We describe a variety of optimizations of GTC, a 3D gyrokinetic particle-in-cell code, for the Cray X1E. Using performance data from multiple points in the optimization process, we compare the relative importance of different optimizations on the Cray X1E and their effects on Cray XT3 performance. We also describe the performance difference between small pages and large pages on the XT3, a difference that is particularly significant for GTC.
