Abstract

Parallel FEM-applications on distributed memory systems with changing work load and communication requirements need parallel re-partitioning methods to achieve dynamic load balancing. DRAMA is a research project which aims to develop a software library providing tools to achieve this goal for unstructured FEM-problems on parallel computers supporting message passing.

Applications will provide their computation and communication requirements, via the DRAMA cost function, and will receive information on how to re-allocate data from the library. The DRAMA cost function allows to model dynamically changing computational and communication requirements. Also the machine architecture will be taken into account. This paper focuses on the cost function that will be used in the library and also on the library interface.
