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 allows one to write parallel programs that
operate on unstructured meshes with only minimal knowledge of
parallel computing, while making it possible to achieve excellent
scalability even for complex applications. Charm++'s message-driven
model enables computation/communication overlap, while its run-time
load balancing capabilities make it possible to react to the
changes in computational load that occur in dynamic physics
applications. The framework is highly flexible and has been
enhanced with numerous capabilities for the manipulation of
unstructured meshes, such as parallel mesh adaptivity and collision
detection.
