Does raja support SYCL？

[artv3]

There is some support with RAJA forall and launch API's. I believe reductions are not fully supported yet.
Please see the following examples:

https://github.com/LLNL/RAJA/blob/develop/exercises/vector-addition.cpp
https://github.com/LLNL/RAJA/blob/develop/examples/dynamic_mat_transpose.cpp

Actually, all RAJA::forall and most RAJA::kernel and RAJA::launch features are supported in the develop branch. SYCL reduction support is being developed in https://github.com/LLNL/RAJA/tree/feature/homerdin/sycl_reduction. Parallel scans and sorts are not available yet. Available execution policies, etc. for SYCL are described in the RAJA User Guide.

I am not familiar with raja. What is the meaning of reductions?

[rhornung67]

Parallel reduction is a general computer science topic, supported by RAJA but not RAJA-specific: https://en.wikipedia.org/wiki/Reduction_operator

The main RAJA project page on GitHub contains a link to the RAJA User Guide. Please refer to that to learn about RAJA. If you have questions, please let us know.
