Bridging CPUs and GPUs with std::execution - Using Senders / Receivers as a Frame Graph
Al-Afiq Yeong
The Directed Acyclic Graph (DAG) is a quintessential data structure in modern rendering engines and is commonly referred to as a Frame Graph in the industry. Their usage allows us to minimize barriers on image and buffer resources, maximizing transient resource usage and enables efficient GPU work recording. This talk explores whether C++’s std::execution can serve as a viable foundation for a renderer’s frame graph. We’ll examine how well senders/receivers map onto the requirements of a modern GPU scheduling system and whether they can replicate the capabilities of conventional frame graph implementations. By the end, attendees will understand the strengths, limitations, and practical feasibility of building a rendering frame graph on top of std::execution, along with the trade-offs compared to conventional implementations.
