summary

Describes porting interferometry-based signal processing used at CERN (Butterworth filter, Hilbert transform, Savitzky–Golay smoothing) from CPU to NVIDIA GPUs using CuPy, then later a C implementation. Explains the steps taken to adapt these algorithms to run in parallel on GPUs, measures performance as data size increases, and discusses optimizations to meet sub-second processing for thousands of target points.
