[XPM] [ANN] Primecoin High Performance | HP14 released!

[ReCat]

Same here. Although are you sure that's right? 1 block is worth 5 bucks right now. My rig draws 200~ watts when mining. I estimate that's just a couple of cents in power.

[romerun]

what's up with the git, has the latest code moved somewhere ?

In hp4 I don't have to manually configure he sieve size do I?   It gives an automatic 1 mill correct?   It's just that on page 1 the faq refers to manually entering it...

The default sievesize is 1mill. No need to do anything if you don't wish to change.

Report on sievesize (for 20 systems @ 3000pps each, hp4)
 - 700K: no blocks after 2 hrs
 - 1M: ~1 block/hr
 - 2M: ~0.8 block/hr
 - 4M: ~0.6 block/hr

Seems 1M sievesize is the sweet spot?

Same finding here.

Between 23:30 and 2:30 (1 block/hr)
- I run on 163840 sievesize (weird number, I know, multiples of 4096 - CPU cache size, and I found this to give the best PPS on 1 core and 2 core  machines)

Between 5:00 and 7:00 (1 block/hr)
- I run on 2M sievesize (again seems to decreased to 1 block/hr)

Default - all other times (2 blocks/hr)
- I run on default 1 M




Conclusion: default 1M is optimium for finding XPM blocks!

What's the best OS for this in this list?

ubuntu 12.04.1 server amd64
gentoo amd64 minimal 20121210
ubuntu 12.10 server amd64
gentoo x86 minimal 20121213
CentOS 5.8 x86-64
CentOS 6.3 X86-64
FreeBSD 9.1 release amd64
debian 6.0.6 amd64
debian 6.0.6 i386

It's a VPS, and only has linux options...

ubuntu 12.04.1 server amd64 is a safe bet

Yet I'm having trouble compiling the miner: http://www.ppcointalk.org/index.php?topic=341.msg2361#msg2361
Haven't got an answer yet...seems to be a bug or something when doing apt-get install for certain dev files.

I had this same error, took me a day to figure out after hours and hours of trying different things.

As blastbob pointed out somewhere in here, turns out it's your Memory that's lacking.

Run this command, it should solve the issue:

Code:

sudo dd if=/dev/zero of=/swapfile bs=64M count=16
sudo mkswap /swapfile
sudo swapon /swapfile

[cryptohunter]

can anyone write a proper guide for this on linux, thanks ?


the guide on this page is not working at all

i want to try it out on my server

this part

sudo swapon /swapfile

gives a not allowed message on my server?

It probably means that your VPS provider has disabled it for some reason, especially for Linux if it is based on kernel-level isolation as opposed to a "real" (OS-agnostic) hypervisor.

I would increase (boost) the RAM size to 1 GB to work around the problem while compiling, then set it back to 512 MB.

[cryptohunter]

yeah it's probably been disabled.

Oh well i will try my dedicated server and see what happens.

did anyone try this guide?

apt-get install make
apt-get install git
git clone https://bitbucket.org/pankkake/mikaelh2-primecoin
apt-get install build-essential libssl-dev libboost-all-dev libdb5.3++-dev -y
apt-get install libgmp-dev
cd ~/primecoin/src
make -f makefile.unix USE_UPNP=-
mkdir ~/.primecoin
echo “rpcuser=SomeUser
rpcpassword=SomethingReallyLong
gen=1″ > ~/.primecoin/primecoin.conf
sudo mv -f primecoind /usr/local/bin/.
primecoind –daemon -sievesize=200000
watch ‘primecoind listtransactions & primecoind getmininginfo’

it seems the guy didnt test it out and there are a few mistakes in there that stop it working?  someone told me this mikaelh2  version would work way better but i like a few others could not get that to work at all? 

[jubalix]

hi,

if I mine on linux do I have to pay mining fees's when I send?

also if I send from the QT (non mining) do I have to pay fees of 0.01 to get it processed

what happens if no fees are paid

what happens if no fees are paid

1) only if you configure them
2) only if you configure them
3) in theory the transaction will be slower.  however i didn't even realise that i didnt have any fees configured and my transactions are pretty quick

[OnkelPaul]

Currently Primecoin seems to be set up with no transaction fees.
I don't know whether that will change when the network is swamped with transactions.
I think that since there is no rigid reduction of mining rewards, transaction fees are not needed to keep miners happy as with Bitcoin :-)

[tocket]

I had to pay transactions fees when I transferred some XPM (using primecoind). The first time it was because the coins were too new (0.01 XPM fee) and the second time because the transaction was big (200 XPM, 0.02 XPM fee).

[hasle2]

Can anyone tell me how to read the primemeter lines in debug.log? What do the three values, prime/h, test/h, and 5-chains/h measure and which one is the best performance indicator?

[Vannicke]

Can anyone tell me how to read the primemeter lines in debug.log? What do the three values, prime/h, test/h, and 5-chains/h measure and which one is the best performance indicator?

Mikaelh said that 5-chains/h is the best measure of performance since 5-chains/h is more on par with the 8-chains [soon to be 9-chains] that we are mining to find blocks.

prime/h = 1-chains and he said test/h doesn't give much info at all.

Try this, just wrote the guide:

[dudeguy]

average right now I'm seeing is  1 block per day for each ~3K PPS. A little more than cost of electricity on a standard PC.

Annnnnnnnnnnnd now the difficulty has changed ridiculous level since  even 2 days ago.
