Advanced Visual Systems Inc. 300 Fifth Ave. Waltham, MA 02154 3333333333333333333AVS Modules NAME AVS modules ± introduction to manual pages for AVS modules DESCRIPTION This man page summarizes all modules available with the AVS distribution in alpha- betical order. The individual module man pages follow in alphabetical order. The manual pages are also available on-line. You can view them within AVS by clicking on the small square "dimple" in any module icon with the middle or right mouse button to open its Module Editor window. Then click the Show Module Documentation button to view the complete manual page for the module. They may also be seen using the regular help browser, in the following directory: $AVS_PATH/runtime/help/modules MODULE LIBRARIES Modules are organized into module libraries for easy interactive access. By default, these module libraries appear when you ®rst start AVS: Supported Imaging Volume UCD FiniteDiff Animation (if present on your system) Chemistry Unsupported All modules are in the Supported module library except Animation, Chemistry, and the Unsupported modules. Any one module can be in multiple module libraries. At the top of each module's man page there is an "Availability" line that lists which module libraries the module can be found in, in addition to the default Supported library. Each module library is described on its own man page. INPUT/OUTPUT DATA TYPE NOTATION The data-types that AVS modules operate on are described in the "Importing Data into AVS" chapter of the AVS User's Guide, and in the AVS Developer's Guide in the chapter, "AVS Data Types". Throughout the manual pages for AVS modules, a number of terms are used to describe these data types. It is important to understand these terms, as they specify what inputs a given module can receive, and what out- puts it will generate. any-dimension: when a module accepts ®elds of any-dimension, this means that it can process ®elds that are 1D, 2D, 3D, and in some cases 4D; but never more than this. n-vector: if a ®eld has one value at each location, it is a scalar ®eld. When a module accepts n-vector ®elds, it can receive ®elds with an indeterminate number of values at each location. any-data: if a module accepts any-data, this means it can receive byte, short, integer, ¯oat, or double data. If it is more restrictive, this will be declared. any-coordinates: if a module accepts data of any-coordinates, this means that it can operate on 33333333333333333333333333®elds which have uniform, rectilinear, or irregular coordinates. If a module AVS Module Reference Manual 1 AVS3333333333333333333 Modules cannot operate on one of these types of ®eld, this will be declared. PLATFORM DEPENDENCE Some mapper modules required specialized graphics rendering support such as 3D texture mapping (brick, excavate brick, etc.) and object transparency (alpha blend, volume render, etc.). This specialized rendering support can be provided in software (via the software renderer), or by hardware. However, not all hardware rendering platforms support all specialized rendering features. The hardware rendering features available on your platform should be de®ned in a table in the release notes that accompany the AVS software product for that platform. The software renderer supports most specialized rendering features except vertex tran- sparency. Each module with specialized rendering requirements has an "Availability" notation near the top of its module man page that de®nes the support needed. If your renderer does not support the function, the picture will not appear as documented. For example, a texture-mapped object will appear as an uncolored, featureless object. Transparent objects will be opaque, or not drawn at all. You can almost always acquire the specialized rendering support by switching on the Software Renderer option on the Geometry Viewer's Cameras submenu. If no such selection appears on the Cameras submenu, it means that the software renderer is probably the only renderer available and is already performing rendering functions in the AVS Geometry Viewer.

  • Overview of Recent Supercomputers
    Overview of recent supercomputers Aad J. van der Steen high-performance Computing Group Utrecht University P.O. Box 80195 3508 TD Utrecht The Netherlands [email protected] www.phys.uu.nl/~steen NCF/Utrecht University July 2007 Abstract In this report we give an overview of high-performance computers which are currently available or will become available within a short time frame from vendors; no attempt is made to list all machines that are still in the development phase. The machines are described according to their macro-architectural class. Shared and distributed-memory SIMD an MIMD machines are discerned. The information about each machine is kept as compact as possible. Moreover, no attempt is made to quote price information as this is often even more elusive than the performance of a system. In addition, some general information about high-performance computer architectures and the various processors and communication networks employed in these systems is given in order to better appreciate the systems information given in this report. This document reflects the technical state of the supercomputer arena as accurately as possible. However, the author nor NCF take any responsibility for errors or mistakes in this document. We encourage anyone who has comments or remarks on the contents to inform us, so we can improve this report. NCF, the National Computing Facilities Foundation, supports and furthers the advancement of tech- nical and scientific research with and into advanced computing facilities and prepares for the Netherlands national supercomputing policy. Advanced computing facilities are multi-processor vectorcomputers, mas- sively parallel computing systems of various architectures and concepts and advanced networking facilities.

