CEI awarded SBIR Phase I for 'Co-Processing for Complex Unsteady CFD Simulations'

APEX, N.C. (December 4, 2007) – Computational Engineering International Inc. (CEI) was recently awarded a Small Business Innovation Research (SBIR) Program Phase I Award from the United States Army.

The purpose of the project is to research and determine the technical merit or feasibility of CFD Co-processing for Unsteady Visualization. Co-processing remains a seldom-used method to post-process simulations both because of gains in computing speed and storage capacity, and the lack of reliable, robust automated flow feature extraction methods. Due to the size of these large, complex, transient solutions, a shift towards co-processing technology is required. CEI will research adapting it’s high performance and flexible EnSight post processing system for the purpose of co-processing these large and complex simulations.

Under the SBIR, CEI will investigate the feasibility of periodically reviewing results as the solver computes them, which may require days or even weeks of processing time.

Mark Potsdam, Aerospace Engineer with the US Army, AFDD, and project manager of the SBIR Phase I award said, “The US Army Aeroflightdynamics Directorate is looking forward to working with CEI to significantly enhance our CFD post-processing capabilities. The co-processing capabilities that CEI will develop and demonstrate in this SBIR will drastically reduce the manpower and time required to visualize large-scale, time-dependent rotorcraft CFD datasets.”

“CEI is always looking for new challenges that we can apply our expertise and current technology towards solving. I am confident that we will find and propose a robust and high performance solution to the U.S. Army under the Phase I SBIR,” said Anders Grimsrud, president of CEI.

Karbon to Present Virtual Automotive Design Techniques During Keynote at CEIViz 2008 Conference

APEX, N.C., August 7, 2008 –Kenneth Karbon, performance engineer at General Motors Vehicle Engineering, will be the keynote speaker at the second biennial CEIViz ‘08 conference. CEIViz ‘08 is the international conference for high-performance visualization. The conference will be held at the Radisson Lord Plaza Hotel in Baltimore, MD, September 23-25, 2008.

Karbon’s presentation will focus on simulation and visualization in automotive design. Automotive design and engineering has a rich history of hardware testing and development. Major automakers have an extensive network of styling studios, proving grounds, test labs, and prototype shops. These hands-on methods will always be necessary in some form for automotive designers to deliver a final product that meets the expectations of customers who are equally passionate about the vehicles they drive.

“Automotive engineering performance is governed by numbers like miles per gallon, drag coefficient, and stopping distance, says Karbon. However, to connect with our partners in styling and design, we need to bring those numbers to life with effective visual communication.”

Globalization of the auto market and compressed product cycles pushed the limits of physical testing capability and brought computer methods to the mainstream. Simulations are well established in the vehicle development process, supplementing experiments or eliminating them altogether in order to maximize engineering throughput. Karbon’s presentation will summarize General Motors’s use of virtual tools in styling, CAD, CAE, and collaboration, including visualization successes with EnSight.

Mississippi State University Purchases New Academic License for CEI's EnSight

APEX, N.C. (May 8, 2007) – Computational Engineering International (CEI) announced today that Mississippi State University is the first institution to license the company’s EnSight visualization software through its new and flexible academic licensing options. The new pricing options provide qualified academic institutions with an EnSight license for either a specific course or for the entire campus. EnSight is an industry-leading extreme visualization tool for the scientific and engineering community, and is used by researchers worldwide in a wide variety of industries and research areas.

“Our new class and campus academic licenses offer universities EnSight’s industry-leading visualization capabilities through specially priced plans that respond to the needs of academia,” said Darin McKinnis, CEI’s vice president of marketing and sales. “And we’re particularly pleased to see our first academic license go to Mississippi State University, where EnSight will serve an impressive variety of fields and disciplines at three of the school’s computational research centers.”

Mississippi State University’s campus license will cover four of the research centers that are part of the University’s High Performance Computing Collaboratory (HPC2). The centers include the Computational Simulation and Design Center (SimCenter); the Center for Advanced Vehicular Systems (CAVS); the GeoResources Institute (GRI); and the Center for Computational Sciences (CCS). As part of the HPC2, these centers are involved in research that advances the state of the art in computational science and engineering using high-performance computing for applications ranging from aerospace to geospatial technologies.

The decision to purchase a campus license was prompted in part by the need for a commercially supported post-processing tool that would serve as a standard throughout the research facilities. Formerly, the University relied on an open-source application. The new license includes EnSight, EnSight Gold, and EnSight DR.

