std::simd how to express inherent parallelism efficiently via data-parallel types Dr. Matthias Kretz GSI Helmholtz Center for Heavy Ion Research CppCon ’23 @mkretz@floss.social github.com/mattkretzMotivation instructions/registers! consider SIMD an implementation-detail of data-parallelism We failed to express the “interesting” parallelism. Instead we expressed only 4 independent values and had to reduce to ResearchMotivation std::simd Overview Example: Image Processing Programming Models Outlook Summary How to express data-parallelism? Idea: Every pixel can be processed independently. ⇒ Process as many pixels in
