Title: Locating Dark Matter with MilkyWay@home Abstract: MilkyWay@home is a 0.5 PetaFLOPS volunteer computing platform that optimizes the parameters in a model, given a set of data and a method for measuring goodness of fit of the data to the model. We have used to find the density distribution of stars in tidal streams, and in particular the Sgr dwarf tidal stream. We are building the infrastructure to measure the distribution of dark matter in the Milky Way by comparing n-body simulations to actual tidal debris in the halo.
