2.1.4.giga31 Gigahorse 3.0 Node / Farmer

on GitHub

Fixed in this release:

• Random errors when farming a mix of old C1 to C20 and the new C30+ (~20 sec lookups and recv() timeout errors)
• Need to update remote compute servers as well to get the fix.

New since giga30:

• Gigahorse 3.0 plot format, C30 to C33
• Fixed an issue with remote compute where fail-over to another server did result in a lost lookup once every 100 sec. (ERROR: connect() failed with: Connection refused)

Limitations:

• The new C30 to C33 are only supported with the CUDA plotter (cuda_plot_k32_v3, 8G RAM / 4G VRAM minimum)
• Farming C30 to C33 is only supported with Nvidia GPU (starting with 900 series)
• K32 only for 3.0 format

Notes:

• Need to use cuda_plot_k32_v3 binary for plotting the new format (See here)
• Partial difficulty is now even more important for maximum farm size. Minimum recommended partial difficulty is 10k for the new 3.0 format.
• Using a too low partial difficulty will increase GPU load by a factor of 2, in the worst case.
• Higher -S can help with phase 3 plotting times, like -S 8 if you have enough VRAM.
• Use ProofOfSpace farm --diff 800000 to benchmark for solo farming.
• chia_recompute_server is backwards compatible to old clients, but needs to be updated for new clients running giga30.
• Both Node & Farmer & Harvester need to be updated at the same time to support 3.0 format.
• Lower levels of the 3.0 format to replace C16 to C18 will be released later (work in progress).

This release provides Chia Blockchain binaries to farm compressed plots created with the new plotters provided in this repository.

The compressed plot harvester and farmer are not compatible with the official Chia node, it only works together with the Gigahorse node. However it's possible to use a wallet from the official Chia repository, instead of the Gigahorse binary wallet.

Both NFT and OG plots are supported, as well as solo and pool farming (via the official pool protocol). Regular uncompressed plots are supported as well, so you can use the Gigahorse version while re-plotting your farm.

The dev fee is as follows:

• 3.125 % when using GPU(s) to farm compressed plots
• 1.562 % when using CPU(s) to farm compressed plots
• 0 % for regular uncompressed plots

The following packages are needed to run on Linux: sudo apt install ocl-icd-libopencl1

Make sure to choose the correct version for your system, see uname -m, usually it's x86_64. aarch64 is the same as arm64.

On Windows:

• You might have to install latest Microsoft Visual C++ Redistributable: https://aka.ms/vs/17/release/vc_redist.x64.exe

Note: See limit-gpu-usage on how to select an OpenCL platform if you have multiple platforms (excluding Nvidia).
