gpu-groth16-prover-3x's Introduction

GPU Groth16 prover (3x faster than CPU)

This is a GPU Groth16 prover that won the 2x speedup prize. It follows the template from the reference.

This prover requires a substantial amount of RAM to use. The reference machine has 32GB.

This prover has a slow preprocessing step! Note the changed instructions below.

Dependencies

The code should compile and run on Ubuntu 18.04 with the following dependencies installed:

sudo apt-get install -y build-essential \
    cmake \
    git \
    libomp-dev \
    libgmp3-dev \
    libprocps-dev \
    python-markdown \
    libboost-all-dev \
    libssl-dev \
    pkg-config \
    nvidia-cuda-toolkit

Building on MacOS is not recommended as CUDA support is harder to use. (Apple mostly ships with AMD.)

Build

./build.sh

Generate parameters and inputs

./generate_parameters
./main MNT4753 preprocess MNT4753-parameters # IMPORTANT PREPROCESSING STEPS
./main MNT6753 preprocess MNT6753-parameters

The preprocessed filenames are currently hardcoded to MNT4753_preprocessed and MNT6753_preprocessed.

Run

./main MNT4753 compute MNT4753-parameters MNT4753-input MNT4753-output
./main MNT6753 compute MNT6753-parameters MNT6753-input MNT6753-output
./cuda_prover_piecewise MNT4753 compute MNT4753-parameters MNT4753-input MNT4753-output_cuda
./cuda_prover_piecewise MNT6753 compute MNT6753-parameters MNT6753-input MNT6753-output_cuda

Check results

sha256sum MNT4753-output MNT6753-output MNT4753-output_cuda MNT6753-output_cuda
