We describe a software library for dynamic load balancing of finite element codes; The application code has to provide the current distributed mesh and information on the calculation and communication requirements, and receives from the library all necessary information to re-allocate the application data. The library computes a new partitioning, either via direct mesh migration or via parallel graph re-partitioning, by interfacing to the ParMetis or Jostle package. We describe the functionality of the DRAMA library and we present some results.
