I think AMD really dropped the ball with this one. They have great GPU products, but they let NVIDIA's CUDA take foot hold while largely depending on OpenCL. It will take some time before OpenCL catches up to CUDA; there are a number of compilers that have CUDA optimizations (e.g. Portland). With that said, the one thing that GPUs are still lacking is error checking in their memmory. There are many HPC applications that require this. I look forward to the day that ECC comes to GPUs. My 2.5 cents.

[citation][nom]sunflier[/nom]"having 7,168 GPUs"Are those in one giant daisy-chained SLI mode??[/citation]

Most (but not all) of the supercomputers on the "Top 500" are a bunch of regular computers with low latency interconnects (like Infiniband). So there might be 1792 nodes with four GPU each, not sure if that's what is actually the case here but you get the idea.

[citation][nom]scrumworks[/nom]Mmm, actually HD5870 beats GTX480 in Crysis which is kind of hilarious.[/citation]
Which drivers, running which version of Crysis? At least in Crysis Warhead, I can't recall the HD5870 outperforming the GTX480 since the initial release drivers. At gamer quality, enthusiast shaders, and 4x AA, the GTX480 consistently outperforms the HD5870 at all tested resolutions, and in terms of minimum frame rates (extremely important in any fps) the gap widens significantly.

...so I'm not sure what performance figures you're referring to. It's probably a good idea to cite a source, or at least double check the benchmarks, before making a claim about supposed performance.

It's the original Crysis where 5870 outperforms the 480.

I believe Fermi based Tesla and Quadro GPU's do enable ECC memory.

Like PCs ECC memory is usually for servers or very high end systems, and following that pattern Tesla GPUs (what these HPCs use) do have ECC memory.

if nvidia can pull that off with a relatively low power consumption, I'd like to see what ATI could do (assuming they ever provide proper support for super-computing).

Okay, I see. I just haven't seen a review site include a benchmark for the original version of Crysis for a while now. Care to update me?
