never seen that one D&T.  I'm trying to get 2 5870's to cooperate in windows vista...Bitminter is only recognizing one card, and I tried GUI miner, and it also only recognized 1. they both show up in hardware manager though.

Looks like it is a bug on cgminer 2.2.5 something to do w/ dynamic intensity (which I had on by accident).  Setting static intensity of 9 made the bug go away.

Awesome work sir! Doing a fresh install of Vista and new drivers on my end, see if I cant pull 850 Mhash out of my pair of 5870's

BTW, what do you do with NMCs? Don't see much demand for them.

I sometimes trade NMC for BTC at Vircurex.

I slipped a referral link in there. :-)

Id really like to see a block finding bonus for long blocks,  to lure some big miners and help us out when our luck is turning sour.
Now we are seeing the opposite, we are have having 2 or 3 (really) long blocks, and as a result hash rate goes down, making a bad situation worse.

If we could offer a bounty, we might see the opposite. And since anyone of us could win the bounty, it would hardly cost us anything.

Maybe once the block goes over 90%, the fees go to the solver?

kjakman, our hero!

I just hope we never see a block like one I recall from sometime around October.  I think it was BitMinter's 18th block or somewhere in that range.  It took over 9 days and the CDF was 99.7% or 99.8%, if I recall correctly.  We only had ~30 GH/s at the time, though.

Maybe if Dr. H gets some time he could implement a block hall of fame with the 10 shortest and 10 longest blocks on a CDF basis either just for BTC or BTC and NMC.

Alternatively could show it is shortest/longest block (nominal shares), shortest/longest block (time), shortest/longest block (CDF).

At same time how about "best lucky/unlucky streak" = max # of sequential blocks either all over or all under 50% CDF. Smiley

Question: how come the last 5% of a block takes significantly longer to mine?

I just hope we never see a block like one I recall from sometime around October.  I think it was BitMinter's 18th block or somewhere in that range.  It took over 9 days and the CDF was 99.7% or 99.8%, if I recall correctly.  We only had ~30 GH/s at the time, though.

Question: how come the last 5% of a block takes significantly longer to mine?

Because there is no max.  CDF isn't saying we "mined 95% or x%" of a block it is saying 95% of the time we should have solved the block by here.  Another way to look at it is at 95% CDF only 5% of blocks are longer/worse.  In the long run we expect the average block time to be 50% CDF and roughly half the blocks are shorter and roughly half the blocks are longer.  There is no set min or max though.

You could solve a block in 1 share or you could have a 11 million, or 100 million, or even theoretically quadrillion share block.  The odds start getting very unlikely (like 99.9999% CDF meaning only a 1 in 1 million chance of having worse luck).  Then again people win the lottery.  Lets hope we never run into a 99.99%+ monster.

Wow! Thanks for the explanation, now I'm really scared Smiley

For a more graphical representation of what DnT just said, have a look at this graph at Slush:
http://mining.bitcoin.cz/stats/graphs/
(scroll down to the bottom one)

Its a good illustration, but not to nitpick, but he shouldnt round to 100% as he does when you hover the mouse over the chart, because it never becomes 100%. Just really really close to it Smiley

Theoretically, the entire bitcoin network might not find a block for over 2 weeks; if difficulty wouldnt be adjusted to 1 in such unbelievably unlikely scenario, it might even continue for decades. Actually it might anyway, I dont know what happens to difficulty if no blocks were to be found for 2 weeks.

Hmm would suck if it created some race condition which caused the network to halt. Smiley

Let's all stop mining for 2 weeks and test it. :p

But just think how many you could mine in the 2 weeks after that!
