A single GPU supercomputers worth some millions of $ would have more power than the bitcoin network.

The top 500 contains multiple supercomputers which use GPUs.   The #2 supercomputer (which was the #1 not so long ago) gets roughly 30% of its computational power from over 7600 NVidia GPUs.   The reality is just that supercomputer are ill suited for mining.  They are inefficient on a MH/$ and MH/W basis because they tend to have lots of expensive (and power guzzling) stuff which do nothing for Bitcoin Mining.  Components like massive memory banks (as in hundreds of TBs), redundant high speed storage arrays (think thousands of 15K RPM SAS drives and now SSDs), ultra low latency high speed interconnects (20Gbps fiberchannel), node redundancy, etc.

Sure you could use a Supercomputer for bitcoin mining, and you could also use a ferrari for hauling gravel.  Doesn't mean it is a good fit.

first i want to say that i agree with you, and that you are one of my favorite posters...

that said, i LOVE how no matter what the discussion is it comes back to MH/$ and MH/W

the other thing that i think we need to consider here is that there is very little need for the government to do this.. in the grand scheme of things even if they comprehend what bitcoins are.. they are such a low priority threat..

Which is why free energy should be on everyone's mind that's interested in mining efficiency.  If you have to only recoup HW costs than mining becomes profitable much sooner.

Western govts. not worried about BTC right now. They're too busy trying to prop up failing paper currency. I heard they are running out of the special paper they use to print Euros. There is talk in US about negative interest now. That $$ in your account is actually going to be sucked dry as they charge negative interest.

Governments of the world have thousands of these super computers.
China or the USA alone could bring down Bitcoin.

Bitcoin Miners don't even come close to these monsters.

Can someone please answer my big worry, as i'm really thinking of stopping my mining as it seems futile.

I hope someone has a good answer for me.

Sounds like you are just paranoid.  Do you worry about other things in life, as well?

Why on earth would anyone, in any country use super computers for bitcoin LOL!!!

I buy and sell GPUs, most 5850s and 7970s.

I have a couple bare bone mining rigs for sale as well.

What if these governments secretly started a bitcoin investment arm, using supercomputers? However, it is very unlikely at the moment. :-)

It may help to read the previous posts. Again:

Supercomputers are not cost effective hashers. For hashing you need integer processing power. There is no need for all the stuff supercomputers excell:
  • Fast interconnects (Infiniband...)
  • Vast amounts of RAM
  • Fast Floating Point arithmetics
  • Large disk arrays

And why on earth would governments join the mining fray when they can simply tax miners?

Thanks for your explanation. Now I understand my thoughts are simply crazy and unrealistic!
