Thats all very well and good....but what do they then use such a creation for?

WHAT DOES IT MEAN?! :p

OUR MISSION

Lawrence Livermore National Laboratory has a mission of strengthening the United States’ security through development and application of world-class science and technology to:

Enhance the nation’s defense;
Reduce the global threat from terrorism and weapons of mass destruction;
And respond with vision, quality, integrity and technical excellence to scientific issues of national importance.

If you are interested in this sort of thing http://www.top500.org/ is the source for the current latest and greatest machines. But the most interesting thing here for me are the power requirements, which are pretty impressive compared to other supercomputers in the list as the cost of running these things is astronomical at best.

Also with regards to GPU supercomputers, there are some in the list, but programming with CUDA / OpenCL is a nightmare compared to working with MPI on the CPU based systems.

the same as it does everyone elses pc...

computing power doesnt = better graphics they can only ever be as good as they were made to be....

super computers generally dont have graphics cards anyway?

Probably around the same Ghz you would get in a regular machine tbh. it won't be more than 4Ghz, due to the heat 1500 cpu's would put out.

As for ram, well, quite a lot more i would think. I'd say in the Terabytes area tbh, heck could be more :p

It's based on the BlueGene architecture so it's massively parallel POWER7 CPUs, that makes puts it between 3.5GHz and 4.5GHz depending on the exact CPUs they've used. Memory is 1.6PB spread across 1.6 million cores (up to 8 cores per physical processor) so it's not likely to be paging!

I've just been reading this article from the BBC and am struggling to get my head around the above quoted paragraph. I imagine they've used that comparison to provoke that very sense of 'woah!' but I wonder how the supercomputer would compare to, say, a mid-range home PC? Regardless, those are some pretty bonkers stats.

Imagine what Skyrim would look like on it :o

Ipad2 was as fast as a Cray 2.

I have already listed those specs, 18/16 core 1.6Ghz.

You can't compare it clock for clock, so it isn't really 'the same as a regular machine'.
