

However, this does not guarantee any feature or bugfix parity between these two releases.

Validation & quality expectations

In general, list of supported hardware and operating systems should match the one provided by Intel(R) oneAPI DPC++/C++ Compiler for version 2026.1, see corresponding system requirements.

However, we did not perform the same exhaustive testing of this open-source branch and therefore there could be some unique issues that are not present in Intel (R) oneAPI DPC++/C++ Compiler version 2026.1.

You can find full validation logs for the branch here but a summary of it will also be posted below.

End to end tests

The following hardware and software configurations were tested:

Driver versions listed as reported by sycl::device::get_info<info::device::driver_version>().

SYCL CTS

Please note that releases made from intel/llvm did not pass the formal Conformance Process defined by the Khronos Group and as such cannot be considered to be fully conformant or fully implementing the SYCL 2020 specification.

  • Linux (Ubuntu 22.04)
    • Intel(R) OpenCL on
      11th Gen Intel(R) Core(TM) i7-1165G7 @ 2.80 Ghz OpenCL 3.0
    • Intel(R) oneAPI Unified Runtime over Level-Zero on
      Intel(R) Iris(R) Xe Graphics 12.0.0
  • Windows
    • Intel(R) oneAPI Unified Runtime over Level-Zero on
      Intel(R) Iris(R) Xe Graphics 12.0.0

We used 493fca2e1f319516c0e9816cd4a714c9c37f1220 CTS in our validation.

How to use

Pre-built binaries are provided for Windows & Linux. Archives contain both SYCL compiler and runtime files.
To use, unpack those and setup PATH & LD_LIBRARY_PATH/PATH & LIB env variables in accordance with
Get Started Guide.

Binaries were built using the following project configuration (below is an (incomplete) list of (key) arguments passed to buildbot/configure.py script):

# Linux:
-t Release --use-zstd --ci-defaults --disable-jit --no-assertions --add_security_flags=sanitize --hip --cuda
# Windows:
--ci-defaults --use-zstd --disable-jit --no-assertions --add_security_flags=sanitize

As you can see, SYCL JIT library is not being built, OpenMP is not being built, HIP & CUDA plugins on Windows are not being built.
If you are interested in a different configuration, you will have to build it yourself. To do so, follow
Get Started Guide

What's Changed

  • Restricted host tasks (sycl::ext::oneapi::experimental::host_task) can now be captured while SYCL Graph native recording mode is active
  • Added command_graph::get_id() to query a process-unique graph ID during SYCL Graph recording
