ZPrize MSM on GPU Reference Test Harness
Example and reference testing harness for the "Accelerating MSM on GPU" challenge in ZPrize 2022.
Build
The CUDA sppark from Supranational has a Rust binding. To install the latest version of Rust, first install rustup. Once rustup is installed, install the Rust toolchain by invoking:
rustup install stable
After that, use cargo, the standard Rust build tool, to build the libraries:
git clone https://github.com/z-prize/test-msm-gpu.git
cd test-msm-gpu
cargo build --release
Test
To run a test of an MSM of 2^15 random points and scalars on the BLS12-377 curve, run:
cargo test --release
Bench
This repository specifies default features corresponding to the ZPrize competition. To run the target benchmark of the competition (2^26 random points on BLS12-377), run:
cargo bench
To specify the window size in the Pippenger algorithm, pass the flag CXXFLAGS="-D WBITS=17". For BLS12-377, a window of size 17 seems to give the best results but it is up to competitors to specify it.
