Tutorial: Virtual GPU Miner (Google Cloud)


Running the GPU miner in this example is done using Google Cloud.

Step 1: Create VM and Allow Port Access

From the Console, navigate to Compute Engine>>>VM Instances from the main menu on the top left.

Create a new instance.


Zone: asia-southeast1-b (or any other region that supports GPU miners)

Machine Type: Custom , 6 CPU, 10 GB and 1 Nvidia Tesla P4

OS: Debian GNU/Linux 10

Disk Type: SSD persistant disk

Disk Size: 100 GB

Firewall Settings: Allow HTTP traffic


NOTE: If it's your first time using Google Cloud, you may encounter an error after creation that requires you to increase your GPU Quota limits. You can do so by following this Stack Overflow solution.

Next in order to open the ports on your VM, you will need to create a Firewall Rule. You can navigate there by going to VPC Network>>>Firewall from the main menu. Once there, create a new firewall rule that will match the network tag that was created by the Firewall Setting from earlier:


Be sure to fill out the fields exactly as above.

Enable and create the rule. Once you do so, your ports will be open to view the multiverse being created by your miner (covered at the end of this tutorial).

Step 2: Access VM & Install Nvidia CUDA Drivers

SSH into your VM using your own terminal and enter the following commands:

sudo apt update -y
sudo apt install -y git net-tools vim tmux lshw jq wget curl ca-certificates apt-transport-https gnupg2 software-properties-common

curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/debian buster stable"
sudo apt update -y

sudo apt-get install -y docker-ce docker-ce-cli containerd.io

sudo systemctl start docker

export DEBIAN_FRONTEND=noninteractive
apt -y install linux-headers-$(uname -r) build-essential
echo blacklist nouveau > /etc/modprobe.d/blacklist-nvidia-nouveau.conf

systemctl reboot

sudo apt install -y linux-headers-4.19.0-10-cloud-amd64

sudo su root
wget http://us.download.nvidia.com/tesla/440.33.01/NVIDIA-Linux-x86_64-440.33.01.run

chmod +x NVIDIA-Linux-x86_64-440.33.01.run

./NVIDIA-Linux-x86_64-440.33.01.run -s
# -s is silent mode which prevents pesky pop ups and questions
# you may see two ERROR messages after running this command. Feel free to ignore and move on 

Step 3: Install Docker for Nvidia

While still in root@ from the earlier sudo su root command in Step 2:

distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | sudo apt-key add -
curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.list | sudo tee /etc/apt/sources.list.d/nvidia-docker.list

sudo apt-get update && sudo apt-get install -y nvidia-container-toolkit
sudo systemctl restart docker

sudo reboot 
# this is a required step and will end your session, so reopen a new session to continue 

sudo su root

docker run --gpus all nvidia/cuda:10.0-base nvidia-smi
# this step verifies that docker is installed and recognizes your GPU.

Step 4: Build Miner image



The following GitHub repo is maintained by independent, non-Overline affiliated, members of our community. Use at your own discretion.

git clone https://github.com/trick77/bcnode-gpu-docker bcnode-gpu-docker && cd $_


vim ./config 
# update the "miner key" and "scookie" values in this file,

Step 5: Add latest db snapshot to _data folder


Ephemeral Storage / DB Snapshot

Using this snapshot is recommended only if you would like to speed up your sync process.
We STRONGLY encourage users to mine the full multichain db from scratch, if possible.

apt install unzip
wget https://community.multichains.org/_easysync_db.zip && ./import-db.sh ./_easysync_db.zip

Step 6: Start BC Miner


That's it! below are some commands to use post-running the miner.

To view logs:

sudo docker logs -f bcnode --tail 100

To stop miner*:

sudo ./cleanup.sh

To re-pull the latest db snapshot:

sudo wget https://community.multichains.org/_easysync_db.zip

sudo ./import-db.sh ./_easysync_db.zip

To re-pull the latest docker image:

sudo ./build-images.sh

To restart miner after stopping*:

sudo ./start.sh

To view your multiverse:

Go to [YOUR.EXTERNAL.IP]:3000 in your browser.

*NOTE: You will need to be in the directory tmp/bcnode-gpu-docker/ to run these commands.
