I just made the post out of interest as to what could be done with these GPU's

Kotuku
Hi Kotuko, thanx for putting the posting about the supercomputer it is fascinating, they are saying it is giving the processing power of more than a 500 PC cluster, I only mentioned the aspect of how it would work when playing COD4 in that with Flight Simulator FSX I know plenty of people who have paid money for a second or more cards to run under SLI, and FSX does not support SLI so it does not run any faster..........

Best and Warm Regards

Thanx for that Everlong, SLI for the amount of time it has been around has sure got problems in that even if a Game supports SLI and many do not, unless one has seen a test by a reputable organization of a particular card combination with a particular game, one never knows what the result will be of using a particular SLI card / Game combination.

I am happy with my single 9800GX2 <smile>
99. % sure it is not a spoof, a university would have access to code writers perhaps even people who could code in low level machine languages and no doubt they have written a special software that might even by pass the whole commercial gaming SLI thing entirely for their activity. In theory, using Graphics processors as they have done, might have huge advantages to gamers, in that it would make computers hugely more flexible if the Graphics processors could be used for non Graphics general purpose computing. The problem is that they are using the Graphics processor to translate data in to images, so they are still using a Graphics processor in a traditional way and if one tried to use this technique in gaming for the general purpose aspect of the game, one would run in to the problem of how to go about allocating individual aspects of the overall computational task to each of the many sub-processors within each of the eight 9800 multiprocessor units within the four 9800GX2s and the problem that many of the individually allocated tasks would be interdependent on one another, yet running on different sub-processors. E.G. most software today can not effectively use 2 cores in the likes of AMD Athlon 64 and Intell Conroe, so there is little chance of being able to use hundreds of sub-processors in a multi-graphicards rig for that purpose. Since what they appear to be doing, is rendering images in a non-real time environment and this is one of the relatively few tasks that lend itself easily to multiprocessor use, I can not think it will provide any advantage to gamers in respect of the general computing tasks associated with games, though major organizations using these cards as a replacement for PC clusters might well bring about a massive increase in the capability of these cards, not in SLI but as single cards for gaming.
