Prediction of Distributed Volume Visualization Performance to Support Render Hardware Acquisition
(The Eurographics Association, 2017)
We present our data-driven, neural network-based approach to predicting the performance of a distributed GPU volume renderer for supporting cluster equipment acquisition. On the basis of timing measurements from a single ...
High-Performance Mesh Partitioning and Ghost Cell Generation for Visualization Software
(The Eurographics Association, 2016)
Post-processing large datasets efficiently in parallel requires good load balancing of geometry supplied to the visualization pipeline. When datasets are not pre-partitioned or cannot be read back from simulation output ...
Scalable Parallel Feature Extraction and Tracking for Large Time-varying 3D Volume Data
(The Eurographics Association, 2013)
Large-scale time-varying volume data sets can take terabytes to petabytes of storage space to store and process. One promising approach is to process the data in parallel, and then extract and analyze only features of ...
A Task-Based Parallel Rendering Component For Large-Scale Visualization Applications
(The Eurographics Association, 2017)
An increasingly heterogeneous system landscape in modern high performance computing requires the efficient and portable adaption of performant algorithms to diverse architectures. However, classic hybrid shared-memory/distributed ...
Hardware-Accelerated Multi-Tile Streaming for Realtime Remote Visualization
(The Eurographics Association, 2018)
The physical separation of compute resource and end user is one of the core challenges in HPC visualization. While GPUs are routinely used in remote rendering, a heretofore unexplored aspect is these GPUs' special purpose ...
Collaborative High-fidelity Rendering over Peer-to-peer Networks
(The Eurographics Association, 2014)
Due to the computational expense of high-fidelity graphics, parallel and distributed systems have frequently been employed to achieve faster rendering times. The form of distributed computing used, with a few exceptions ...
Performance Modeling of vl3 Volume Rendering on GPU-Based Clusters
(The Eurographics Association, 2014)
This paper presents an analytical model for parallel volume rendering of large datasets using GPU-based clusters. The model is focused on the parallel volume rendering and compositing stages and predicts their performance ...
Dynamically Scheduled Region-Based Image Compositing
(The Eurographics Association, 2016)
Algorithms for sort-last parallel volume rendering on large distributed memory machines usually divide a dataset equally across all nodes for rendering. Depending on the features that a user wants to see in a dataset, all ...
TOD-Tree: Task-Overlapped Direct send Tree Image Compositing for Hybrid MPI Parallelism
(The Eurographics Association, 2015)
Modern supercomputers have very powerful multi-core CPUs. The programming model on these supercomputer is switching from pure MPI to MPI for inter-node communication, and shared memory and threads for intra-node communication. ...
Large-Scale Parallel Visualization of Particle-Based Simulations using Point Sprites and Level-Of-Detail
(The Eurographics Association, 2015)
Recent large-scale particle-based simulations are generating vast amounts of data posing a challenge to visualization algorithms. One possibility for addressing this challenge is to map particles into a regular grid for ...
