Explore the world of Single Instruction Multiple Data (SIMD) libraries in C++ through this comprehensive conference talk from CppNow 2023. Delve into the evolution of vector processing and its impact on modern computing. Learn about the challenges of compiler vectorization and the shift towards direct SIMD utilization in algorithms. Discover application-level libraries for JSON parsing, compression, and CRC processing that leverage SIMD capabilities. Examine 'developer libraries' that provide abstractions for creating new parallel algorithms. Get an introduction to the proposed std::simd for C++26, including data-parallel types, related traits, and Abi facilities. Understand the design choices and trade-offs made by various SIMD libraries. Gain insights into accessing preliminary implementations through GCC11 and later versions. Prepare for hands-on experience with writing parallel algorithms using std::simd in the associated Library in a Week session.
