DATA PARALLEL VISUALIZATION AND RENDERING ON THE RAMSES SUPERCOMPUTER WITH ANARI

3D visualization and rendering in HPC are very heterogenous applications, though fundamentally the tasks involved are welldefined and do not differ much from application to application. The Khronos Group’s ANARI standard seeks to consolidate 3D rendering across sci-vis applications. This paper makes an effort to convey challenges of 3D rendering and visualization with ANARI in the context of HPC, where the data does not fit within a single node or GPU but must be distributed. It also provides a gentle introduction to parallel rendering concepts and challenges to practitioners from the field of HPC in general. Finally, we present a case study showcasing data parallel rendering on the new supercomputer RAMSES at the University of Cologne.
