Topic: [XPM] [ANN] Primecoin High Performance | HP14 released! - page 69. (Read 397616 times)

Is this only a problem in hp7? If it is, I assume that most folks would be better off by going back to hp6.

ah - thanks for your answer  . 20% seems about right to me from the blocks I solved with v7 vs v5. I had about half my instances on v5 and half on v7.

edit: NVM I understand the debug file and why it fluctuates. the stats are calculated based on last 60 seconds of mining, then multiplied by 60 to get per hour.

No, it won't show up in primes/sec or chains/min. I'm guessing it's reducing block rate by about 20%.

thanks for all the work mikaelh, I will send some XPC tomorrow because I've been using your miner. I compiled with your latest updates and will see how many blocks I solved in a while...

I do not understand primecoin that well at the moment, the problem with v7 would that be reflected in primemeter stats in the debug file, does anyone know?

BTW the measurements on the primemeter lines are about the same I think  for compiled with recent commits from bitbucket vs v7. . the numbers are "per hour" but fluctuate a lot which doesn't make sense really.

Can you post more information about your system and the which exact versions you are comparing?

I am currently testing the latest commits, it seems that the PPS indicator is very low compared to the value before, more than halved my numbers and chainspermin is 0 mostly all the time.
I will keep on testing, meanwhile, is anybody else testing the CURRENT version and seeing the same results out there ?

Well, technically my Windows builds have been using static linking. It can be changed to dynamic linking. x86 will take a minor performance hit from that but x64 should be fine.

Even if the licensing concerns are solved through dynamic linking, it's still Sunny King's call whether he wants the code or not.

@mikaelh: Why not merge your code with Sunny King's? He stated that it's due to licensing problems with libgmp (can't find the source), but I think that this is wrong. libgmp is LGPL, not GPL, and can therefore be used even in closed-source projects provided that you link to it only dynamically. Which primecoind does, so you would be fine even if primecoin would be closed-source.

That indeed explains a lot !
96 hours without a block...

I'm thinking about all those that are paying a fortune for vps and were mining at difficulty = 10

yes

Does this mean that people with hp7 that find blocks are effectively at difficulty 10?

That would certainly explain my long dryspell...

Good catch! Letting that one slip was definitely a big oversight on my part. I pushed my own fix to bitbucket just now. I don't have time to do a release right now so it'll have to wait for a bit. In the meantime the fix is up there for testing.

I'm sure it took some hard work to be the first pool.

mtrlt replied that this commit is not what he was referring to, and the commit is after the hp7 tag which mtrlt pulled into his project.

I believe he is referring to the code below - which appears around lines 556 & 606:

This code returns false without first calculating the fractional part, exactly as mtrlt explained. I'm testing a fix and will let mikaelh know if it works.

Looks odd to me

Is this the specific change that causes the bug you are referring to: https://bitbucket.org/mikaelh/primecoin-hp/commits/64528eba386c948e4e63d50b9eb6c1a500bac4ca ?

Here's the original comment explaining why it should work: https://bitcointalksearch.org/topic/m.2787426

What are your thoughts?

Only one pool exists for now: http://ypool.net/

Is anyone just running hp7 at default?

What, if any, are the preferred changes for i72600 and AMD FX830?

I don't know how that can affect your wallet  . I'm using different wallets in each miner and dump the private keys every time a block it's found, then I restore the keys on my "money PC" where I only run the official client. After that I stop primecoind on the miner, delete the wallet and restart the client.
