C++ Performance Portability - A Decade of Lessons Learned - Lecture

Explore a decade of challenges and lessons learned in developing Kokkos, a C++ based Performance Portability EcoSystem, in this CppCon 2022 conference talk. Dive into key challenges for designing performance portable software and learn how to address them through appropriate API design. Discover how fundamental concepts for performance portability are being introduced into the ISO C++ standard through upcoming features. Gain insights into scientific computing's evolving landscape, including the need to account for diverse hardware and programming model environments such as CUDA, HIP, SYCL, and OpenMP. Understand how performance portability solutions like Kokkos enable developers to write code once and execute it efficiently on any HPC platform, relieving domain experts from becoming experts in multiple vendor-provided ecosystems.
