«The GNU Profiling tool is part of the GNU compiler package which is freely available under the GNU General Public License. It was used to take the initial profile of the code, and was able to provide subroutine-level results about the most time consuming parts of the code. The information from the GNU Profiler was used to narrow down the search for the sections of code to be offloaded to the GPU.»
