Games "It all began when a young man named George Hotz began to work on the PlayStation 3, trying to gain access to the machine in a way that made Sony uncomfortable. In response, Sony removed the OtherOS functionality of the PlayStation 3 in a mandatory update, and the hacking community was not happy with this decision, resulting in a sort of cold war. PS3 hackers have once again gained the upper hand: Linux has been returned to the PlayStation 3."

Nowadays the cell is easily beaten by a modest GPU using CUDA, STREAM or OpenCL.

If you read the given links, you'll see what the US Air Force has done.


Easily beaten by a modest GPU

So we have to choose between those two possibilities:
- The US Air Force is not well informed.
- An internet commenter is not well informed.

That is actually a false dichotomy, and both of the elements in the dichotomy are fallacies themselves.

A fallacy inside of a fallacy, inception!

Or... such purchasing decisions were made years ago when the Playstation still had the lead.

Anyway, the Playstation Cell processor achieves 230 GFLOPS single precision. An entry-level nVidia GPU such as the Geforce GT 440 (~80 Euros) achieves 342 GFLOPS single precision. More expensive cards and Tesla stream do above 1 TFlop. Also, modern GPUs have a lot more memory available, which is nice, because it allows for larger working sets and copying data from main memory to the GPU memory is expensive..

Also take into account that generally everyone agrees that CUDA is much more fun to program than for Cell, and that modern off-the-shelf Intel CPUs have 2-4 cores (compared to PS3's single core PowerPC CPU), x86 hardware is suddenly far more interesting these days than the Playstation 3.

But after all, we are comparing 2006 hardware to 2011 hardware.

The military does not move at the speed of light. It is at the best interest of a company to sell any branch of the military a stock of systems and shoehorn them into support contracts. I have under good authority that the Army Corps of Engineers still has DEC/Compaq/HP Alpha systems clustered running VMS.
