The Concepts Evaluation Model VII CEM VII is the latest combat battle simulation in a long line of US army theater-level battle simulations. It has been developed under the auspices of the US army Concepts Analysis Agency CAA in Bethesda, Maryland. CEM VII is used by the CAA to access and optimize combat force capabilities. It can simulate months of theater land and air combat in a few hours on a super-computer. CEM VII can take several hours of supercomputer CPU time to run, which can be very costly. The goal for this project was to increase the performance of CEM VII in order to reduce the run time. This goal was achieved through two steps. First, a higher degree of vectorization-was incorporated into the kernel of CEM VII. Second, a process called Data Packing was eliminated from the computer code. The combined changes resulted in a 14.9 percent reduction in run time.
