XMR/Monero mining using XMR-STAK

The new version of XMR-STAK that supports Monero7 is out:
https://github.com/fireice-uk/xmr-stak/releases

The PoWs They Are a-Changin'

So here is what I did to get it going on the Community Release.
The first step is to DL the source and compile it:

Code:

# Build XMR, from https://github.com/fireice-uk/xmr-stak/blob/master/doc/compile_Linux.md
cd /home/m1/xmr
git clone https://github.com/fireice-uk/xmr-stak.git
#mkdir xmr-stak/build
cd xmr-stak
cmake .
make install

The next thing you want to do is just execute the binary:

Code:

cd bin
./xmr-stak

It will do a one-time prompt for coin, pools, addr.worker, pass and create the necessary configuration files. These new configuration files are NOT compatible with previous versions so this must be done. The next step is to setup nvOC for the memory changes:

Code:

# Configure Memory for hugepages
sudo vi /etc/sysctl.conf
# Add line
vm.nr_hugepages=128
# Set user limits
sudo vi /etc/security/limits.conf
# Add lines
* soft memlock 262144
* hard memlock 262144
# Reboot
sudo shutdown -r now

Note: I did all of the steps above while my rig was mining. The final thing is to modify 0miner to strip out all of the old configuration file generation stuff and get down to just the basics. One could go to the trouble of modifying all of the existing code for this in 0miner to make it compatible with the new version of XMR-STAK but I do not have the time to do it so I just went with a stripped down 0miner to just launch the miner and let the user launch it as above to do the one-time config file generation. That 0miner code is:

Code:

if [ $COIN == "XMR" ]
then
HCD='/home/m1/xmr/xmr-stak/bin/xmr-stak'
cd /home/m1/xmr/xmr-stak/bin
screen -dmSL miner $HCD
fi

Hope this helps.

Great work (as always) Stubo. Thanks for providing detailed guide.

When you have time, could you check/review this new miner at:

Apparently is 20% faster and more stable than msft
