What does it mean when it says "8 active connections to primecoin network"?  Does it mean the amount of cores on the CPU or something else?
That's how many nodes you're connected to.

This is the testnet checkpoint. There seems a bug somewhere allowing you to enter this state. Did you use the testnet at some point and what's the sequence of operations/events related to using testnet? Are you running a testnet node right now with main net node?

You know what, yeah I think I know how it happened, I'm messing around with the client to build a p2p pool, and I'm using the testnet flags and variables to let it know if its running as a pool node or a regular node.

However it still shouldn't have entered this state even though you operated testnet mode.

I deleted the blockchain folders and redownloaded it. And the issue went away so the issue was probably related to identifying the blocks.

I'm not even sure how to test if it was my modifications or not that caused it.

Derp?

Please run these command
getcheckpoint
getblockhash 14131

And post output
Current checkpoint is still on genesis. So I don't expect this to pop up.

Now we wait until someone makes a Primecoin clone called ULTRA-VALUE-GEM-BAR-DIAMOND-PLATINUM-GOLD-SUPER-FUCKTASTIC-Coin with twice the block reward and a 100,000 premine.
But in the case of Primecoin's PoW, everybody is a winner when people clone it.

Not really, GPU miners are on the way(not by me, but I am sure they are).
No they are not.

So much ignorance and delusion in this thread.
Why do you believe GPU miners aren't on the way?

Both sieving and primality testing can be ported to the GPU.

It is a race to the bottom, but once the difficulty reaches a certain point it's change is going to plateau. And the reward will remain relatively constant.

Just a reminder, DigitalOcean 16-core instances get around 2500-2600 primes per sec, and cost $0.72 per hour.
So that's why I'm no longer getting any blocks :s
169  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [XPM] [ANN] Primecoin Release - First Scientific Computing Cryptocurrency on: July 11, 2013, 02:05:25 PM
I haven't gotten any blocks in a couple of days.

I'm starting to get a little cheesed off.  Where the heck is the dev on this one?  Any chance of getting an optimized client so (regular) people can actually use this?

+1

It wasn't that hard to optimize it by hand.

Give C++ a try. It'll do you a lot more good than just making a quick speculative buck in the long run.
172  Bitcoin / Mining software (miners) / How do I tag the coinbase transaction? on: July 10, 2013, 09:13:06 PM
I'm looking at the thing that creates the coinbase transaction, and I'm not quite sure how to insert arbitrary data like ASICMiner does to tag their blocks.

Could somebody offer their insight?

Well it seems the little guys are out now.  The big machines are up and running with the fixed code Sad.  

BTW seems like we have a 10 second gap between blocks now  Cry.
My proposed p2pool client can't operate when the network speed is the same as the p2p chain speed is supposed to be.

I just had a transaction confirmed in under a minute.

The effective mining rate of the network is waaaaay faster than it should be.

any indication of value per coin yet?

About 91033 primes.

Found a CUDA implementation of the sieve here, too: http://www.mersenneforum.org/showthread.php?t=11900

Oh snap, things be going crazy.
Too bad the sieve is only half the problem.

If you can implement the primality tests, then we're talking.

@tacotime

Any hints you want to share? Smiley


Compile with gcc 4.6.x+ x64 and these compilation flags:
Code:
-O3 -march=corei7-avx -mtune=corei7-avx
-O3 -march=native is enough/better.
-Ofast for the person who likes to live on the wild side with imprecise math.
is there a way to optimize anything through windows?
If you compile it yourself, all those flags can be set. Even if you managed to compile it through MSVC, the flags are probably similar.
