We are exploiting massively parallel computing to mine Fermi gamma-ray data for pulsars using the most sensitive tests available to uncover faint signals. Graphical Processing Units (GPUs) are ideal for accelerating optimized coherent searches for periodicity, previously computationally prohibited. We have already achieved two order-of-magnitude acceleration in these computations as applied to X-ray pulsar searches, and are now bringing this new technology to search Fermi data. We hope to discover fainter pulsars missed by previous searches that used less sensitive methods. We will review the methods and status of our ongoing program.
