Image and data-parallel rendering across multiple nodes on HPC systems is widely used in visualization to provide higher framerates, support large datasets, and render data in situ. Specifically for in situ, reducing bottlenecks incurred by the visualization and compositing tasks is of key concern to reduce the overall simulation run time. Moreover, prior algorithms have been designed to support either image or data-parallel rendering, and impose restrictions on the data distribution, requiring different implementations for each configuration. In this paper, we introduce the Distributed FrameBuffer, an asynchronous image-processing framework for multi-node rendering. We demonstrate that this approach achieves performance superior to the state of the art for common use cases, while providing the flexibility to support a wide range of parallel rendering algorithms and data distributions. By building on this framework, we extend the open-source ray tracing library OSPRay with a data-distributed API, enabling its use in data-distributed and in situ visualization applications.
