[XPM] Pool mining primecoin using DigitalOcean (VPS)

[Vorksholk]

Does anyone use Chemisist's rebuild?

https://github.com/Chemisist/primecoin

I've git cloned it and recompiled it on the smallest droplet (512MB 1 core) an hour ago. Didn't even had to re-size it to more memory, temporarily creating and destroying swap file for compilation, compiled while still mining.

Excellent results, it's doubled pps to previous version. It varies 250-350 pps. Recommended.

Same. Getting 300-450pps

How do I compile that?

I have the original Sunny build with the sieve update in my VPS'

Thanks for the input!

Well, somebody has to wright the full howto, so since there are no other volunteers...

First, it's easier to create the new smallest droplet. If you want to do it on the existing one you can do it also, I'll make cleaer the difference.

Create smallest droplet (512MB/ 1 CPU), select your region, select Ubuntu 13.04 x64. It has no desktop, we don't need it and desktop may make mining just a bit slower. Connect to a droplet console.

First change the root password, it's awkward to use default DigitalOcean password, hard to remember, type:

Code:

passwd

and enter the new password twice.
It's not recommended to work as root under linux, you can easily mess things up. Create a new user and make it a sudoer so it can do what root can, but safely. Enter a new password for the user and few enters, no need to enter other info:

Code:

adduser <newusername>

Make a newly created user a sudoer:

Code:

adduser <newusername> sudo

Now logoff and login again as a newly created user for the first time:

Code:

logoff

Then install all the apps and libraries you'll need in one step, -y at the and saves you for having to confirm things:

Code:

sudo apt-get install git build-essential libssl-dev libboost-all-dev libdb5.3++-dev -y

If you already had a droplet earlier, you begin here. Remove the previous source of the primecoin, if you created new instance skip only this one step:

Code:

rm -rf primecoin

Now get fresh software from Chemisist repo on GitHub:

Code:

git clone https://github.com/Chemisist/primecoin.git

Create temporary swap file and mount it as swap, this avoids compilation errors which are all due to the lack of memory, 512MB is not enough for compilation:

Code:

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

Move where the action takes place:

Code:

cd ~/primecoin/src

Compile the software, this takes a while, go get a cup of coffee:

Code:

make -f makefile.unix USE_UPNP=-

Unmount and remove the swap file, we don't need it for normal usage:

Code:

sudo swapoff /swapfile
sudo rm /swapfile

Create directory for wallet, configuration and logs:

Code:

mkdir ~/.primecoin

Create configuration file. For newbies, just type the first line, you'll get a prompt for second and third line:

Code:

echo "rpcuser=ARPCUserName
rpcpassword=SomethingReallyLongOK
gen=1" > ~/.primecoin/primecoin.conf

Move newly created executable to it's permanent place, where it will also be in the path:

Code:

sudo mv primecoind /usr/local/bin/.

Go home and start mining:

Code:

cd ~
primecoind --daemon

Watch the statistics and also get info about newly mined blocks:

Code:

watch 'primecoind listtransactions & primecoind getmininginfo'

This should be it. You should have 300 pps in a few minutes. Tips are appriciated.

Been running 20cores at DO for 12 hours, only been able to find 1 block so far.
I don't think it is feasible to mine with cloud instances, it cost too much and the return is too little.

I agree - I pulled my clusters today... Price dropping too fast whilst getting too hard to find blocks

[rigelugh]

I mined 2 blocks with my single 1CPU/512 MB VPS on digital ocean in the time that I was asleep/at work yesterday.

My AMD Phenom mined 0 though it didn't have internet while I was at work all day.

Since I got hom, I've started two more single core instances, using Chemisist's builds. So I now have three, one running the same build from Sunny that gave me the 2 blocks.

Haven't found anything so far. It's only cost me $0.40 to run all this, though, so it's worth it (to me).

i pulled mine as well.

Just a reminder, if you decided to stop mining on DigitalOceans you must destroy the instances.
 otherwise it would continue to charge you.

Please refrain from mining on momento. Our seed nodes are located there. If you kill the cluster you would cause me a lot of trouble.

I made a deposit there...0.1btc, what do I do with that then? :/
How/why would it hurt to mine on say one 8 core instance? I'm not super greedy, but don't feel like wasting money.

I think momento's cluster is very small, if I run mining in 2 vms, they basically each generate half compared to just run mining in 1 vm.

So don't try to consume all cpu there, I already felt slow there today. Mine some, I think you should be able to make the money back. But I would advise other people refrain from mining there.

Thanks Sunny, yeah, I'll try to make that back and then stop mining there.

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

this just gives a blank screen?

How long are you waiting? It seemed to take a while to generate the swap file.

I have a basic mining question.

I've been moving all my xpm to my local system which is a vdi running ubuntu as I have a mac.  I haven't yet optimized  this miner with Chemisists build and would like to but I'm worried about my existing wallet that has all my xpm.  Do I just need to back up the wallet.dat file to another directory, do the rebuild, then copy back and expect to be able to open it and access all my xpm or is there some other process?

Backuping the wallet is always a good idea, but you don't need to do it for a rebuild. Old and new executable share the same wallet, to be exact every time primecoin software starts it checks to find the wallet in the expected place and uses it if it finds one, or creates new one if there is no wallet there. It never overwrites new wallet over the old one.

Excellent - that's what I was assuming but wanted to be sure.  Thanks!

Difficulty is going up, and miners are improving. Looks we like have found some new world records!

https://bitcointalk.org/index.php?topic=253409.60

I wonder if any of these were mined on DigitalOcean instances?

EDIT: If you mined one of the record blocks we'd love to hear about it!

[rethaw]

I switched to Chemisist's build for now. It appears to get a higher pps by around 25%.

Code:

git clone https://github.com/Chemisist/primecoin chem
cd chem/src
make -f makefile.unix USE_UPNP=-
primecoind stop
sleep 5
sudo mv primecoind /usr/local/bin/.
primecoind --daemon
watch 'primecoind listtransactions & primecoind getmininginfo'

Can someone please post guide for using creating a amazon EC2 free one?  I am a noob at EC2.

Want to help me out, no coffee right now .

Quick how to is fine, it can be vague.

Found this little bash script from reddit
https://gist.github.com/anonymous/5987007

It show your balance, recent transactions and pps, just like the command:

Code:

watch 'primecoind listtransactions & primecoind getmininginfo'

Simpe guide for using it in user's home directory

Code:

cd
wget https://gist.github.com/anonymous/5987007/raw/5f92a73e579f448a1af0e7b40ec45974e54ab4c9/miningstats.sh
chmod +x ./miningstats.sh
watch ./miningstats.sh

And the script outputs like this:

Code:

[+] Your balance is: 0.00000000
[+] Recent transactions are (amount / state)
15.79000000 - orphan
[+] You're currently mining at 149 pps

Alright, sorry.
