The implementation allows a flexible combination of parallel simulation, concurrent parallel analysis and GUI client, all of which may be on the same or separate machines. Data transfer between the simulation and the ParaView server takes place using a virtual file driver for HDF5 that bypasses the disk entirely and instead communicates directly between the coupled applications in parallel. The simulation and ParaView tasks run as separate MPI jobs and may therefore use different core counts and/or hardware configurations/platforms, making it possible to carefully tailor the amount of resources dedicated to each part of the workload. The coupled applications write and read datasets to the shared virtual HDF5 file layer, which allows the user to read data representing any aspect of the simulation and modify it using ParaView pipelines, then write it back, to be reread by the simulation (or vice versa). This allows not only simple parameter changes, but complete remeshing of grids, or operations involving regeneration of field values over the entire domain, to be carried out. To avoid the problem of manually customizing the GUI for each application that is to be steered, we make use of XML templates that describe outputs from the simulation, inputs back to it, and what user interactions are permitted on the controlled elements. This XML is used to generate GUI and 3D controls for manipulation of the simulation without requiring explicit knowledge of the underlying model.","PeriodicalId":90824,"journal":{"name":"Eurographics Symposium on Parallel Graphics and Visualization : EG PGV : [proceedings].

One solution that meets these requirements is to store a compact intermediate representation of the data, instead of a 3D volume itself. Recent work explores the use of attenuation functions as a data representation that summarizes the distribution of attenuation along the rays. This representation goes beyond conventional static images and allows users to dynamically explore their data, for example, to change color and opacity parameters, without accessing the original 3D data. The computation and storage costs of this method may still be prohibitively expensive for large and time-varying data sets, thus limiting its applicability in the real-world scenarios. In this paper, we present an efficient algorithm for computing attenuation functions in parallel. We exploit the fact that the distribution of attenuation can be constructed recursively from a hierarchy of blocks or intervals of the data, which is a highly parallelizeable process. We have developed a library of routines that can be used in a distance visualization scenario or can be called directly from a simulation code to generate explorable images in-situ. Through a number of examples, we demonstrate the application of this work to large-scale scientific simulations in a real-world parallel environment with thousands of processors. We also explore various compression methods for reducing the size of the RAF. Finally, we present a method for computing an alternative RAF representation, which more closely encodes the actual distribution of samples along a ray, using kernel density estimation.","PeriodicalId":90824,"journal":{"name":"Eurographics Symposium on Parallel Graphics and Visualization : EG PGV : [proceedings].

The aim of KoDaVis is the visualisation of huge data sets from atmosphere research. The core of the presented distributed computer supported collaborative work system is a framework for the coupling of heterogeneous visualisation systems and the design and implementation of two distinct servers, one for the collaborative aspects and one for the direct remote access to centrally stored data. Interfaces to the VTK-based virtual reality visualisation system ViSTA and to the modular visualisation environment AVS/Express were implemented and tested. The successful coupling of these two different visualisation systems as well as the benefit of a fast optical network for parallel data access and for distributed collaboration could be demonstrated in a test setup.","PeriodicalId":90824,"journal":{"name":"Eurographics Symposium on Parallel Graphics and Visualization : EG PGV : [proceedings].
