[XPM] [ANN] Primecoin Release - First Scientific Computing Cryptocurrency

[Vannicke]

I agree that PPS seems to be untranslatable.   An intel system with 5000 PPS I had produced one block in all of it's four days running, while another AMD system which also said 5000 PPS but finds a block every 6 hours or so, though it is now dry for 14 hours. Edit: found one right after posting this.

I think it is statistically unlikely that the one system ran the same as the other, yet in four days one found a single block and the other found twenty-two.  Both systems were started within minutes of each other, and updated to the latest mikaelh release immediately, with same sievesizes on hp3 and hp4.

Well if the factor of thirty per integer of difficulty is true, then our chances at difficulty nine as compared to our chances at difficulty seven should be about the same kind of difference as our chance of solo CPU mining a Litecoin block at difficulty 1 compared to our chance of solo CPU mining a Litecoin block at difficulty 900.

Sure we have improved our code some, but on the other hand CPUs have probably improved since Litecoin was difficulty 1.

So if when primecoin was launched you were finding blocks about as often with your CPUs as you found Litecoin blocks with the CPUs available back when litecoin was difficulty 1, maybe your chances of finding one when we hit 9 might be slightly better than your chances of solo CPU mining a litecoin block when Litecoin hits difficulty 900.

I suggest slightly better because maybe the improvements in the code might be quite significant. Heck maybe so significant that your chances will actually be closer to the chance you had of CPU mining a Litecoin block back when Litecoin was only at difficulty 90 ... Uh, how much chance was that, actually? Hmm...

Think time to turn off the machines. Running dry for over 4 days. Always keep thinking may be I will get lucky soon; but it seems its over now as we come close to 9 difficulty.

how many pps are you pulling?   what build wallet are you using?

'Mining' at 5,000 primes/sec, any calculators to estimate average time to find a block?

Someone gave a very very rough estimate of 1 block/24h @ 5kPPS.

That's my experience also.

Over a 10 day period ... I was at 2 block/day @ 3kPPS, now at 1.5 after 1 block in 2.5 days.

.. I'm buying up anything under 0.003.  Anyone stupid enough to sell to me for under that, I'm a happy to take them from you.

Lot of coins available at 0.003 (mcxnow), how much you are going to purchase?

Well now, he implied that he'll buy all available under that price point.

Therefore, happily, if his money is where his mouth is, there is a solid price floor we don't have to worry about falling through.

And, IIRC, someone else also made pretty much the same statement of "I'll buy everything at or below 0.003.". But I'm not gonna bother going back through the thread to find it.

Now here is someone establishing a true price floor.
10,000,000.0000    0.00000003    0.3000     

With the price now 400% up on the time that I wrote that I would buy anything under .003, and that you were all stupid for selling them at that price, I thought it would be a good time to re-quote this post   I didn't buy much at that price (a few BTC), and what I did buy I ended up selling off at .01 for a happy 3-4x profit.  I'll be keeping what I have mined for a little longer.  Thank you

Nice I bought some at $0.32 and sold for $0.56 but kept the profit in coins which are now worth double I'm gona keep them till I see 0.05 or never might use them hopefully.

If I have a core i5-2500k - that is four cores, what should I be putting my setgenerate to? I have set it everywhere from -1 to 16 and I am currently at 1250 primespersec. Is primespersec the best way to determine effectiveness?

-1 uses all available cores

setgenerate true 3 for 3 cores
setgenerate true 2 for 2 cores etc

setting it to -1 will utilize all cores so will give you maximum performance.  1250 is probably all you're going to get out of an i5-2500 and it may take several days to find a block at that rate.

what if they hit 0.1? they will if no gpu miner apear or big bug in prime codes...

-1 uses all available cores

setgenerate true 3 for 3 cores
setgenerate true 2 for 2 cores etc

Setting it to -1 gives only 240 pps.

It may use all the cores but not enough threads or something.

[Grumlin]

it's imposible. Somebody generate block very fast. For one day was generated about 3000 blocks... it's unreal

There are probably some miners who have GPUs working they just haven't told anyone else how to do it.

It's .0122! You lost money.

try setgenerate true 4 and see what happens

-1 and 4 are not good settings - I'm leaving it at 24. I guess that means 6 threads per core.

Geez, primecoin already broke through $1.25 and now hovering at $1.05 at current prices.

At least it isn't NVC.

Primecoin is doing the litecoin!

As a tribute to food like BBQ, we should create a PrimeRibCoin.

Is a normal mined block 12 XPM?
