aws cc2.8xlarge,
primecoin-0.1.1-hp5 two changes:
1) prime.cpp
const unsigned int nPrimes = (uint64)nTotalPrimes * 8 / 100; // down from 10
2) main.cpp
static const unsigned int nPrimorialHashFactor = 9; // up from 7
You seem to be testing two changes at the same time. The first change will definitely affect performance while the second change shouldn't as people have already pointed out. It's likely you're only seeing the effects of the first change you did. mikael, knowing your work I'll take your word for it, do you agree that 1) is a change for the better and will not negatively effect block finding? |

Sorry i am new to all this ...
But there is one thing i dont get.
I tryed to run it with a primecoin.conf file and changed parameters like rpcuser ... rpcpassword ... gen=0 gen=1 and also with rpcport=9910 rpcallowip=127.0.0.1 with server=1 and daemon=1.
I did not receive any block in earlier stages ... difficulty was past 8 to this stage ...
as i deleted the conf file and run the wallet without it i received two blocks in two hours ...
How can that be ... Luck ? I was using hp3 ...
So my question is is the conf file needed or not ??
Thx

It's likely you're only seeing the effects of the first change you did. mikael, knowing your work I'll take your word for it, do you agree that 1) is a change for the better and will not negatively effect block finding? The first parameter he changed definitely has a huge impact on performance, that's for sure. The parameter is based on sieve round limit implemented by Sunny King. As you probably know, that resulted in a pretty big performance boost. I'm using a static percentage value in my code instead of counting microseconds. Changing that percentage may indeed improve performance on some system. It depends on the efficiency difference between the sieve and the primality tester. I may change the percentage into a configuration parameter in the future. |

2 dedicated rigs mining with 1500pps each since 9days.
One got 9 blocks last block 3 days ago.
other got 0 blocks.
random is random.

running i5 at 2000pps. got about 5% more pps from hp4 to hp 5. Only found 2 blocks since release of first client. got them in the first few days, havent had one since on solo. ypool sucks had a second pc pool mining with ypool way too many server rejected shares.

Sounds like coincidence. But why did you have both gen=0 and gen=1 in there? |

Nah, tryed it once with gen=0 and then another time with gen=1 but i never maintained to get a block...
That is why i am asking if the conf file is important for the mining, if yes how must it be configured then....
thx

Does anyone have a guide for building on Windows. I can't get the static libraries to bind using MingW.

Mikaelh. I have a question for you. My CPU's have 12MB of cache each. Is that advantageous for primecoin mining? I have noticed I have been getting significantly higher primespersec than most of my friends when we use larger seivesizes, even when they have newer processors! |

I have noticed I have been getting significantly higher primespersec than most of my friends when we use larger seivesizes, even when they have newer processors! Well, it might run a tiny bit faster if you have a large L3 cache. I wrote most of the code to run fast using the L1 and L2 caches, so the L3 cache is actually not that important. But of course it never hurts to have a big L3 cache.  GPU architecture also has a big impact. |
