MadMax

The Madmax plotter offers two modes:

• diskplot: Requires a fast SSD for temporary space, about 256 GiB used per plot.
• gpuplot: GPU plotting, this requires a recent Nvidia GPU with at least 8 GB of VRAM.

Machinaris uses an enhanced Plotman plotting manager to interface with plotting backends: bladebit, chia and madmax. NOTE: Machinaris provides a full WebUI with plotting management, monitoring and remote control.

Config

Here is a good starting point for Plotman config when using madmax. Start with a single Madmax plot allowed at one time, dial up threads and buckets to match your hardware:

WARNING: Do not try to run madmax with as many concurrent plots (tmpdir_max_jobs and global_max_jobs) as the official chia plotter. Your computer will explode!

Advanced Usage

Here are some advanced settings for Madmax.

Disable Building

Madmax is built when the container launches, so if you want to disable plotter build for fullnodes & plotters (only in Chia, Chives, and MMX, also not happening on harvesters regardless of blockchain), then you can set env var: madmax_skip_build with value true.

N-plots

While the default behavior is for Plotman (manager) to invoke Madmax in an infinite loop, asking for a single plot each time, it is possible to have Plotman ask Madmax to make exactly N plots.

Set a n: X value under the madmax: section of Setting | Plotting page. Only use case is:

1. You have a drive where you know want exactly X more plots made, let it run overnight, no failed attempts due to lack of space.
2. You set n: X, then start Plotman.
3. Plotman invokes Madmax with n of X. Madmax starts plotting.
4. You immediately stop Plotman and remove the n: from your Settings | Plotting page, returning to default of one at a time (infinitely).
5. With Plotman stopped, Madmax will plot those X plots then stop itself. Another run of Madmax won't be started.

The downside is that Plotman will log those X plots as if it was one long job, which messes a bit with stats. No big deal though.

Chives

It is possible to set k values of 29,30,31 for plotting Chives. Please ensure you set network_port=9699 if you do so.

Stagmax

While generally Madmax should plot one at a time, it may be possible to plot concurrently. See this Stagmax video:
