Hardware An anonymous reader wrote in:

The architecture of Red Storm, the new Opteron based supercomputer developed by Sandia National Labs have emerged on the web.

The 77 page presentation [pdf] gives the complete specs of the Red Storm Architecture, designed to be a single system with a fully connected 3D mesh interconnect.

The Red Storm uses 108 cabinets and 10,368 Opteron 2GHz processors, and around 10TB of 333MHz PC2700 DDR memory.

The monster uses Linux on service and IO nodes, LWK (Catamount) on compute nodes, and a version of stripped down Linux on the RAS nodes. The whole beastie takes less than 2MW of total power and cooling.

According to the presentation, system software performance scales "nearly perfectly" with the number of processors to the full size of the computer (page 15) and provides a scaling analysis on the following page.

There's some interesting discussion on Amdahl's Law, and we suggest if you're interested you go over here, and check it out for yourself.

Application: A Landmark in Simulation

Application by Nick Waterson,
Mott Macdonald, UK

Mott Macdonald is an international engineering and management consultancy based in the United Kingdom and operating world wide in the fields of construction, transportation, energy, water resources, the environment and education.

The Simulation Group within Mott Macdonald has been using CFX-4 and CFX-5 from ANSYS CFX for more than 12 years to solve a wide variety of problems relating principally to fire safety, wind engineering and power generation.

The Maitreya Project International is planning to build one of the largest statues of the Buddha in the world. The statue, with a height of 152m and a design life of 1000 years, is to be located in northern India. Mott Macdonald has been acting as consultant for a number of aspects of the design as well as the project management. The unusual nature and size of the structure mean that a number of advanced analysis techniques, including computational fluid dynamics, are required to overcome the many design challenges. During the preliminary design phase, one key issue to be addressed was the effect of extreme wind loads on the structure. It was decided to use a CFD approach for the initial determination of these loads, to be backed up by wind-tunnel testing and further CFD studies later in the project.

Application: Coupled CFD and Thermal Analysis of a Steam Turbine

Application A SoftInWay application story details the steady state coupled fluid and solid thermal analysis of a steam turbine secondary flow path.

Prediction of steam turbine rotor and stator thermal state is a complex problem that usually is divided into a set of interdependent problems related to steam flow, heat transfer and thermo-mechanical modeling. Some of most important modeling issues can be identified as follows:

  • Turbine flow path heat transfer boundary conditions;
  • Heat transfer boundary conditions related to the secondary part;
  • Secondary steam flow including the flow in disk/diaphragm cavities and seals;
  • Windage losses;
  • Turbine rotor and stator thermal steady analysis;
  • Seals radial/axial clearance optimization.
The predicted thermal state shows a significant influence of secondary steam bleed flow on the temperature distribution of the rotor and stator.
