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

[mumus]

Oh yeah, I forgot to add prime.h to the commit. It's fixed now. It was a problem with commit b6a92cd8b9.

Works now, thanks. Any plans to include xpm protocol functionality into the wallet so we can use it as a hub ? Having to download the entire blockchain on every node is a pain ... plus it would allow us to experiment with current pool miners, jhprimeminer, xolominer, etc..

No plans for that currently. I've been hoping that the stand-alone miner devs would eventually implement either getwork or getblocktemplate (GBT). GBT is working and getwork should be fixed but I haven't tried it. There's a few forks of jhPrimeminer out there that do that but it looks like the code hasn't spread to the more popular forks. Also, I don't know the specs of the pool protocols so I don't know exactly what the advantages are.

I have spoken to both Aerocloud and clintar. Offered a .5 btc bounty for implementing solo mining capabilities. They refused. I think they both have a deal with the pool owners preventing them from releasing solo miners. If anyone reading this knows xpt protocol and can implement it into the original wallet let us know, i am sure more people will chime in to increase the bounty.

It's not clear to me what is your goal after all. Do you want XPT protocol implemented to the wallet to mine with it on yPool (and some other pools that supports xpt) or you want a good standalone miner (like Aero's)that works also in solo mode using getwork or getblocktemplate protocol? Implementing the later one is not a big deal for me. Basically I have these protocols already implemented in https://github.com/hg5fm/jhPrimeminer (like mikaelh mentioned above)

My goal is to make available to the primecoin community a standalone, open-source miner that can be used for both pool and solo mining. Pool miner devs are more active than mikaelh, they tweak and release new optimizations/settings more often, it would be better if xpt protocol is implemented into the original wallet.

I've had it with binary only (jhprimer solominers) builds infected with rogue wallets.

Hello,

I would like to ask for reasonability of Primecoin solo mining on setup 16x Intel Xeon E5-2620 @2Ghz (I'm running on Primecoin-HP). 

Thank You very much

Hello,

I would like to ask for reasonability of Primecoin solo mining on setup 16x Intel Xeon E5-2620 @2Ghz (I'm running on Primecoin-HP). 

Thank You very much

1. Run the latest HP client on one of the machines, ensure all CPU threads are used.
2. Go to debug console, type: "getmininginfo"
3. Use this magic:

Here's an updated formula for calculating blocks/day:

blocks/day = chains/day * (0.97 * (1 - fracDiff) + 0.03)

Here fracDiff is the fractional part of the difficulty, i.e. fracDiff = diff - floor(diff).

This is simply assuming that it's a 0.03 probability for the (k+1)'th number being prime in a chain. These result in longer chains which are not subject to the fractional difficulty. This number was produced by the function EstimateNormalPrimeProbability() in my latest code. It's a bit smaller than my previous estimate of 0.035 being the probability.

4. Multiply by 16
5. Look up exchange rate of XPM on any of the sites which list it. http://www.cryptocoincharts.info/#jump-xpm-btc
6. Calculate your obtainable $/day
7. Calculate your costs: electricity - you'll need a wattmeter of some kind.
8. You can now answer your question.

Hi primecoin
I didnt forget about you!

hi, is it possible to run miner on SPARC?

[cloh76]

I just started mining Primecoin, although I dont understand much about it compared to mining other coins.  Im using an I7-3770.  Are the results below good?

I have a 2nd rig which is the same config but does on average 2250 primes/s.

What is the best miner and config/bat to use so i can get the most out of my setup?   Im only using 7 of 8 threads. (genproclimit=7)

hi, is it possible to run miner on SPARC?

I have only tested my code on x86 and x86-64, so some issues will likely arise on other platforms. You would probably need to do some porting to get the code running on SPARC.

Hi!

I can't sync my wallet

I've already add these nodes:

-addnode=137.116.230.21 -addnode=94.23.215.174 -addnode=87.98.146.72

Still nothing and still no connections to primecoin network

Also on pool mining, I have awfull performance... I'm using a double xeon X5690 2x6cores 2x12threads  with 48GB of RAM and my val/h are about 1val/h...
Also on a double Xeon E5540 2x4 cores I'm having about 0.35val/h...
On my Intel X3960 6c12t about... 0.3val/h
And Finnaly on a 4770k I have 0.4val/h...

What is going on? Can I have a problem with my network connection or something? I'm using Windows 8 on all the PC's.

Thanks for the help

André

[cloh76]

when you say val/hr is that the same as XPM/hr?  If so, my efficiency sucks too.   I have 2 machines with 3770K prc's and im averaging .050 XPM/hr

I compiled and ran this on ARM back in the day (mined two blocks on a Linkstation, FWIW). The main thing to worry about *coin daemons on fringe platforms is endianness, as some of the protocols are stuck on little-endian. I never got a wallet working on a PowerPC but my custom mining script was fine :-j

(Rant: hash algorithms, network byte order, and natural number systems are all big endian. The original Bitcoin client/daemon was developed on x86 Windows and it makes all kinds of assumptions and translations with byte order. Banks will never use *coin because big iron is traditionally big endian )

Is primecoin on a deathbed ? Abandoned by the developers, undervalued, and soon to be replaced by a real prime-generating algorithm - RieCoin ??

What do you mean by "real prime-generating algorithm"? I don't think Riecoin is better than XPM in any way -- not more scientifically valuable, difficult to mine, and the developer seems to have already been MIA. Some coin holders are pumping it, and that is about it.

Worst part about Riecoin is that its difficulty algo is from the stone age, compared to XPM. I don't see why anyone would consider it to be better.

But I'd really like to see another version of the Primecoin HP client at some point. I doubt it's already so perfect that there's nothing to improve anymore.

Using a closed-source precompiled miner? U mad?
