WebThis document assumes proficiency in OpenCL. Data Parallel C++ DPC++ is an open standard-based cross-architecture programming language. The language allows developers to extract high performance from various hardware targets, including CPUs and accelerators such as GPUs and FPGAs. WebThe OpenCL™ execution model includes the concept of work-groups, which represent groups of individual work-items in an NDRange. Work-items in the same work-group are able to share local memory, synchronize using a work-group barrier, and cooperate using work-group functions like async_work_group_copy.
