Single Work-item Kernels

When a kernel describes a single work item, the DPC++ host can execute the kernel as a single task. The SYCL* specification version 1.2.1 describes this mode of operation as task-parallel programming. A task is equivalent to a kernel executed with one work-group that contains one work-item. For more information, refer to Concepts of Hardware Design and Mapping Parallelism Models to Hardware.

Product and Performance Information


Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
