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.
