WebClang supports OpenMP target offloading to several different architectures such as NVPTX, AMDGPU, X86_64, Arm, and PowerPC. Offloading code is generated by Clang and then executed using the libomptarget runtime and the associated plugin for the target architecture, e.g. libomptarget.rtl.cuda. WebTARGET CONSTRUCT §Marks code for offload onto a device §When a host thread reaches a target construct, the host thread execution pauses (by default) and a single initial thread executes the target region on the default device §Clauses to control behavior, like nowaitand device 11 host thread #pragma omptarget #pragma omptarget { C = A + B; }
