ABSTRACT

Unstructured meshes are used in many engineering applications with irregular domains, from elastic deformation problems to crack propagation to fluid flow. Because of their complexity and dynamic behavior, the development of scalable parallel software for these applications is challenging. The Charm++ Parallel Framework for Unstructured Meshes (ParFUM) allows one to write parallel programs that operate on unstructured meshes with minimal knowledge of parallel computing, while making it possible to achieve excellent scalability even for complex applications. In this talk, I will introduce ParFUM and its features, such as mesh adaptivity and contact detection, and discuss some of the performance challenges inherent in dynamic applications, along with approaches for overcoming those challenges.
