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…
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-…
