\frametitle{Scope}
\item Make current CPU functions available for use on GPU
\begin{itemize}
\item Add appropriate prefixes to function definitions
\item Make use of multiple parallel threads to execute each function
\end{itemize}
\item Ensure correctness of each GPU available function by matching results to the corresponding CPU function
\item Compare performance of GPU available functions to CPU functions

\begin{enumerate}
\item \label{PUC_SimulatingParticles} The software will be used by researchers wishing to simulate large numbers of particles interactions with materials. The researcher sets simulation parameters, including the number of particles, their lifetime, and the material properties before running the simulation. On completion, the program gives back a map of where each particle traveled, so researchers can study where the particles are most probably to end up.
