I'm getting about the same rate but my CPU is way down like less than 20% most of the time. Anyway to allow it to use full CPU. Win 8 by the way.

In the console of the primecoin-qt you can enter
Code:
setgenerate true -1
That allows all cores to be used. Do you have a "primecoin.conf" file on that machine?

I got an exception running it with maybe 12 threads on 4 core i7 2660. Sorry, removed the error message and restarted the primecoin-qt. Will report details if it happens again.

I'm having the same problem on my two computers; It throws random errors and quits every few hours.  I Have to manually start the program again and start mining.

New version is out. It mainly adds a tuning parameter called -sievesize. Use it like this: primecoind -sievesize=2000000

@mikaelh to make sure ... the change of sievesize is not what Sunny was talking about in https://bitcointalk.org/index.php?topic=253662.msg2716964#msg2716964 , right?

I have reduced sievesize from 2.5M to 50000 in several steps and the PSS indeed rises (not linearly). But I hope it's not just an illusion.

Sieve size isn't directly what Sunny was talking about, but it is related. If you lower the amount of work you perform or the shorten the time you spend working on it before giving up, then you will throw away a lot of potential solutions unnecessarily.

Lowering sieve size to 50,000 will raise PPS but it is an illusion.

Optimal sievesize might be 1000000, some people discussed on this topic.

Thanks for the explanation and for making the HP client. It's hard to determine where the illusion starts.. all I see is more PPS with lower sievesize.

mikaelh is awake and coding  Grin
Latest commit: Precompute two's inverses for all base primes. Idea taken from luke-jr

If you're on linux and compiling from the repo:
Remember folks, if you're doing this, keep your primecoind updated:

Code:
cd ~/primecoin
git pull
cd src
make -f makefile.unix USE_UPNP=-
primecoind stop
sudo mv /usr/local/bin/primecoind /usr/local/bin/primecoind.old
sudo mv primecoind /usr/local/bin/primecoind
primecoind --daemon

compiled and running on Ubuntu 13.04 64bit on a Phenom 1090 hexacore, getting around 4500 - 5000 pps (as before).

What should thelatest changements result in?

I wouldn't expect any increase in PPS resulting from this change (remember PPS is not a good performance metric)... The efficiency is in how quickly the sieve is setup, ready to weave then find the prime chains. Within the gensieveroundlimitms parameter (default 1000 milliseconds) primecoind should spend less time setting up the sieve and more time finding the primes before it moves onto the next round.

ok. So it will be very hard to see if there are perfomance inprovements on the real network...

Around 100 hours without a single block this with 20k+ PPS. I try every build. Now with latest - hp3
Please somebody paste your config file, may be there is my mistake.

As I understand it right, adding sievesize=1000000 shouldn't be necessary as 1M is already the default sievesize...

I had 5 blocks yesterday during ~15hrs mining at 4k - 5k pps. Today no blocks have been yet found during more than 3hrs @ 4.5k pps.

On Linux:
Code:
gen=1
rpcuser=primecoinrpcuser
rpcpassword=primecoinrpcpassword

On Win: no config file, starting the mining manually with setgenerate. If you have config file just delete it, maybe there really is something wrong in it, but i doubt it, probably just bad luck.

The config files are pretty hard to mess up, and even without one you can do: "setgenerate true"
and it will be mining with all the defaults.

What we are all seeing is the amount of computation required to generate a prime chain now that the difficulty is 8.8.