Dongarra Electrical Engineering and Computer Science Department University of Tennessee Knoxville, TN 37996-1301 Computer Science and Mathematics Division Oak Ridge National Laboratory Oak Ridge, TN 37831 University of Manchester June 15, 2014 Abstract This report compares the performance of different computer systems in solving dense systems of linear equations. The comparison involves approximately a hundred computers, ranging from the Earth Simulator to personal computers. 1. Introduction and Objectives The timing information presented here should in no way be used to judge the overall performance of a computer system. The results reflect only one problem area: solving dense systems of equations. This report provides performance information on a wide assortment of computers ranging from the home-used PC up to the most powerful supercomputers. The information has been collected over a period of time and will undergo change as new machines are added and as hardware and software systems improve.

Benton Chairman, Departmental Committee on Graduate Students Multiple Viewpoint Rendering for Three-Dimensional Displays by Michael W. Halle Submitted to the Program in Media Arts and Sciences, School of Architecture and Planning on March 14, 1997, in partial fulfillment of the requirements for the degree of Doctor of Philosophy Abstract This thesis describes a computer graphics method for efficiently rendering images of static ge- ometric scene databases from multiple viewpoints. Three-dimensional displays such as parallax panogramagrams, lenticular panoramagrams, and holographic stereograms require samples of im- age data captured from a large number of regularly spaced camera images in order to produce a three-dimensional image. Computer graphics algorithms that render these images sequentially are inefficient because they do not take advantage of the perspective coherence of the scene. A new algorithm, multiple viewpoint rendering (MVR), is described which produces an equivalent set of images one to two orders of magnitude faster than previous approaches by considering the image set as a single spatio-perspective volume.

  • Expressiveness, Programmability and Portable High Performance of Global Address Space Languages
    RICE UNIVERSITY Expressiveness, Programmability and Portable High Performance of Global Address Space Languages by Yuri Dotsenko A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE Doctor of Philosophy APPROVED, THESIS COMMITTEE: Dr. John Mellor-Crummey, Chair Associate Professor of Computer Science Dr. Ken Kennedy John and Ann Doerr University Professor of Computational Engineering Dr. Peter Joseph Varman, Professor of Electrical & Computer Engineering HOUSTON, TEXAS JANUARY, 2007 Expressiveness, Programmability and Portable High Performance of Global Address Space Languages Yuri Dotsenko Abstract The Message Passing Interface (MPI) is the library-based programming model employed by most scalable parallel applications today; however, it is not easy to use. To simplify program development, Partitioned Global Address Space (PGAS) languages have emerged as promising alternatives to MPI. Co-array Fortran (CAF), Titanium, and Unified Parallel C are explicitly parallel single-program multiple-data languages that provide the abstraction of a global shared memory and enable programmers to use one-sided communication to access remote data. This thesis focuses on evaluating PGAS languages and explores new language features to simplify the development of high performance programs in CAF. To simplify program development, we explore extending CAF with abstractions for group, Cartesian, and graph communication topologies that we call co-spaces. The com- bination of co-spaces, textual barriers, and single values enables effective analysis and optimization of CAF programs. We present an algorithm for synchronization strength re- duction (SSR), which replaces textual barriers with faster point-to-point synchronization. This optimization is both difficult and error-prone for developers to perform manually. SSR-optimized versions of Jacobi iteration and the NAS MG and CG benchmarks yield performance similar to that of our best hand-optimized variants and demonstrate signifi- cant improvement over their barrier-based counterparts.
