Data should be placed in data/, which is ignored by git.

Build

• mkdir build && cd build && cmake .. && make -j8

Benchmarks

• Usage ./run $data. data can be a image or a folder with multiple images. The benchmarks will be individually run for each image. The results are store in a csv (one by image) in a results-\* folder.

• Then you can use visu_benchmark.ipynb to visualize them.

Results

• Step 1:
  • gpu1: naive version, broken bench
  • gpuv1: first optimization
  • very_optimized: second optimization, broken bench
  • very_optimized_fixed: second optimization
