Abstract : In this document we describe how, with the use of Glenda, we were able to parallelize the ocean modeling program SWEM. After a description of Glenda and an introduction to the ocean model, we discuss how we parallelized the model. We first had to determine the array dependencies in the program in order to better understand the way we were going to handle data propagation. Once we had a grasp of how the data was to be propagated, there was a need to develop overlap definitions to help improve the readability of the code. But, we still encountered problems that had to be solved. Therefore, we had to use a wide assortment of debugging techniques to overcome these problems. With our problems finally solved and the program now complete, we tested our new version of SWEM and gathered results.