“EnSight not only provides for the visualization needs of our computational research facilities, but it also responds to our specialized computing demands,” said Dr. Eric Blades, Assistant Research Professor Mississippi State’s SimCenter. “Our campus license makes it possible—and affordable—for us to work on desktops, to process large-scale computations in parallel, and to call on powerful distributed rendering capabilities for our immersive virtual environment.”

The new academic licenses offer extraordinary computing flexibility to academic facilities. EnSight’s flexible architecture supports the mixing of computer platforms within a single visualization session, within a workgroup, or even across a university’s entire network. In addition, all EnSight licenses are floating, meaning that EnSight can be installed and run on any computer within the local network. To run EnSight, users at a licensed academic institution can simply install the application and contact the network administrator to obtain the license key to use the software.

Both campus and class licenses are available either on an annual or perpetual basis. One year’s maintenance and support are included with both the annual and perpetual licenses.

NASA Ames purchases EnSight Gold licenses to enhance visualization quality, collaboration

APEX, N.C., August 1, 2006 – NASA Ames Research Center has purchased multiple licenses of CEI’s EnSight Gold software to provide consistent visualization quality for different types of analyses and to support collaboration among different NASA divisions, the Department of Defense (DoD), and the Department of Energy (DoE).

Several factors played a part in the decision to purchase EnSight Gold:
It provides visual analyses of many types of data in many different formats.
It can operate in client-only or client-server mode.
It supports a mixed computing environment such as the NASA Ames Columbia supercomputer cluster and Apple Macintosh desktop clients.
It supports remote collaboration.
It enables easy output to rich media, including file formats that can be run in QuickTime and edited in Final Cut Pro on the Mac.
It allows NASA Ames to leverage the large EnSight user base already established within NASA, DoD and DoE.
It provides an open, high-performance file format for all types of CFD and structural analysis.

Parallel-server and client-server functionality within EnSight Gold is also important to NASA Ames. Parallel-server functionality provides interactive access to multiple CPUs that speed visualization for compute-intensive problems or problems involving a large number of datasets. Client-server mode allows NASA Ames to take advantage of large compute platforms to provide fast display for remote users doing visualization on a Mac or Linux system.

The first EnSight Gold project for NASA Ames is visualizing time-dependent analyses of debris trajectory as part of the Return to Flight initiative. In the near future, NASA Ames plans to use EnSight Gold in development of the Crew Launch Vehicle (CLV), designed to deliver the Crew Exploration Vehicle (CEV) to low-Earth orbit early next decade, and the shuttle-derived heavy-lift launcher.

General Motors of Brazil purchases EnSight to better understand, communicate simulation results

APEX, N.C., April 10, 2006 – General Motors of Brazil (GMB) has purchased three licenses of CEI’s EnSight to visualize, analyze and communicate simulation results from the company’s Vehicle Synthesis, Analysis and Simulation (VSAS) division. The sale was made by Engineering Simulation and Scientific Software (ESSS), CEI’s South American distributor and Brazil’s leading supplier of computational fluid dynamics (CFD) and finite element analysis (FEA) solutions.
“EnSight gives us good tools to support problem analysis and generate animations that improve communication within our engineering community,” says Roberto P. Ramos, VSAS manager at General Motors of Brazil. “The high-quality animations that we can create in EnSight and the ability to compare different case scenarios is integral to our work.”
GMB VSAS uses EnSight to visualize simulation results for a wide variety of analyses, including structural, aero/thermal, NVH, durability, vehicle dynamics, safety, and electrical/electronics. EnSight provides readers that enable GMB VSAS to easily import results from its Fluent, Abaqus and LS-Dyna solvers.
Ramos considers EnLiten, CEI’s free geometry viewer, “very important” to VSAS’s work. EnLiten is a collaborative visualization tool that enables EnSight users to save their work in a scenario file that includes the actual EnLiten application. The file is sent via e-mail or posted on a web site for downloading by associates, who use EnLiten’s simple graphics interface to manipulate 3D models and view animations from different perspectives.
“EnLiten helps analysts better understand simulation results and explain them visually to other decision- makers at the beginning of the development phase,” says Ramos.

