         parallelization with OpenMP offers an easy way for the user to harness their power. As a result,
         tools for automatic differentiation (AD) should be able to deal with such codes in a fashion that
         preserves their parallel nature also for the derivative evaluation. In this paper, we explore this
         issue using a plasma simulation code. Its structure, which in essence is a time stepping loop with
         several parallelizable inner loops, is representative of many other computations. Using this code as
         an example, we develop a strategy for the efficient implementation of the reverse mode of AD with
         trace-based AD-tools and implement it with the ADOL-C tool. The strategy combines checkpointing at
         the outer level with parallel trace generation and evaluation at the inner level. We discuss the
         extensions necessary for ADOL-C to work in a multithreaded environment and the setup necessary for
         the user code and present performance results on a shared-memory multiprocessor.",
