chia-plotter (pipelined multi-threaded)

This is a new implementation of a chia plotter which is designed as a processing pipeline, similar to how GPUs work, only the "cores" are normal software CPU threads.

As a result this plotter is able to fully max out any storage device's bandwidth, simply by increasing the number of "cores", ie. threads.

Usage

Check discord for support: https://discord.gg/rj46Dc5c

For <poolkey> and <farmerkey> see output of `chia keys show`.
<tmpdir> needs about 220 GiB space, it will handle about 25% of all writes. (Examples: './', '/mnt/tmp/')
<tmpdir2> needs about 110 GiB space and ideally is a RAM drive, it will handle about 75% of all writes.
Combined (tmpdir + tmpdir2) peak disk usage is less than 256 GiB.
In case of <count> != 1, you may press Ctrl-C for graceful termination after current plot is finished.

Usage:
  chia_plot [OPTION...]

  -n, --count arg      Number of plots to create (default = 1, -1 = infinite)
  -r, --threads arg    Number of threads (default = 4)
  -u, --buckets arg    Number of buckets (default = 256)
  -t, --tmpdir arg     Temporary directory, needs ~220 GiB (default = $PWD)
  -2, --tmpdir2 arg    Temporary directory 2, needs ~110 GiB [RAM] (default = <tmpdir>)
  -d, --finaldir arg   Final directory (default = <tmpdir>)
  -p, --poolkey arg    Pool Public Key (48 bytes)
  -f, --farmerkey arg  Farmer Public Key (48 bytes)
      --help           Print help

Make sure to crank up <threads> if you have plenty of cores, the default is 4. Depending on the phase more threads will be launched, the setting is just a multiplier.

RAM usage depends on <threads> and <buckets>. With the new default of 256 buckets it's about 0.5 GB per thread at most.

RAM disk setup on Linux

sudo mount -t tmpfs -o size=110G tmpfs /mnt/ram/

Note: 128 GiB System RAM minimum required for RAM disk.

How to Verify

To make sure the plots are valid you can use the ProofOfSpace tool from chiapos:

git clone https://github.com/Chia-Network/chiapos.git
cd chiapos && mkdir build && cd build && cmake .. && make -j8
./ProofOfSpace check -f plot-k32-???.plot [num_iterations]

Future Plans

I do have some history with GPU mining, back in 2014 I was the first to open source a XPM GPU miner, which was about 40x more efficient than the CPU miner. See my other repos.

As such, it's only a matter of time until I'll add OpenCL support to speed up the plotter even more, keeping most of the load off the CPUs.

Clear Linux

Read install file

Ubuntu 20.04

sudo apt install -y libsodium-dev cmake g++ git
# Checkout the source and install
git clone https://github.com/madMAx43v3r/chia-plotter.git 
cd chia-plotter

git submodule update --init
./make_devel.sh
./build/chia_plot --help

The binaries will end up in build/, you can copy them elsewhere freely (on the same machine, or similar OS).

macOS

First you need to install a package manager called Brew and Xcode OR CommandLineTools.

# Alternative way to download CommandLineTools on Terminal:
xcode-select --install

brew install libsodium cmake git autoconf automake libtool wget

# If you downloaded Xcode run these:
sudo ln -s /usr/local/include/sodium.h /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/
sudo ln -s /usr/local/include/sodium /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/

# If you downloaded CommandLineTools run these:
sudo ln -s /usr/local/include/sodium.h /Library/Developer/CommandLineTools/usr/include
sudo ln -s /usr/local/include/sodium /Library/Developer/CommandLineTools/usr/include

brew link cmake

Confirm which directory you have on YOUR Mac before applying following commands

wget https://raw.githubusercontent.com/facebookincubator/fizz/master/build/fbcode_builder/CMake/FindSodium.cmake -O /usr/local/opt/cmake/share/cmake/Modules/FindSodium.cmake

wget https://raw.githubusercontent.com/facebookincubator/fizz/master/build/fbcode_builder/CMake/FindSodium.cmake -O /opt/homebrew/Cellar/cmake/3.20.3/share/cmake/Modules/FindSodium.cmake

git clone https://github.com/madMAx43v3r/chia-plotter.git 
cd chia-plotter
git submodule update --init
./make_devel.sh
./build/chia_plot --help

Running in a Docker container

In some setups and scenarios, it could be useful to run your plotter inside a Docker container. This could be potentially useful while running chia-plotter in Windows.

To do so, install Docker in your computer and them run the following command:

docker run \
  -v <path-to-your-tmp-dir>:/mnt/harvester \
  -v <path-to-your-final-dir>:/mnt/farm \
  odelucca/chia-plotter \
    -t /mnt/harvester/ \
    -d /mnt/farm/ \
    -p <pool-key> \
    -f <farm-key> \
    -r <number-of-CPU-cores>

💡 You can provide any of the plotter arguments after the image name (odelucca/chia-plotter)

In a Linux benchmark, we were able to find that running in Docker has only 5% performance impact than running in native OS.

For Windows users, you should check if your Docker configuration has any RAM or CPU limits. Since Docke runs inside HyperV, that could potentially constrain your hardware usage. In any case, you can set the RAM limits with the -m flag (after the docker run command).

Regarding multithread in Docker

While running in Windows, you may need to proper configure your Docker to allow multi CPUs. You can do so by following this article

In a nutshell, you could also pass the --cpus flag to your docker run command in order to achieve the same result.

So, for example, the following command:

docker run \
  -v <path-to-your-tmp-dir>:/mnt/harvester \
  -v <path-to-your-final-dir>:/mnt/farm \
  -m 8G \
  --cpus 8 \
  odelucca/chia-plotter \
    -t /mnt/harvester/ \
    -d /mnt/farm/ \
    -p <pool-key> \
    -f <farm-key> \
    -r 8

Would run your plotter with 8 CPUs and 8GB of RAM.

Known Issues

Doesn't compile with gcc-11, use a lower version.
Needs at least cmake 3.14 (because of bls-signatures)