Blondin to present Supernova Simulations during Awards Ceremony at CEIViz ’06

APEX, N.C., October 19, 2005 –Dr. John M. Blondin, professor of physics at North Carolina State University, will be the guest speaker at the CEIViz ’06 awards reception. CEIViz ’06 is the first international conference for high-performance visualization. The conference will be held at the Disney Coronado Springs Resort in Orlando, Fla., February 22-23, 2006.
Blondin’s presentation will focus on discovering the complexity of supernovae through 3D simulation. Modern astronomical observations are revealing a universe of stellar objects that are dramatically asymmetric and time-dependent. One example that has been observed is a core-collapse supernovae, where the death of a massive star generates a blast wave so strong that it spreads throughout the surrounding area for several thousand years. Blondin will show examples of how scientific visualization has helped in the discovery of key processes that initiate and shape supernova explosions.
“Although current supercomputing platforms make 3D simulations of these events almost routine, the rapid advancement of scientific discovery demands an efficient, interactive way of dealing with the terabytes of data generated in these simulations,” says Blondin.

CEI uses commodity clusters at Lawrence Livermore National Lab (LLNL) to shatter world graphics rendering record Me

APEX, N.C., August 24, 2005 – CEI, a leading provider of engineering and scientific graphics software, shattered the previous record for graphics rendering speed during tests last week at the Department of Energy’s Lawrence Livermore National Laboratory (LLNL). CEI engineers and Dale Southard of LLNL conducted the tests on a Linux visualization cluster used to support National Nuclear Security Administration (NNSA) missions.
CEI’s parallel rendering compositor achieved a speed of 3.17 billion polygons per second using 76 standard dual-processor PCs running on a high-performance networking system. The scene used for testing contained 684 million triangles and ran at a rate of 4.6 frames per second.
The results of the LLNL tests more than double the 1.5 billion polygons per second speed reported this past March in tests by another DOE laboratory on a 128-node Linux cluster. Those tests used a 473-million triangle model that ran at a rate of 3.2 frames per second.
CEI’s record results have major implications for engineers and scientists who increasingly desire to visualize computational problems that require very high-fidelity data, such as hydrodynamics, large-scale structural analysis, and airflow testing using finely detailed automotive and aerospace models.
“We’ve demonstrated technology that enables commercial software to run on clusters of inexpensive, commodity visualization hardware, interactively handling visualization problems so large that they could not be efficiently processed with traditional supercomputers,” says Randall Frank, senior developer for CEI. “This is important due to the rapid increase in the size of simulation models, coupled with the need for interactivity.”
CEI’s high-efficiency parallel compositor is an enhancement to the company’s SoS (server of server) capability that is already in use worldwide to visualize some of the world’s largest simulation problems. The compositor will be a part of CEI’s new DR (distributed rendering) technology that will be incorporated this fall into the company’s EnSight, EnLiten and EnVideo visualization products.

CEI aids shuttle’s return to flight

APEX, July 12, 2005 – When the shuttle makes its long-awaited return to flight, one company in the Triangle area will have more than a fleeting interest.
CEI, based in Apex, has a connection with the return-to-flight mission that goes back to the Columbia Accident Investigation Board (CAIB) study, where the company’s EnSight visualization software was used to corroborate evidence and formulate conclusions about the disaster. EnSight visualizations created by Boeing and distributed to CAIB members using CEI’s EnLiten 3D geometry viewer provided a clearer understanding of problems and potential solutions.
After the Columbia investigation had pinpointed sources of shuttle problems, CEI’s software was used by NASA Johnson Space Center to provide insight into complex flow physics for Discovery’s redesigned external fuel tank (ET). EnSight was also used to help engineers interpret flight and wind-tunnel data, and to design tests with smaller scale models.
At NASA’s Marshall Space Flight Center in Huntsville, Ala., CEI’s EnSight has been used to assess wind speeds and directions to determine their effect on the shuttle, the solid rocket boosters (SRBs), and the ET.
“We are proud that our products and engineers have made significant contributions to NASA’s shuttle mission,” says Kent Misegades, CEI. “We hope that this is just the first step in getting manned space exploration back on the fast track.”

