Intel SYCL Compiler release 6.2.0
AlexeySachkov
Alexey Sachkov
Components included in the release
- clang version
21.0.0 - SYCL runtime version 8.0.0 (as indicated by predefined macro
__LIBSYCL_MAJOR_VERSION,__LIBSYCL_MINOR_VERSIONand__LIBSYCL_PATCH_VERSION)
Compatibility with previous releases
This release is compatible with previous v6.0.1 and v6.1.0 releases.
Any applications built with those releases should continue to work with runtime shipped in this release.
Compatibility with oneAPI
Intel(R) oneAPI DPC++/C++ Compiler version 2025.2 release leverages codebase from the sycl-rel-6_2 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 2025.2, 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 2025.2.
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>().

We used 87f8677c 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 a list of arguments passed to buildbot/configure.py script):
# Linux:
-t Release --ci-defaults --disable-jit --no-assertions --add_security_flags=sanitize --hip --cuda
# Windows:
--ci-defaults --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
Changes since v6.1.0
