The algorithm runs across heterogeneous architectures of PC-clusters consisting of a visualization-node, equipped with a powerful graphics adapter, and cluster nodes requiring weaker graphics capabilities only. The visualization-node renders a mixture of scene objects and simplified meshes (Reliefboards). The cluster nodes assist the visualization-node by asynchronous computing of Reliefboards, which are used to replace and render distant parts of the scene. Our algorithm is capable of gaining significant speedups if the cluster's nodes provide weak graphics adapters only. We trade the number of cluster nodes off the scene objects' image quality.}}, author = {{Fischer, Matthias and Jähn, Claudius and Suess, Tim}}, booktitle = {{Eurographics Symposium on Parallel Graphics and Visualization (EGPGV)}}, pages = {{43--51}}, publisher = {{The Eurographics Association}}, title = {{{Asynchronous Parallel Reliefboard Computation for Scene Object Approximation}}}, doi = {{10.2312/EGPGV/EGPGV10/043-051}}, year = {{2010}}, } @inproceedings{18289, abstract = {{Many professional cluster systems consist of nodes with different hardware configurations. Such heterogeneous environments require different load-balancing techniques than homogenous environments. The c-load-collision-protocol is able to achieve good results for data-management purposes. Using this protocol, we propose a way for load-balancing in interactive rendering environments. For this work, we implemented a parallel rendering system and took different picking strategies into account to compare the results. The advantage of our approach compared to other approaches is that we group the available nodes of a cluster into two different categories, based on the hardware abilities. Some nodes are used solely for rendering, while others serve as secondary storage and to assist the former ones by performing auxiliary calculations.}}, author = {{Suess, Tim and Wiesemann, Timo and Fischer, Matthias}}, booktitle = {{2010 IEEE Fifth International Conference on Networking, Architecture, and Storage}}, isbn = {{9781424481330}}, pages = {{448 -- 456}}, title = {{{Evaluation of a c-Load-Collision-Protocol for Load-Balancing in Interactive Environments}}}, doi = {{10.1109/nas.2010.52}}, year = {{2010}}, } @inbook{18290, abstract = {{Typischerweise sind die Knoten eines PC-Clusters nicht mit leistungsfähigen Grafikkarten ausgestattet.
