# (WIP) Benchmark comparison between CGBN and Bigint
## Requirements
[google-benchmark](https://github.com/google/benchmark). On Arch Linux you can install using `sudo pacman -S benchmark`.
## Build
``` bash
git clone https://github.com/cassc/cuda-bigint-benchmark
cd cuda-bigint-benchmark
git submodule update --init --recursive
# Default architecture is 50, to change it to 86:
cmake -S . -B build -DCUDA_COMPUTE_CAPABILITY=86
# To enable verbose printing
cmake -S . -B build -DCUDA_COMPUTE_CAPABILITY=86 -DENABLE_DEBUG=ON
cmake --build build
```
## Run the benchmark
``` bash
./build/CudaBigIntBenchmark_benchmark
```
## Results
The following result is from a GTX 3060 Ti GPU.
``` bash
❯ ./build/CudaBigIntBenchmark_benchmark
