This video lecture introduces distributed parallelism using the HPX framework. The lecturer reviews the single program multiple data (SPMD) and Communicating Sequential Processes (CSP) models, then focuses on practical implementation using HPX, including point-to-point and collective communication examples. The lecture also covers data partitioning, serialization, and the use of communicators within HPX.
broadcast and reduce functions for collective communication, essential for distributing parameters and aggregating results across nodes.serialize function for custom types is shown.
