Details

The work group size chosen by the SYCL runtime for the basic parallel_for kernel launches is suboptimal in some cases. These should be converted to the nd_range version and an appropriate default work group size should be found in each case.

Note: basic parallel_for usage is limited to the sycl-ref backend.

Todo

  • Get baseline performance data for relevant kernels
  • Evaluate performance using nd_range kernel launch
