Is there a built in core limit for a single miner in the code?

Any Pools?

GPU mining is absolutely pointless. A public GPU miner will only drive up difficulty, and we'll be right back at ground zero again. Pointless.
Anyways, I have now mined 140 XPM! (ON a single computer) Seems I'm quite lucky.

There are two reasons why I ask ... one is "selfish" : I have 3 strong GPUs while only 1 mediocre quad CPU. ... the other is, I think it's better to have GPU mining in place IMO is more resistant to botnet-mining. Or am I mistaken to believe this?

This can't be a serious contender in the coin game without a guaranteed ROI for miners.
This needs a mining pool, or people are going to get disillusioned, fast.

Guaranteed ROI?
*facepalm*
Point me in the direction of a coin that guarantees ROI.

I'm mining with some cores, CPUs are burning

Nobody? I see in this entire thread others had this problem too. It MUST be more than one, it's 15 cores running...
Give it a few minutes and the rate will show...
-tb-
Edit: nevermind. just noticed it has been more than a few minutes for you.
I have this problem too. There is something broken in the linux client. It mines at 0 pps on all my gentoo computers, but Ubuntu and windows work. I mined from the beginning and the only computer I can get going is my crappy windows box.

The interesting role GPU miners will play in this coin is that, since PrimeCoin (like PPCoin) reward varies inversely with difficulty (higher difficulty = lower reward per block), original zero-day cpu miners will get a bit of a boost when GPUs come in and make the block reward fairly low.

Correct me if I am wrong but isn't there already an existing set of prime numbers that are known?
Would this not be applicable to the proof of work function here?

There are infinitely many primes. However, the table of known primes is rather big and increasing all the time. New primes are huge and it takes weeks/months of computing power to find them, so I don't think this project can actually find any new ones.
So in a way, I believe you could use the list of known primes, but then it becomes a memory-bound problem, and it's probably faster to use other tests than search through the list.
you could not use any list. It's the same thing with SHA/scrypt mining: you could have a table with the nonce for every possible midstate. However it's not possible to store such table. If you could store one bit of information on every particle of the universe (imagine the whole universe is your hard disk), then you would need many universes to store that data.
With prime numbers it's even worst: SHA/scrypt possibilities are huge but finite. Prime numbers and Cunningham chains are infinite. Genesis block has a starting prime in the order of hundreds of bits. If all his primes are this size then it's safe from tables.

I agree. I always wanted to see a CPU-only (no GPU mining ever) coin..Anyways, I have now mined 140 XPM! (ON a single computer) Seems I'm quite lucky.
I was hoping for YAC to be CPU-only, but then GPU miners started popping and

I was wondering if the prime95 client can be used for pool mining

Can someone with more software/hardware knowledge explain me what will it take to develop a GPU miner for this, and how long should we expect to wait for something like that? Is it harder to do than it was with YAC?

Well I've been mining for all of 30 mins my laptop i5 giving 35 primes at 50% but my ltc mining rig AMD cpu at 75% only 10 primes.
Let's see what happens by morning.

I got 1 in the first hour using a core2 duo and not a single one after that till now.... Added 2 more core2 duos! No luck .

how many confirms to mature?
Generated a block on one of my 7 boxes last night... just wondering when it's spendable!

For anyone interested, digitalOcean's $0.007 (7/10ths of a cent) per hour server slice gets around 15-22 PPS. However, their 8-core $0.23 gets around 2.

Seriously this i7 machine has been running 100% on 8 cores for over 14 hours and not one reward?
If we can't join a mining pool and at least get rewarded for the amount of work we put in, whats the point? we are just gambling with our time. This can't be a serious contender in the coin game without a guaranteed ROI for miners.

I mined for 2-3 hours at the initial release with no blocks found. Decided to turn it back on while I slept. 6 hours later, I woke up to find I had discovered 2 blocks. Not too shabby I guess. I might continue to do this, but it's too damn hot to leave it running during the daytime.
