AMD Opteron Ideal for Low-Cost CFD
Posted Thu May 01, 2003 @09:39AM
Print version Email story Tweet story
Hardware AMD's newly released Opteron CPU has a number of features which make it an ideal CPU for a low-cost multi-processor CFD compute server. Let's take a look at some of the features most useful for CFD computations.

Support for 32-bit and 64-bit operation

Many people are starting to bump against the memory address limitations of 32-bit computing when running large CFD calculations. Moving to 64-bit computing raises the memory address limit from 2^32 (4 gigabytes) to 2^64 (16 exabytes) although it should be noted that the Opteron uses 40-bit physical memory addressing putting the limit at 1 terabyte of physical memory. (An exabyte is 1,000 petabytes, a petabyte is 1,000 terabytes and a terabyte is 1,000 gigabytes.) Such a change will be essential for running next generation CFD problems utilizing millions of grid points.

But many CFD applications (grid generation, for instance) will be fine running in 32-bit address space for some time to come. This is where the Opteron shines because it can run both 32-bit and 64-bit applications natively, whereas the Intel 64-bit processor (the Itanium) uses an emulation layer to run 32-bit applications. The result is good CPU performance in both modes.

Flat Panel Displays Reviewed
Posted Thu May 01, 2003 @09:30AM
Print version Email story Tweet story
Hardware CADALYST has reviewed 9 flat panel monitors for price and quality. Flat panel monitors offer a number of advantages over the old CRT (cathode ray tube) designs. Image quality is superior on flat panels because the image is produced digitally therefore there are no convergence issues or interference problems from nearby electrical equipment. A second area where flat panels shine is in desktop space savings. Large flat panels are only a couple of inches thick allowing them to be used in confined areas. Also, flat panel monitors are roughly 1/3rd the weight of CRT monitors and only draw about 15% of the power used by CRTs.

So, now that you are ready to upgrade to a flat panel, which is the best for the money? The CADALYST review ran the test monitors through a standard test suite from DisplayMate Technology. The CADALYST review then went on to include a number of qualitative tests such as stand quality and resistance to fingerprints.

In the end, all of the flat panels tested got high marks, but the Dell UltraSharp was chosen as the top monitor.

CFD Applications in the Chemical and Process Industries
Posted Wed April 16, 2003 @01:18PM
Print version Email story Tweet story
CD-adapco From the production of polymers in stirred tank reactors to the making of Italian pasta through the moulder-extruders, "optimisation" is the keyword for the process engineers and plant operators. The question commonly asked by process engineers and plant operators is how to achieve the target product quality consistently in the shortest time and with the minimum energy input. To answer these questions, the engineers need to have a good understanding of the processes in their equipment.

For example, how the fluid is stirred and heated or mixed with other fluids and reacted chemically. These processes are complex and their effects are often inter-linked with each other. For example, the mixing of two fluids leads to a chemical reaction which generates heat and change in fluid viscosity which in turns affects the way of mixing.

In the last decade Computational Fluid Dynamics (CFD) has become a widely used analysis tool by engineers to gain a better understanding of the complex flow processes in their equipment.

The CD adapco Group has published an article which details the ways in which CFD can be used to optimized these processes.
