Terminated.
After your Primecoins mature, feel free to PM me with offers. Will pay for in BTC.  Nothing ridiculous though.  I'm not paying 0.01 BTC per XPM.  Looking for bulk purchase. 
It will be certainly more worth than 0.01btc.

Why not use "native" flag?
Umm i have no clue tbh, compiler noob here. Prior to optimizing i just cloned in the git and let the makefile do it's job and got 120 - 150, now 170-200pps atm. Try the native flag and tell us if it further improves things, I'm happy for now.  Grin

edit: Ofcourse it still dips down to ~140 sometimes, very variable "primerate".

lol... people, don't sell your precious primecoins for pocket money.  Tongue
QMAKE_CXXFLAGS += -O3 -march=core-avx-i
QMAKE_CFLAGS += -O3 -march=core-avx-i
Very good clue. Gained ~33% by doing this (using primecoind on linux though, just changed the xCXXFLAGS to -O3 -march=corei7 etc in the makefile). Before my i7 930 peaked around 150, highest so far is 200 (7 cores).  Grin
Look for your cpu type to put after march here: http://gcc.gnu.org/onlinedocs/gcc/i386-and-x86_002d64-Options.html

Buying PrimeCoin, PM me with your offers.

Wait, aren't you the one that called primecoin "another thread cluttering coin" at the beginning of this thread?

Yup. He is. Everybody get your pitchforks out!!

Very good clue. Gained ~33%, maybe less since it's difficult to compare, by doing this (using primecoind on linux though, just changed the xCXXFLAGS to -O3 -march=corei7 etc in the makefile). Before my i7 930 peaked around 150, highest so far is 200 (7 cores).  Grin

Who knows, what was start prime number on XPM? 1 or biggest available ATM?

Gentoo ebuild of the daemon here, for the true believers. Modified from bitcoind 0.8.2 ebuild.

https://github.com/teknohog/ebuilds/tree/master/net-p2p/primecoind

Any guide on how to use it?

You use Gentoo and you need to ask? Perhaps start with these (the first two I googled)

http://linuxreviews.org/gentoo/ebuilds/
https://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=3&chap=5

I'll put up one Bitcoin in bounty for a CPU-miner (standalone) that will run on both windows and linux and outperform the built-in miner.
Recompile the existing one with some more optimization flags or with the ICC compiler. Tongue

Hence the ebuild Cheesy

(I do have a standalone build script for a few coins, but I've had issues with it recently, and the ebuild way was easier to fix.)

"There are a few who seek primes just for the money. There are prizes for the first prover ten-million digit prime ($100000), the first hundred-million digit prime ($150000), and the first billion digit prime ($250000)."


primecoin is not designed to find the largest prime (millions of digits long).  It will not attempt to look for the ones listed in that competition.

If it was possible computationally to achieve this with Primecoin, why not? A small donation to the humble miner(s) helping to find the block...


primes at that size are too computationally intensive.  Remember, every other node on the network needs to validate the work, so it becomes prohibitive to look for very large primes.   The "value" of this program is to look for chains of primes at smaller values.   I'm not sure if it will have any real value though since they will be a random smattering of chains...  Specifically Cunningham chains which have already been described by mathematicians.  What's the value in finding more of them?   It's sort of like finding your second starfish on the beach.

Sunny King you brilliant bastard!

If he were brilliant he would integrate GIMPS in it to get the possiblity to achieve some of these prices

ten-million digit prime ($100000) was achieved 2009

The primes we calculate will never reach the ones proven by GIMPS

to prove that 2^57,885,161-1 is prime it took 88 hours with a GTX Titan, 200 hours with a 3570k

is anyone working on a mining pool?
almost 24 hours and nada on my i7 920, yet some shmuck's mined 3 blocks on his crap laptop? ><

I started mining last night on 2 of my 4 physical cores, and have gotten 40xpm so far from two blocks. I've gotten a few other people on board as well IRL. I really like the fact that this cryptocurrency provides public proof of work, and the PoW is useful data.

5 pcs - ~130 for the rate, 24 hours of mining...
40 XPM... too bad, is this luck or what  Huh

Every block reward is placed into a new address IIUC.

What port is primecoin running on?  I need to verify that some active ports I've discovered are just the primecoin running...

I've seen Protocol.h file in Src folder and found this info:

Code:
#define PRIMECOIN_PORT   9911
#define RPC_PORT         9912

I have a question. If a block is found, which address are the coins deposited in? Is it just the first address in the book?
