I made a fork of PDAL with GPU acceleration for NVIDIA GPUs! On common pipelines, you can get anywhere from 2 to 14x speed improvements over stock PDAL. It's a drop in replacement, just use npm i gpupdal to get it and use gpupdal for any command where you would use pdal.

(PDAL is an open source library for working with point cloud data, for the uninitiated)
