[XPM] Pool mining primecoin using DigitalOcean (VPS)

[ivanlabrie]

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!

Quoting myself, do I just do this all over again but replace the url with chemisist's github?

apt-get install git
git clone https://github.com/Chemisist/primecoin
apt-get install build-essential libssl-dev libboost-all-dev libdb5.3++-dev -y
cd ~/primecoin/src
make -f makefile.unix USE_UPNP=-
mkdir ~/.primecoin
echo "rpcuser=ARPCUserName
rpcpassword=SomethingReallyLongOK
gen=1" > ~/.primecoin/primecoin.conf
sudo mv primecoind /usr/local/bin/.
primecoind --daemon
watch 'primecoind listtransactions & primecoind getmininginfo'

delete old primecoin source folder, git clone, make, strip, copy to your home dir

I get this error.

Code:

In file included from main.cpp:16:0:
prime.h: In constructor ‘CSieveOfEratosthenes::CSieveOfEratosthenes(unsigned int, unsigned int, uint256, CBigNum&)’:
prime.h:109:6: error: ‘prevWeaveTime’ was not declared in this scope
prime.h:110:3: error: ‘prevTotalTime’ was not declared in this scope
make: *** [obj/main.o] Error 1

Chemisist just made some changes to the prime.h file to add those declarations or remove them.

Just do the following and recompile:
git reset --hard HEAD
git pull
then make -f etc.....

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.

make -f makefile.unix USE_UPNP=-

rpcpassword=SomethingReallyLongOK
gen=1" > ~/.primecoin/primecoin.conf
sudo mv primecoind /usr/local/bin/.
primecoind --daemon
watch 'primecoind listtransactions & primecoind getmininginfo'

I just removed the primecoin folder (not the .primecoin) And compiled the Chemisist rebuild with

make -f makefile.unix USE_UPNP=-

Then run the daemon, BUT nothing changed it's still fluctuates between ~100-130 pps. Anyone have an idea about that?

Works! Thanks so much!

edit: after Primecoin server starting I get some blocks downloaded and then

Code:

"blocks" : 889,
    "currentblocksize" : 0,
    "currentblocktx" : 0,
    "errors" : "",
    "generate" : true,
    "genproclimit" : -1,
    "primespersec" : 0,
    "pooledtx" : 0,
    "testnet" : false

error: couldn't connect to server

Yes.

You can simply make a new droplet. Better to follow itod's directions though.

chemisist release is not an official release, use at own risk.

Strange for DigitalOcean instance to lose connectivity. Maybe it has not, but you cannot connect to server for some other reason?
Try restarting the primecoind

Code:

primecoind stop
primecoind --daemon

I have tried installing clean on a new droplet, still getting the same error. Restarting the daemon doesn't change the result. Noticed if I keep typing

Code:

primecoind --daemon 

I reconnect and then disconnecting again. In the process some blocks get downloaded.

Edit: Solved

OK since so many people have asked about the provider I use, it's https://momentovps.com/ .
Note that my first instance got 1000 pps until the second instance started mining. I currently have 6 instances running, each averaging around 450 - 500pps. One instance is running Chemicist's mod getting the same performance. I noticed no performance difference between 1GB and 256MB RAM, but it's possible there are some load balancing rules favoring instances with more RAM.

So if too many people join we will probably kill the cluster (I don't know which hardware is used, there's a topic here but it's pretty old). But since you have to install the OS on each server by hand via VNC (can't clone disks afaik, well now that i think about it you could attach two disks to one server and then clone the disk in linux; detaching drives doesn't work you have to delete the server, oh and their interface is a mess generally), I doubt too many people in this thread will make use of this provider.  

And before you get your hopes up, I got no blocks since I started mining there.

Is there anyone using Chemisist version on a 1 core/1 gig droplet? What is your pps? Mine is stucked at 100-130 pps whereas it's supposed to be far more than that.

[BTC-Market]

Chemisist's version kept almost instantly crashing on an 8 core droplet, not even enough time to see how much it was pumping. I tried to update it first, thought I screwed something up, so I destroyed the Droplet and created a new one to install it from scratch. It would still insta-crash. Reverted back to Sunny's latest build

Works for me. I'm getting 2500 pps going up.

So many releases on this thread, where to find Sunny's latest build?

I didn't see any different in PPS with Chemisist's git.

With the 8 core droplet?

For anyone curious, here is how it looks on the amazon free instance (micro)



I will check out the other amazon high CPU instances soon to see what they can do.

Edit: This is using primecoin from github by the way.

yes, but it is down to around 2000 now
