BabelStream Versions Save

v5.0 contains a few bug fixes in the CMake build system, but the key new features are:

• Additional programming models, including Fortran, SYCL 2020 with Unified Shared Memory, and Futhark
• Reporting of performance of the array initialisation and copy back of solutions to the host that happen before and after (respectively) of the main benchmarking.
• Preliminary support for building with Spack.

Find out more in our blog post.

This update adds new implementations in parallel programming models, including ISO C++, SYCL 2020, TBB and Thrust. We also include new standalone implementations in the Julia, Rust and Scala languages. Our build system has been updated to use CMake exclusively, and provides recommended build parameters for major compilers for all programming models.

For more details, please see the accompanying blog post.
