But I still can't help to think making the next best super computer isn't a matter of HOW but simply getting the money together to do it. Are the interconnects stretched that thin?
I don't know much about it, just from news articles like this. But the networking definitely seems like a hurdle to overcome, especially with adding more nodes to increase the power (latency probably reduces it I imagine). Also optimization too, spreading out that load so it works efficiently sounds complicated.

It seems like it is based on the RISC arch

According to a quote from HEXUS.net
Quote:
ShenWei chips are said to "bear a strong resemblance to the Digital Alpha chip, but according to Top 500 list co-founder and renowned HPC researcher, Dr. Jack Dongarra, it is not an Alpha variant
Which is based on RISC from what I found.

In the Fluid flow track on the Delft university we usually use approximations and other semi accurate relationships sometimes however you can not get away with this and you actually have to knock on wood. A simulation of some forced turbulent flow around a cylinder took 3 months of crunching on a supercomputer.

Money well spent...

Either give use better super computers or some math guy figure out if we really need to calculate everything that happens before the phenomena we want to study. I doubt if anyone is going to solve it, as it's been many years and even for a million bucks no one was able to solve it. Million bucks is chump change versus the amount of money that could be saved.

It would be interesting if china started using this tech in commercial servers

Id wager loads of money on their MIPS derivative.

I'm saying China (number two in government spending) has the lead in super computers over the U.S. (number one in government spending) probably because the U.S. keeps their spying machines listed as classified.

Basically I'm taking shots at both of them for poor spending habits

Pretty sure military spending of the USA greatly surpass those of supercomputers. So I wouldn't be so worried about the US spending money on supercomputers when the military segment is where all the money is getting dumped at.

Well, DoD has its own super computers paid for by military spending. thumb.gif

Pretty sure Welfare spending of the USA greatly surpasses it's military spending. Makes you wonder what they could do if they got rid of most of that and put it into supercomputer funding. Would be pretty great for those that have need for computing power.
