This project is using git submodules, you thus need to clone the submodule in addition to the main project. To do so run the following command:

$ git submodule init
$ git submodule update

In order to build this project you need to install the cmake build tool.

Run the following command to build the project using cmake

$ mkdir build
$ cd build
$ cmake ..

Then you need to compile the programs

$ cd build
$ make all

This will create four binaries cpu, gpu_1, gpu_2, gpu_3 and gpu_final.

All of the four binaries take as the first argument the destination file containing the cloud point as a csv and as a second argument the source file containing the cloud point as a csv.

Here is an exemple:

$ cd build
$ ./cpu destination.csv source.csv

To run the benchmark you first need to compile it using this command:

$ cd build
$ make bench

Then you can execute it this way:

$ cd build
$ ./bench

You can use the -h option to see the list of arguments the bench binary takes.