Fluent User of the Year Award winners visualize CFD results with CEI’s EnSight

APEX, N.C., March 31, 2005 – Three of five winners of Fluent, Inc.’s recently announced CFD User of the Year Awards used CEI’s EnSight software to visualize their results. A panel of CFD experts selected five winners from more than 100 papers and studies published in 2004 by users of Fluent’s CFD software.
Dr. John Hart with the University of Sheffield won Most Innovative Use of CFD Technology for an analysis of Great Britain’s Olympic cyclists. Hart scanned the cyclists and their equipment in road-race and time-trial positions and created 3D computer models from each scan.
The models were analyzed with Fluent’s software and visualized in EnSight to predict aerodynamic performance and develop custom drag improvements for each cyclist. The British Olympic Cycling Team won several medals at the 2004 Summer Olympics in Athens.
Dr. Tamer Hassan and a team of researchers from several Japanese universities and hospitals received the Most Impact of CFD on Society honors for research on intracranial surgery. The team combined CFD analysis with MRI scan data to create a patient-specific software modeling tool for neurosurgeons to use in planning treatment and follow-up procedures.
Grids of the blood vessels were created from the 3D scan data and imported into Fluent software. The CFD data of predicted blood flow within the brain for patients with ruptured aneurysms was visualized in EnSight.
Most Impact of CFD on a Business Process was awarded to Dr. Matt Hyre, associate professor at the Virginia Military Institute. Hyre examined glass bottle manufacturing procedures to identify the step in the process that was causing defects. He simulated several alternate design options, using Fluent’s CFD software to predict thermal flow around the bottles and their impact stress regions.
The results were visualized in EnSight, and the stress predictions were used to redesign the thickness distribution of the molten glass for increased bottle strength and decreased defects. Hyre’s suggestion for a new mold was retrofit to the current manufacturing machine. It saved the manufacturer weeks of downtime by not having to test several molds on the line, resulting in a savings of hundreds of thousands of dollars.

CEI helps Los Alamos National Labs win Defense Program Award of Excellence

APEX, N.C., February 12, 2004 -Visualization scientists at Los Alamos National Laboratory (LANL) have worked with CEI, maker of EnSight visualization software, to earn a Defense Program Award of Excellence from the National Nuclear Security Administration (NNSA).
The award recognizes LANL’s advanced visualization capabilities within the new Metropolis Center for Modeling and Simulation. The center supports more than 300 physicists, computer scientists and engineers. Completed in 2001, the visualization facilities allow scientists to see and understand the results of the large data sets they produce – often hundreds of millions of cells in size.
The center includes stereo graphics displays on scientists’ desktops; a visualization theater with a 31-million- pixel, large-screen, stereo PowerWall display system; and three team-oriented collaborative environments with smaller-scale stereo PowerWalls. A CAVE immersive environment is also under construction. All of these systems use CEI’s EnSight Gold for advanced visualization.
LANL and CEI have developed special features in EnSight Gold software to visualize large-scale computational results in VR environments. The software’s remote parallel visualization capability has been especially valuable in LANL’s work.
“The scientists find the remote visualization capability to be essential for analyzing terascale problems,” says Robert Tomlinson, ASC VIEWS program manager at the Metropolis Center. “They can keep massive amounts of data on the supercomputer where it was generated – whether offsite or in our machine room – and run a client on a local visualization computer here in the Metropolis Center. This makes the visualization of terascale data sets routine.”
LANL visualization scientists currently run EnSight Gold on large SGI visualization computers with 16 graphics pipes. CEI and LANL are partnering to develop the ability to visualize ever-growing datasets on both next-generation SGI shared-memory visualization systems and distributed-memory PC cluster visualization systems.
“The award confirms that CEI provides critical technology to LANL’s Metropolis Center scientists,” says Kent Misegades, CEI president. “We have proven that as a commercial supplier we can deliver a superior product that meets specifications, maintains competitive pricing, and is delivered on time.

Japan Atomic Energy Research Institute Licenses EnSight Gold to Study Alternative Power Source

