This book was released on 1997 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, when one considers how visualizations are created in the realm of high performance computing (HPC), the most common model has two distinct phases. Phase one, in which the data is generated and where the role of the supercomputer is simply that of a data firehose spewing forth oceans of data. In phase two, this usually massive amount of data is then transferred to a graphics workstation where an appropriate visualization application is run to produce renderings that will allow for the exploration of the information. Often there are two major problems encountered in this model. First, the data must usually be limited to accommodate the smaller workstation memories (RAM and disk). Second, in many cases the time needed to compute the visual images is unworkably long, making interaction with the visualization impossible. In the model described above the supercomputer is not part of the visualization application at all. Recent technological developments in high speed networks and communication protocols have served to bring high performance computers out of the shadows and into the spotlight with the other components of visualization applications. Tapping the computational power of supercomputers for visualization algorithms and exploiting the high-speed network's ability to move large chunks of data rapidly to and from high performance graphics workstations enables the creation of an environment where distributive, interactive and collaborative visualization applications are possible.

Download or read book Visualization in Supercomputing written by Raul H. Mendez and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: Massive amounts of numeric data are far more comprehensible when converted into graphical form. Hence visualization is becoming an integral part of many areas of research. The idea of visualization is not new, but techniques for visualization are still being developed, and visualization research is just beginning to be recognized as a cornerstone of future computer science. As scientists handle increasingly complex problems with computers, visualization will become an even more essential tool for extracting sense from numbers. This volume is a collection of the best papers selected from those presented at the August 1988 Visualization in Supercomputing Conference in Tokyo, Japan. It is divided into three parts: visualization applications, hardware and performance, and visualization theory. Subjects covered include visualization methods used in computational fluid dynamics research, time-to-solution aspects of visualization, the use of parallel/vector computers with finite element method systems, basic computational performance of two graphics supercomputers, and the applicability of the volume imaging concept in various fields.

Book excerpt: Visualization helps people to understand data and information. Although computers can efficiently process data, human perception is the key to insight and knowledge discoveries. To meet the challenges of increasingly large and complex data, we need methods that effectively integrates high-performance computing techniques and advanced data analytics into interactive visualization systems for allowing comprehension and communication of massive information. This dissertation contributes new methods and frameworks forempowering visualization systems to facilitate interactive and scalable data analysis. PIX is a stack of toolkits based on these methods and frameworks for building high-performance visualization systems. At the foundation is Portable Processing Pipelines (P3), a new declarative visualization language for rapidly specifying data transformations, visual encodings, and interactions to design visualization applications. Picos builds on P3 to provide a concise declarative grammar and a flexible visual interface for designing hierarchical visualizations for exploratory analysis of complex datasets. To provide high performance for interactive visual analysis, PIX exploits multicore CPUs and manycore GPUs to accelerate data processing and visualization rendering. I developed PeerPower, a parallel and distributed computing framework that effectively utilizes multicore CPUs on heterogeneous systems for accelerating data aggregation and visualization. To harness computing power from GPUs for interactive visualizations, I developed P4 by parallelizing P3 via GPU computing for building high-performance visualization systems using declarative grammars. At runtime, P4 automatically creates GPU programs based on declarative specifications to accelerate both data transformations and visualizations. For interactive analysis of large datasets using limited computing resources, a progressive workflow can be used to provide incrementally refining results and allow steering the analysis process by interacting with the intermediate results. By extending P4, I introduced P5 for providing the capability of parallel and progressive visualization. The extended declarative grammars in P5 allow rapid design of scalable systems for progressive and interactive data analysis. In addition to performance and scalability, visualization systems need to incorporate advanced methods for analyzing complex and high-dimensional datasets. To extend PIX with advanced data analytics, I developed P6, a declarative programming toolkit for specifying and integrating machine learning techniques with interactive visualizations. P6 allows interactive systems to richly and effectively combine the capabilities of humans and computers for data analysis and problem-solving. With PIX, different computing technologies, including parallel computing, progressive analytics, and machine learning, can be easily incorporated into interactive visualization systems. By providing toolkits that are both high performance and easy to use, PIX enables more people to build interactive visualization solutions for analyzing big data.

