Parallel programming paradigms have been adapted to ever-changing computing resources, needs and goals over the course of history. The evolution of high-end computer architecture (from organic to mechanical to digital and from single-core computers to vector-based, multicore-based, and hybrid CPU/GPGPU-based machines) has necessitated the continuing development of new parallel programming paradigms and numerical algorithms. In this talk, I discuss the development of numerical algorithms throughout the history of numerical computing placed within their historical and architectural contexts, and the implications of future architectures on numerical methods.
