Streami: An MPI Data-Parallel Library to Compute Field Lines on GPUs
Stefan Zellmann, Milan Jaros, Andrea Paris +2
We present Streami, an extensible GPU-accelerated library for the computation of field lines in fluid flows on high-performance computers. Streami acts as a thin layer used for bot…
RAFI -- A Ray/Work Forwarding Infrastructure for Data Parallel Multi-Node/Multi-GPU Computing
Ingo Wald, Serkan Demirci, Alper Sahistan +7
We present RaFI, a CUDA and MPI based software framework that simplifies the task of building GPU-enabled data-parallel software where rays or similar work items need to migrate be…
GPU Volume Rendering with Hierarchical Compression Using VDB
Stefan Zellmann, Milan Jaros, Jefferson Amstutz +1
We propose a compression-based approach to GPU rendering of large volumetric data using OpenVDB and NanoVDB. We use OpenVDB to create a lossy, fixed-rate compressed representation…
Data Parallel Visualization and Rendering on the RAMSES Supercomputer with ANARI
Stefan Zellmann
3D visualization and rendering in HPC are very heterogenous applications, though fundamentally the tasks involved are well-defined and do not differ much from application to applic…
Standardized Data-Parallel Rendering Using ANARI
Ingo Wald, Stefan Zellmann, Jefferson Amstutz +4
We propose and discuss a paradigm that allows for expressing \emph{data-parallel} rendering with the classically non-parallel ANARI API. We propose this as a new standard for data-…
