Not sure if this has been asked, but any way to get the prime numbers out of the client or a way to grep them from the logs? .. also is their a way to reference them to already existing found ones more in the math community side of things?

primechain and primeorigin are in the getblock output.

Refer to this thread for existing world records of these chains:

Hey guys, I am getting ~300 pps and been mining for hours. Still no XPMs. Is this normal? (and yes I've read the threads!)

Did anyone noticed that the primecoin-gt.exe v.0.1.1 has a timestamp of 01/29/2011?

Wow just installed this one and it found a block within the first 5 minutes!

I'd like to know this also. I know they know what primes are being produced because there is some news on new chains being found, but where is that info?

Its the first coin that could have people using NVidia cards instead.

Anyone working on a GPU miner yet? Here's some help: http://www.macs-site.net/CudaPrimes.htm

Hopefully not, because:
1) Primecoin looks to be GPU-resistant, it will be very hard to implement calculating it's long integers on something that is design to deal only with vertices
2) GPU rigs are the cancer for mining, eliminating 99% of regular people who are not OK with the idea of monster cases with external GPUs all over the place, laptop users with no external cards, etc. Non-existence of GPU miner is the main reason for Primecoin's unusual popularity. People are successfully mining even on Raspberry Pi's.

Without GPU's, the only people who will make any money will be the people with botnets or EC2 instances.

Yea GPUs are good for primes
check it http://www.primegrid.com/

open cl and cuda apps

If anyone's interested, I just made a bash script to run from an Ubuntu Server instance that does all the work for you in setting up a CPU miner.... I know it's just a couple commands but some people seem to be getting hung up on that!

https://github.com/lucasjkr/PrimeMiner/

It's a cludge, I know - no error checking or anything else, but it's a very simple process:

A) Start a new instance and install Ubuntu Server 12 or 13 on it.
B) install git "sudo apt-get install git-core"
C) get the script "git clone https://github.com/lucasjkr/PrimeMiner.git"
D) make script executable "chmod 700 ./PrimeMiner/makeminer.sh"
E) execute script "./PrimeMiner/makeminer.sh"

Enter your admin password, sit back and wait.

PS - i know entering the password is bad form, but for myself, i'm only running these on instances that do nothing else, so I'm not concerned if some how someone was able to capture the password. Your mileage may vary. But I'm happy with this so far. Suggestions will be of course appreciated!

It can be done on GPUs. Look up CUDA Lucas. Its used for finding mersenne primes. Verifies primes over 10 million digits long in days.

How to set genproclimit (cpu) to maximum capacity?

You don't set a genproclimit and it uses full cpu capacity. You only set it if you want to throttle it.

So how can I throttle it?

'setgenerate true '

Either 'setgenerate true' or 'setgenerate true -1' will cause it to use all capacity.

Just installed the 0.1.1 client released not even an hour ago for windows. Was the 1st downloader of it on sourceforge. I'm getting 3 PPS. This is a i7 3940xm cpu. What's wrong?

just for reference: I have an i7-3720QM (mobile CPU, @2,6 GHz) and get close to 1000 PPS with Sunny King's latest Windows release (0.1.1). I don't know about architectural differences between your CPU and mine, but its at least the same family...

Looks like you can't set a genproclimit. I tried to do half cpu while working on the computer. I took the limit off and now its 780 using the full CPU.

Now get high 800s pps. 880 at 100% vs 3 at 50% - looks like a bug.

The problem is that it just keeps happening, and unless I constantly stare at that numbers I just end up wasting several hours of mining every time it does it. Is there seriously no way to fix this?

Get the new official client here: http://sourceforge.net/projects/primecoin/files/

how do you know if you are on the wrong block chain, also witch files do you delete to re-download the blockchain.

If you find your "current number of blocks" stay the same for a long time, then you are in trouble. To be sure, you may check http://www2.crypto-expert.com/primecoin/index.php to see what is the correct number right now.

Just restart the software and it will automatically reconnect to the network and update the block chain(most probably the correct one...).
