[XPM] [ANN] Primecoin High Performance | HP14 released!

[truckythin]

which are the best pool to min XPM now guys?

[muto]

ypool is by far the best, since it is the only one

Well ... if you have a fast CPU ypool is actually not the best ...
My 8 core Opteron finds a block every two to three days (~20->30 XPM), where as on ypool I only got 4 to 5 XPM in the same period.
Started solo and getting way more XPM's

edit: I take my offer back...

Am interesting in binary for centos 5.6 however.

[bcp19]

its all about luck my celeron found 2 block in 2 days, i5 none

I highly agree.  Since switching to -hp10 I've found 9 blocks between 5 computers... both Core2Quads and both i5's have found at least 1... my i7 has struck out.

I fully agree, that mining solo is better if you can stand the variance. Bu he asked for the best pool, not for the best way of mining.

true ... 
so go for ypool please ... better chance for me in finding blocks!
Thank you!

HP10 definitely more faster than HP9, I think the diff will going to 10 very soon.
I also selling my AWS $100 Credit for BTC LTC XPM, PM me with your offer.

I kind of doubt that.  It looks like Diff actually fell a tiny tiny little bit recently.  And it's near the end of the month, with a GPU miner looming around the corner.  I think we'll see a lot of monthly payment VPS miners getting off the train in the next day or two.  Much too risky to invest in another month of payments.  I bet we won't see diff 10 until GPU miner comes out.

Oh yeah? it also probably true

I would think that almost all VPS providers would be billing each month on that users sign up date, not the start of every month. So we'd be seeing changes continuously throughout the month if this was the case. But in fact we see diff is still rising each day, if only slightly.

I refuse to change my mining operation or mining plan on the whim of the possibility of a chance that there might be a GPU miner coming out. I will believe it when I see it.

FYI primecoin.org home page now has a link to the hp client download. Hope the miner icon I add is likeable

I think this helps new users to find it easier. Once again let's give Mikael a big round of applause for his hard work, dedication and selfless contribution!

Great idea! Thanks Sunny! And thanks to Mikael, of course.

Awesome.  Many thanks to you both.

Nice truck icon 

[Trillium]

Sunny I like the simplicity of the home page. It does not spam you with endless info like some other cryptocoin sites and looks very clean. And yes the truck icon is amusing!

I like it!

Any reason to not only use the hp client? Even if not mining?

Looking at the code, unless there is a bug in the algorithm that is say rejecting 10.5 length chains at the moment, it *should* behave linearly. Diff 9.999 should be same as 10, but but from the charts it is obviously not.

I think the distribution of the Fermat's remainder is skewed. Sunny mentioned that briefly in his paper too. The skewed distribution is probably caused by the repeated exponentiation done during the Fermat's test.

I wonder if this is because all the current miners are optimized to sieve for 9 chains at the moment? I wonder if the the difficulty would look more linear if miners switch to sieving for 10 chains now that most 9 chains won't solve a block. I would love for a -sievelength param to be added to the build that would sieve for chains of a set length. I would do it myself and experiment but I am having some difficulty building the project on windows, and I suspect it is at least as hard as bitcoin to build.

I can build the ypool miner easily and from those experiments the sieve length is quite effective at optimizing for chains of a desired length.

I'm a bit doubtful that switching the target difficulty to 10 would be beneficial at this point. It might become beneficial when difficulty is around 9.9 but I haven't really investigated that.

Also it's good to remember that optimal mining parameters are probably not the same for ypool and solo mining. Ypool miners are concerned with maximizing the value of their shares. Previously that system was exploited using shorter chains. Now that the system was changed radically it could be possible to exploit it with longer chains.

The building procedure for the stock Primecoin client should be the same as for Bitcoin. For my version you also need libgmp on top of that.

Ah ok, if the distribution is heavily skewed, and the number of miners was increasing rapidly, that could explain some of it. Well, if the parameter is added I would try it out now even if it is too early and see what happens.

I did eventually get it to build on mingw64 with the gmp 5.1.0 source. For fun I collected stats on the decimal part of the distribution of all 5+ chains, separated into 1% bins. It looks fairly flat:

Code:

66 54 53 55 52 56 44 70 68 53 53 57 54 33 53 46 61 68 66 67 55 69 59 58 39 60 73 58 51 61 56 56 53 56 66 50 72 76 58 57 55 55 61 55 62 67 53 58 46 44 59 60 53 62 39 46 47 55 55 48 69 77 47 56 75 52 65 74 41 49 67 53 74 47 49 63 55 57 47 61 59 63 45 59 54 55 61 62 48 61 55 62 63 55 70 62 50 81 55 64

Would I be correct in saying the chance to find a prime in a set that is sieved is about 0.095 and the chance of finding a prime just randomly is  1/ ln(2^255) = 0.00568 ?
