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

[gudmunsn]

I haven't gotten any blocks in 4 hours. The diff hasn't changed, so I am assuming that people who have optimized their miners are getting the lion's share. I don't know much about miner optimization, but I am going to start poking at the code to see how these optimizations could be made because I suddenly have motivation! LukeJr, do you have any hints for people getting started on where to look or what to look for?  Are you running Linux?

Actually, it seems that the diff increases with every block mined.  If you list you transactions, you will notice that the diff increased between every block you have mined.

Yeah, but it started at 7, and now it's at 7.2, 1.2 days later. However, in my experience, the ability to mine the coin has gone down significantly. I was finding about a block an hour, and now it's been over 4 hours with nothing. I could have been extremely lucky earlier, but I would place my money on the assumption that at least a few people have figured out how to mine this in a more efficient manner.

Does anyone know where in the code (or can translate to layman English) which hardware can actually mine or is restricted from mining?
What I mean is: Some people having issues with EC2 nodes. My old/free CR-48 will not get any primespersec at all. My two desktops work fine. Etc, etc.
Is there some prerequisite to have >0 primespersec within the code that could be referenced so I don't waste time compiling on old hardware only to not have it mine?

[Luke-Jr]

Any hope of a gpu version?

At least with my current (still incomplete) comprehension of the algorithm, it requires a bignum library.
With this in mind, I don't plan to do a GPU port on my spare time.
Maybe later, after CPU is working, if someone is willing to sponsor the development time.

LukeJr, do you have any hints for people getting started on where to look or what to look for?  Are you running Linux?

Well, the most obvious one was hashing the block header once per nonce instead of 1-3x...
I think the rest of my optimizations required actually comprehending the code

Since you can't buy this coin anyone want to buy mining time on servers? I've got around ~40 XPM/day on 8 cores(at 0.01BTC at pop thats 0.4BTC). I'll break even tomorrow. I'm going to run it for about a month so thats like 1200, or 12BTC.

I'd like to launch some more servers so let me know if you are interested while the difficulty is still low.

Going by this rate, this would value Sunny Kings idea at $15,000.

For two days of coins, it's pretty high, no?
Of course I understand it's low for miners who actually would prefer to keep their coins at that price - especially since it required time to understand and set up.

That seems really, really, really low. You've got a very low production rate of XPMs

It's not especially low. It's still at 19 coins per block, from a starting 20.

Remember it's not the coins that matter, it's the idea and the network that has value. The idea of a potentially scientifically valuable output is new, and potentially valuable.

everyone has their own opinion, remember, people out their think coins like bottlecaps and megacoin etc.... are innovative and valuable...

got a block in about 90 seconds after opening the client. thats my luck used up for the year

Well, you might be right.  I have to admit that, right now, I don't really know how much harder a difficulty of 7.2 is than a 7.0.  Difficulty is very different for this coin, I think.

Around how many blocks per day can you get with 15 primespersec?

[RustyShackleford1950]

Could be 0, could be 5, honestly no way of giving you a straight answer. It's not an exact measurement.

Any chance of seeing a wallet for OSX?

I'm almost sure that there is no such thing as hardware black (or white) list. You may be getting 0 primespersec becuase your hard is too slow.

[FiiNALiZE]

Now it's hovering around 45 primespersec.

I guess it was getting warmed up. I have a i7-2600


I'm gonna leave it running overnight with a fan so the temps don't go above 76C.

Hopefully it'll be worth the effort.

I am running mine with less then all cores to keep temps down:  'setgenerate true 3'

OK everybody I find the pattern: whenever I paid attention to how the miners were working they don't find anything. When I went to lunch, dinner, sleep they found coins.  

In concur, this is how it always work.

Unfortunately hardware follows the same pattern for failing...

My rack is running at a warm 80-70 celcius.

[Loktera]

44 blocks until the first block matures!

[hak8or]

Wait what? Has the blockchain been reset? And if so, does that mean that my previous mining proceeds will not be counted?

Do I have to redownload the client now, or restart it, or anything like that? This would explain why my previous two blocks only 3 hours apart were the only ones and for roughly 22 hours I did not get any other blocks.

[ReCat]

blockchain wasnt reset
