Hardware techman wrote in with this 64-bit computing news:

Penguin Computing today launched significant new 64-bit software and hardware platforms at LinuxWorld Expo (Booth #865). These new 64-bit platforms dramatically enhance the processing power available to enterprise customers requiring highly robust and scalable cluster and server platforms based on Linux.

  • Scyld, a subsidiary of Penguin Computing, announced the first 64-bit implementation of the Scyld Beowulf cluster operating system. 64-bit versions of Scyld Beowulf will be available for the AMD Opteron and Intel Itanium 2 platforms.
  • Penguin Computing announced that it will begin shipping Intel Itanium 2-based systems for the cluster and high-performance server market in Q2 2004.
  • Penguin Computing announced that it is now shipping 5 AMD Opteron-based servers for the cluster and high-performance server market, and one Opteron-based workstation.

Scyld Beowulf combined with either Itanium or Opteron systems from Penguin Computing will provide cluster customers with the advanced processing power and memory addressing advantages of 64-bit hardware platforms.

All of the announced products are being demonstrated at LinuxWorld Expo. For detailed product information please see the individual product press releases also issued today.

"These new 64-bit product announcements from Scyld and Penguin Computing demonstrate our commitment to bring innovative high-performance computing solutions to our enterprise customers," said Enrico Pesatori, president and CEO of Penguin Computing. "These new platforms continue Penguin Computing’s strong leadership position in scalable Linux-based enterprise computing platforms."

A Visit Inside CD adapco Group Germany
Posted Fri January 16, 2004 @04:26PM

News On November 13, I was able to visit the offices of CD adapco Group in Nuremburg, Germany. My visit was hosted by Dr. Milovan Peric, Director of CFD Product Development. Dr. Peric is a well known expert on CFD and co-author of one the most widely-referenced books in the field of CFD 'Computational Methods for Fluid Mechanics'.

Dr. Peric joined CD adapco Group in October of 2001 and since then has headed development of a new class of solvers based on computational continuum mechanics (CCM). What this means is that the solver is very general in nature and is not restricted to solving only the Navier Stokes equations. Sometimes this is referred to as "multi-physics".

The general nature of the solver allows different analysis methods to exist within the flow solver such as the capability to solve certain types of solid mechanics problems along with the fluid solution. Using such a tool it is possible compute deformations and stresses in the solid part simultaneously, without the need to couple an FE-solver for the latter part of the analysis.

News IES have now released our new Windows-based CFD code, MicroFlo, as an integral part of the system, a CFD code designed specifically for building applications. Users don't have to be CFD experts because the building model automatically supplies all the data required. Excellent graphics make the results easy to understand, and enable users to communicate effectively with their clients. So now, when users need to produce a detailed comfort prediction for different areas of a room, find out if displacement ventilation works, or see if a building funnels the wind, MicroFlo provides the answers - quickly and easily.

The is a unique software system of integrated building performance tools operating from a single model, it brings together all the design strands you need into one unified system. From the earliest stage of the design process you can assess not only CFD but also, solar impact and right to light, capital and running costs, natural ventilation, thermal performance, occupant comfort, daylighting, occupant safety and evacuation, carbon emissions and building regulation compliance.

NASA Educational Software Helps Students Learn About Aeronautics

News A new educational software product designed by the educational technology team at NASA Ames Research Center, Moffett Field, Calif., has been licensed to MakerToys Inc., Silver Creek, N.Y., and soon will be commercially available for individual use by students in grades 5 through 8.

"'Exploring Aeronautics' was done in cartoon animation to make it appealing to kids," said Andrew Doser of NASA Ames, a graphic artist who helped produce the CD-ROM. "It was developed by a team of multimedia programmers, artists and educators, in conjunction with numerous NASA Ames scientists, to introduce future generations of engineers to the fundamentals of flight, different aircraft and how they fly."

Originally developed as teacher-paced software, the 'Exploring Aeronautics' CD-ROM is an excellent learning tool in a classroom setting and has been very popular with teachers. MakerToys has added a "Teaching Leader" to the CD-ROM as a tool to guide students through the wealth of information on the CD-ROM.

Events: NAFEMS and ERCOFTAC Announce Joint CFD Seminar
Posted Mon January 12, 2004 @11:40AM
Print version Email story Tweet story
News NAFEMS and ERCOFTAC, two of the leading independent organisations with a keen interest in Computational Fluid Dynamics, are working together to arrange a seminar on the subject of “Quality and Reliability of CFD Simulations”.

Computational Fluid Dynamics simulations are being used increasingly widely in industry and academia. More and more results of these simulations are relied upon to provide understanding and often both quantitative and qualitative data that is used to design, certify and understand flow systems. The complexity of the system simulated can mean that direct validation with test data is not always trivial, so it is important for the analyst to understand the level of confidence they can place on the result of the CFD simulations.

This seminar tackles the issues faced when trying to ensure CFD simulations are of a good quality and when determining the extent to which their results can be relied upon. It will be held in the offices of Sun Microsystems in Coventry, UK on 9th March 2004.

For further details, please contact Anne Creechan on 01355 225688, or visit the seminar website.

Application: Optimization of a Multistage Axial Gas Turbine with DOE Methodology
Posted Mon January 12, 2004 @11:04AM
Print version Email story Tweet story
Application Leonid Moroz and Yuri Govorushenko of SoftInWay, Inc. have posted a white paper describing the optimization of a multistage axial gas turbine using design of experiments methodology.
A key turbine design problem is turbine optimization for "as designed" and "off-design" regimes of operation. This issue can be effectively addressed with problem-oriented design-of-experiment (DoE) methodology.

Work was carried out with AxSTREAM™ software that has integrated DoE functionality. Implemented in the software a system of filters automatically suggest a set of project parameters from those that are relevant to a selected turbine design task. It makes a program very convenient to use and significantly speeds an optimization process.

The goal of the work was to demonstrate how DoE methodology facilitates optimization of the multistage axial gas turbine flow path using meanline approximation.
