#2I don't understand these articles that assume you understand what "two 2.40-gigahertz Intel Xeon E5645 6-core... and two NVIDIA M2050/C2050 448-core .... which reside on a Supermicro 2026GT0TRF motherboard" means, but didn't already know what "CPU" and "GPU" stand for.

#3From Feng: “The next frontier is to take high-performance computing, in particular supercomputers such as HokieSpeed, and personalize it for the masses.”
This is one of my favorite things about technology. As few as five years ago I was drooling about an Intel C2D chip and looking forward to quad-core chips. Nowadays that's standard technology in smartphones. I'm amazed by the graphics performance in the new Asus Transformer Prime with the Tegra 3 chip which has up to five cores.
The biggest problem with packing more power into smaller spaces is the battery consumption issue. Maybe there's no silver bullet for that only more efficient software and hardware usage.

#4I am not trying to be difficult but how is a $1.4M anything for the masses? Are they allowing the public to run jobs on the machine? Is there anything new about HS that brings SC500 power closer to my home office?

#5As a Hokie, this is good but SystemX was way more revolutionary. At the time, supercomputers weren't built on consumer hardware and the fact that it was in the top 5 (3?) with a bunch of G5s was like a shockwave. Basically, COTS supercomputers had finally arrived when SystemX came out.

If by 'SC500' you mean a supercomputer that has a high ranking on the Top500 list, it's already here: http://arstechnica.com/business/news/2011/11/amazons-cloud-i...

As another VT alum (two times over, and the second time being last year), I can tell you that what they're probably most interested in is the energy efficiency. Feng's group does research with both GPUs and power efficiency. Wu Feng and Kirk Cameron (also at VT) were the ones who started the Green500 list.

I meant how does the VT system bring SC500 to the masses. As in the "supercomputer for the masses"?

Whilst your average person at home may not be able to fork out $1.4M, this is in the afordable range of many medium to large businesses, and opens up access to private compute clusters*
The highest cost for supercomputers isn't the raw hardware - it's the power consumption. This also includes the cooling needs of a large cluster. Over the lifespan of a cluster, these will add up to a significant multiple of their base cost.
* of course, this may not be the ideal way to provide access to these services

#10A bit of engineer's rough estimating:
System was built in 2003 - 8 years ago. Assume moore's law of doubles every 2 years - expectation of 16x more powerful Actual increase in performance - 22x in 1/4th the size
Given that it's then a quarter of the size of system X, that's an amazing increase in peak performance.
There's only one problem - that speed increase appears to owe a lot to the use of GPGPU. As I understand it, whilst research into GPGPU for HPC* is a hot area at the moment, the scale of the actual benefits it offers is still a matter of debate (especially when considering costs and power consumption).
