Benchmark of MRI-NUFFT

This are a collection of script to perform benchmarking of MRI-NUFFT operations.

They rely on the hydra configuration package and hydra-callback for measuring statistics. (see requirements.txt)

To fully reproduce the benchmarks 4 steps are necessary:

  1. Get a Cartesian Reference image file, name cpx_cartesian.npy
  2. Generates the trajectory files python -m trajectory.py
  3. Run the benchmarks. Currently are available:
  • The Performance benchmark, checking the CPU/GPU usage and memory footprint for the different backend and configuration perf folder.
  • The Quality benchmark that check how the pair trajectory/backend performs for the reconstruction. in qual folder
  1. Generate some analysis figures using perf_analysis.py
