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.

Huh. If this chart is correct, me and a friend are collectively mining 10% of all blocks in the past 24 hours. Kind of cool to be a big fish for once.

Sunny and Mikael are going to be seeing a huge donation from me if this goes well. Smiley
You're claiming you found 400 blocks in the last 24 hours?
Each of us has collected over 2k XPM in the past day. 200 blocks*

Just out of curiosity: How much pps are you fielding for that?

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

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.

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.

I posted a new compilation guide for Linux:
https://bitcointalk.org/index.php?topic=259022.0

It shows you how to compile your own libgmp and everything else.