Japan Atomic Energy Research Institute Licenses EnSight Gold to Study Alternative Power Source
APEX, N.C., June 8, 2001 – The Japan Atomic Energy Research Institute (JAERI) has purchased eight licenses of CEI’s EnSight Gold software to help in its research to develop a cheaper, pollution-free energy source.
JAERI scientists are using the software to visualize calculations from simulation testing for its tokamak thermonuclear fusion reactor, which they hope will someday become a new power source to replace fossil and nuclear fuel reactors.
Tokamak projects are being conducted all over the world in a quest to find an alternative power source. A tokamak reactor, named after a Russian word for its doughnut shape, generates electricity through thermonuclear fusion. It is the same process that powers the sun and stars. Extreme heat (100-million degrees Celsius or more) at extreme pressures of intense gravitational fields drives hydrogen nuclei together until they fuse, forming helium and releasing energy.
“With energy shortages and rising oil prices in the U.S. and other parts of the world, this type of research has begun to intensify and will become more important to our world energy needs,” says Kent Misegades, CEI President. “EnSight Gold is designed specifically to visualize these kinds of advanced, high-end scientific calculations. It provides parallel processing, multi-pipe graphics, flow-feature extraction, VR support and other features that allow scientists to make sense of huge problems that can contain billions of nodes.”
JAERI, established in 1956 for comprehensive research on nuclear energy, has been involved in tokamak since 1961, with a goal of demonstrating a fully operational thermonuclear power plant by the year 2050.
Since 1999, CEI’s product line has grown from one package to six integrated offerings, including EnSight, EnSight Gold, EnVideo Basic, EnVideo Pro, EnLiten Basic and EnLiten Pro. CEI now offers an entire suite of tools for visualization needs, from plotting to the most advanced VR displays.
CEI has corporate headquarters in Apex, N.C., and authorized distributors around the world. In addition to
EnSight and related products, CEI provides consulting services to engineers and scientists from organizations that need to visualize computational results for research, product design or product refinement.

University of Colorado Licenses EnSight To Visualize Nano-Scale MEMS Simulations

APEX, N.C., November 30, 2001 – The University of Colorado at Boulder has licensed CEI’s EnSight software to visualize the nano-scale deformation and failure points of materials used in multi-layer micro-electrical- mechanical systems (MEMS). Faculty in the Department of Mechanical Engineering are developing atomic simulations to help them understand and quantify exactly how small the next generation of components can be while remaining structurally stable.
Assistant Professor Ken Gall and Associate Professor Martin Dunn have received funding from the National Science Foundation and Sandia National Laboratories to examine aluminum-silicon and gold-silicon material systems for MEMS. The professors and Jiankuai Diao, a doctoral candidate, will use EnSight to visualize simulations of the MEMS, which will be subjected to a wide variety of external factors. These factors, such as temperature change and applied velocities, simulate the loading condition of the actual MEMS. The simulations will permit researchers to alter the structure of the materials until an optimal material is found.
The technical challenge is quantifying the material deformations, which occur on a microscopic level. “The simulations involve large amounts of data and have previously been hindered by lack of computing speed,” says Gall. “To model the deformation of a 0.1-micron cube, for example, the attractive-repulsive force and energy interactions must be calculated between nearly 15 million atoms. EnSight allows us to visualize and make sense of these high-end calculations.”

CEI Wins $1.4-Million ASCI Contract to Apply Beowulf Cluster for Advanced Visualization

CEI Wins $1.4-Million ASCI Contract
to Apply Beowulf Cluster for Advanced Visualization
Results of research will be applicable to
aerospace, automotive, chemical, scientific markets
MORRISVILLE, N.C., September 29, 2000 – Computational Engineering International (CEI) has won a three- year, $1.4-million contract to research the use of a Beowulf computer cluster to visualize large-scale models for the Department of Energy’s Accelerated Strategic Computing Initiative (ASCI).
The new contract follows an earlier $1.8-million ASCI contract for advanced visualization on SMP (shared memory parallel) systems. Both projects center around CEI’s EnSight Gold, a high-performance, multi- platform visualization and data analysis tool already used in the three primary ASCI labs: Los Alamos, Sandia and Lawrence Livermore National Laboratories.
The Beowulf computer cluster is named after the sixth-century hero who freed the Danes of Heorot by destroying the oppressive monster Grendel. In the updated version, CEI will modify its EnSight Gold software to enable parallel processing on a cluster of low-cost PCs connected by high-speed communications hardware. The goal is to free ASCI scientists from some of the oppression of supercomputing, including high hardware costs and lack of processing flexibility. CEI will use Red Hat Linux software as the open-source operating system, and an MPI processing library to allow the systems to communicate in parallel.
“This project will help advance state-of-the-art, large-scale visualization,” says Kent Misegades, CEI president. “In particular, it enables us to adapt our technology to advanced parallel computing architectures, which we believe will be the systems of choice in the future for scientists and engineers.”
ASCI was formed to develop the high-resolution, 3D physics modeling needed to evaluate the aging nuclear stockpile and accurately predict how time will affect different components. Two fundamental areas of research will be conducted under the new contract:
Extending the scalability of EnSight Gold to efficiently extract results from tera-scale datasets and render the resulting complex scenes.
Increasing EnSight Gold functionality to meet the evolving requirements of ASCI scientists, including display of results in virtual reality environments.
The contract does not involve intellectual property rights, allowing CEI’s work to be incorporated into future products for more mainstream applications in automotive, aerospace, chemical, general engineering, scientific research and other areas.
CEI has corporate headquarters in Morrisville, N.C., and authorized distributors around the world. In addition to its EnSight, EnSight Gold, EnLiten and EnVideo products, CEI provides consulting services to engineers and scientists from organizations that need to visualize computational results for research, product design or product refinement.

