SYCL-Based Kernel Templates
The SYCL kernel templates are based on the SYCL 2020 programming model of Intel® oneAPI DPC++/C++ Compiler. Kernel templates may impose restrictions on supported devices or adapters which are documented in their respective sections.
Kernel Parameter Interpretation
The definition of a work-item as it relates to kernel_param parameters directly aligns with the SYCL specification. With the Intel® oneAPI DPC++/C++ Compiler, a work-item corresponds to a SIMD lane on SIMD architecutes and a thread on SIMT architectures.
NOTE:
If migrating from ESIMD kernel templates, then dividing ESIMD data_per_workitem by 32 approximates the SYCL data_per_workitem and multiplying ESIMD workgroup_size by 32 approximates the SYCL workgroup_size on Intel GPUs. However, configurations from one model may not be supported by the other, and optimal parameters should be determined through performance testing.
Available Templates
The following templates are available in the oneapi::dpl::experimental::kt::gpu namespace, with the implementation optimized for GPU devices:
