I think you missed this part:

The results of his work have just been published in the journal Computational Biology and Chemistry under the title of “Implications of the Turing completeness of reaction-diffusion models, informed by GPGPU simulations on an XBox 360: Cardiac arrhythmias, re-entry and the Halting problemâ€. The good news is that his hunch was right and the XBox 360 GPU can indeed be used by researchers in exactly the money saving way he envisaged. Simon Scarle said: “This is a highly effective way of carrying out high end parallel computing on “domestic†hardware for cardiac simulations. Although major reworking of any previous code framework is required, the Xbox 360 is a very easy platform to develop for and this cost can easily be outweighed by the benefits in gained computational power and speed, as well as the relative ease of visualization of the system.†However his research does have some bad news for a particular set of cardiac researchers in that his study demonstrates that it is impossible to predict the rise of certain dangerous arrhythmias, as he has shown that cardiac cell models are affected by a specific limitation of computational systems known as the Halting problem.

48 x 500MHz x 34,000,000 = 816,000,000,000 floating point operations per second

Developing a GPU client for distribution over Xbox Live would be cheaper and more productive than buying a thousand, 216 core nVidia GPUs.

No. My math is perfectly fine. You're confusing the ability to actually use a CPUs maximum theoretical performance under perfect, single precision conditions.(FLOPS) as apposed to whats realistically available.

You can say the same for any processor...

See: [email protected] on PS3. No doubt using high-end GPUs would be cheaper and more productive if they are making a personal HPC, but this could be something that could take advantage of the 34 million Xbox 360s sold.
