Locally structured, overset meshes, as used in the Center’s principal code PlasComCM, provide a potential compromise between meshing flexibility and stencil-based efficiency. They also offer logical simulation units for high-order/high-resolution discretizations, decomposing data in memory, representing disparate physics, and transformations to realize performance. This Deep Dive will provide a detailed look at our overset mesh implementation in codelet-DD, a model for PlasComCM. Participants will examine the code structure, construct their own mesh, alter the governing equations, run it on a platform of interest, or analyze it with tools designed to facilitate performance at scale. The same codelet-DD will be analyzed by VectorSeeker, an XPACC vectorization analysis tool used within the Center. Tasks will be designed to facilitate the hands-on experience of participants. Center code docents will provide support and guidance.