Book excerpt: The research in this dissertation aims to address the challenges to visualization resulting from large and complex datasets. The thesis is that effective high performance visualization, which is responsive to the challenges of large data, follows from a combination of parallel software architectures and optimizations along with steps to reduce processing load in the visualization pipeline. Broadly speaking, the research follows a bifurcated approach. One approach focuses on algorithms and architectures that leverage parallel computing platforms to increase the capacity of the visualization pipeline. Topics in this approach include a sort-first parallel rendering architecture, remote parallel visualization, and the first-ever study of hybrid parallelization of volume rendering at extreme concurrency. The other approach aims to reduce the amount of work entering the visualization pipeline. We coin the term "query-driven visualization" to refer to the process of limiting the amount of data entering the visualization pipeline to that deemed "scientifically interesting," and use state-of-the-art indexing algorithms for rapid data subsetting. This approach has better performance than the best similar algorithms in visualization, and proves useful in diverse applications like forensic cybersecurity analysis and study of output from a high energy physics plasma laser-wakefield simulation code.
Download or read book Visualization in Scientific Computing written by Michel Grave and published by Springer. This book was released on 2011-12-08 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: Visualization in scientific computing is getting more and more attention from many people. Especially in relation with the fast increase of com puting power, graphic tools are required in many cases for interpreting and presenting the results of various simulations, or for analyzing physical phenomena. The Eurographics Working Group on Visualization in Scientific Com puting has therefore organized a first workshop at Electricite de France (Clamart) in cooperation with ONERA (Chatillon). A wide range of pa pers were selected in order to cover most of the topics of interest for the members of the group, for this first edition, and 26 of them were presented in two days. Subsequently 18 papers were selected for this volume. 1'he presentations were organized in eight small sessions, in addition to discussions in small subgroups. The first two sessions were dedicated to the specific needs for visualization in computational sciences: the need for graphics support in large computing centres and high performance net works, needs of research and education in universities and academic cen tres, and the need for effective and efficient ways of integrating numerical computations or experimental data and graphics. Three of those papers are in Part I of this book. The third session discussed the importance and difficulties of using stan dards in visualization software, and was related to the fourth session where some reference models and distributed graphics systems were discussed. Part II has five papers from these sessions.
Download or read book Interfacing Parallel Scientific Applications with Multiple Visualization Systems written by and published by . This book was released on 1998 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: As high-performance computer simulation increasingly replaces more expensive and time-consuming conventional alternatives, namely physical prototyping/experimentation, it becomes important to provide mechanisms for interacting with parallel or distributed simulation programs. Such interactive exchanges can close the loop on simulation experiments by providing visualization of intermediate results and then allowing scientists to respond by manipulating the simulation, while it is running. This type of visualization and computation steering feedback system can dramatically shorten the experimental cycle by pruning off experiments that are quickly seen to be undesirable. Further, such interaction can provide enhanced capabilities for what if analyses, even beyond what would be possible in a physical environment. This approach also introduces new forms of collaboration, by allowing multiple remote collaborators to cooperate and interact via the running simulation programs, each person exploring their own view of the data and then sharing their understanding with the group. The CUMULVS (Collaborative User Migration User Library for Visualization and Steering) system is a middleware library infrastructure that allows multiple, potentially remote, scientists to monitor and coordinate control over a parallel simulation program. Using CUMULVS, various front-end viewers can dynamically attach to a simulation to view snapshots of the ongoing computation, or manipulate (steer) parameters of the simulation, and then detach. The snapshots of intermediate data array values can be rendered using a variant of visualization systems, including AVS, Tcl/Tk, and VTK, or as simple text dumps. CUMULVS provides the interfacing between the simulation tasks and the visualization systems, and transparently handles the viewer connection protocols and the data collection required for decomposed or distributed data. CUMULVS also provides mechanisms for developing fault-tolerant applications in heterogeneous distributed computing environments.
