This repository is part of the work presented in High-performance watershed delineation algorithm for GPU using CUDA and OpenMP.
Probably the simplest way to build the measurement application (using the Nvidia CUDA Compiler):
nvcc -std=c++11 -O3 -Xcompiler -fopenmp *.cpp *.cu -lgdal -o time_measurement
GDAL is the only external dependency required (used here to load and save geospatial raster data).
