Zusammenfassung: | Eigenvalue problems arise in many fields of physics and engineering science for example in structural engineering from prediction of dynamic stability of structures or vibrations of a fluid in a closed cavity. Their solution consumes a large amount of memory and CPU time if more than very few (1-5) vibrational modes are desired. Both make the problem a natural candidate for parallel processing. Here we shall present some aspects of the solution of the generalized eigenvalue problem on parallel architectures with distributed memory. The research was carried out as a part of the EC founded project ACTIVATE. This project combines various activities to increase the performance vibro-acoustic software. It brings together end users form space, aviation, and automotive industry with software developers and numerical analysts. |
