Thats getmininginfo details.. so this means my qt client is mining primecoin? and if its mining, how long time it will take to find a block on current pps? Thanks. Wink

Prior to this release I was getting about 1400 PPS in the Windows client and about 1800-2000 PPS in my ubuntu VM.

I downloaded this Windows one and get about 5k PPS on 7 cores on my FX-8350 @ 4.7ghz.

I tried the the linux one and I'm only getting ~996 PPS?

I like using the linux one because it always seems to be 10c cooler and prior to this I was getting higher PPS in linux.

Steps I did:

Code:

apt-get install make
apt-get install git
git clone https://github.com/mikaelh2/primecoin
apt-get install libgmp-dev
sudo apt-get update
sudo apt-get install python-software-properties screen python-rrdtool python-pygame python-scipy python-twisted python-twisted-web python-imaging build-essential libglib2.0-dev libglibmm-2.4-dev python-dev autoconf automake ncurses-dev sysstat gcc-mingw32 libmysql++-dev cloog-ppl build-essential automake gcc libevent-dev libmemcached-dev libcurl4-openssl-dev zlib1g-dev libjansson-dev curl memcached libtool unzip freeglut3-dev libxi-dev libxmu-dev build-essential freeglut3-dev libxi-dev libxmu-dev mpich2 libdb-dev libminiupnpc-dev libboost-all-dev libdb++-dev git uthash* libgmp3-dev

cd ~/primecoin/src
make -f makefile.unix
mv primecoind /usr/local/bin

primecoind setgenerate true 7

I'm a linux noob so go easy on me.

I'm a bit confused.

The primes we are finding are huge, what purpose does the up-to-2,000,000 or so prime sieve serve?

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.

Delete your blockchain and redownload after every new compile or downloaded qt. I hadn't had a block in over 48 hours at 4000 PPS. Deleted block chain on all my computers. Voila. 2 blocks last night. I may as well have mined salad because I was on a fork for 2 days.

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.

So you'd suggest -sievesize=1000000 ?

Hey, I built the last client, I'd like to know if I should be seeing a PPS increase with it, or is it just other optimization that make the client more likely to find a block?.

A pool is a must at this difficulty level, IMHO, provided a working standalone miner is released. People would get less frustrated because of their bad luck at solo mining.

There is something strange with this coin/daemon
It is locking sometimes mining nothing and using whole cpu power
To repair it kill daemon do -rescan and start again
You can easily spot this if you have immature coins locked at specific number of confirmations, but daemon block number is increasing

I wasted many cpu power because of that

I ma using hp2 build, ubuntu

Sounds a bit like your client got stuck on the wrong fork. Sunny King's original client also suffers from that issue.

Please somebody paste your config file, may be there is my mistake.

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.

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.

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.

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

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

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://bitcointalksearch.org/topic/m.2716964 , 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.

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.