Contract work will center around CEI’s EnSight Gold, a high-performance, multi-platform visualization and data analysis tool already used in the ASCI program by Los Alamos, Sandia and Lawrence Livermore National Laboratories. Four fundamental areas of research will be conducted within the EnSight Gold framework:
Extending scalability to efficiently extract
results from datasets of a terabyte or larger
and rendering the resulting complex scenes.
Increasing functionality to meet the evolving
requirements of ASCI scientists.
Investigating alternative modes of user interaction with visual data, including support for partially and fully immersive virtual reality (VR) environments.
Exploring user-interface enhancements specific to the weapons science community.
“We are exploring problems that are several orders of magnitude beyond what is being done today and what will be needed in the near future,” says Kent Misegades, CEI president. “The contract recognizes EnSight Gold as a legitimate framework for the most advanced visualization work being done in the world.”
The contract does not involve intellectual property rights, allowing CEI’s work to be incorporated into future products for more mainstream applications in automotive, aerospace, chemical, general engineering, scientific research and other areas. “The bulk of our work should be applicable to a broad range of customers,” says Misegades.

EnSight Takes First, Second and Third in The America's Cup

EnSight Takes First, Second and Third in The America’s Cup
Sailing is no longer just about wind, water and the skill of the crew. To stay afloat today in a challenging race like the America’s Cup, the competition begins long before the boat even touches the water. Design teams used EnSight for three of this year’s America’s Cup contenders: Team New Zealand, Italy’s Team Prada, and the U.S. boat AmericaOne.
Eleven boats from seven countries competed in the
America’s Cup qualifying event, the Louis Vuitton Cup Challenger Races. Team Prada’s Luna Rossa defeated AmericaOne in a series of races that began in October 1999 in Auckland, New Zealand.
The America’s Cup began February 19, 2000 in Auckland with defender Team New Zealand and challenger Team Prada racing in a best-of-nine series, with the first yacht to score five points being declared the winner. Team New Zealand defeated Team Prada 5-0 to successfully defend its waters. This marked the first time that an Italian boat has raced in The America’s Cup. It was also the first time that an American boat was not in the race as either defender or challenger.

CEI's EnSight Software Visualizes Model Containing More than One-Billion Cells

MORRISVILLE, N.C., February 15, 1999 — Computational Engineering International’s (CEI) EnSight software recently achieved a major milestone by creating an image for a computational test model containing more than one-billion cells. The visualization was created for a technology demonstration at Los Alamos National Laboratory.
“As far as we know, this is the first time a model of this size has been visualized by a commercial product,” says Dr. Anders Grimsrud, CEI’s vice president of product development. “Others have said they reached this level, but we have the images to prove it.”
EnSight is being used by Los Alamos, Sandia and Lawrence Livermore national laboratories as a primary visualization tool for the Accelerated Strategic Computing Initiative (ASCI), a government-sponsored program for simulated nuclear testing. While CEI’s visualization model was a test case, its size and structure are representative of models that will be used in future ASCI computations. Typical models for the ASCI project are currently as large as hundreds of millions of elements, and over the next couple of years they will grow to more than tens of billions of elements.
The model was visualized using eight concurrent servers running on four 128-processor SMPs. It took about half an hour to generate the resulting image. Approximately 60-70 percent of that time was spent doing I/O. The visualization was made possible through EnSight’s parallel processing of data loading and its ability to compute plane clips and isosurfaces. In addition to generating the one-billion-cell model during the demonstration, EnSight showed powerful interactive capabilities. Multiple Silicon Graphics IR graphics pipelines were used to enable real-time interaction with large-scale geometric models consisting of more than 10-million polygons.
“This model is especially significant for the ASCI project, which is just beginning to compute problems of this size,” says Mike Krogh, senior developer at CEI. “It won’t be long, however, before they do this on a regular basis and we are confident that EnSight is ready for the challenge.”
