Bilateral Contracts with Industry

The research department of VolksWagen AG uses the OpenFOAM fluid dynamics code, among other software. The parallel version of this code relies on Scotch to distribute mesh data across processors. When running their simulations, the engineers of VW in charge of running numerical simulations have noticed load imbalance among the processors, and would like to have this problem solved in order to achieve better machine utilization.

The purpose of this contract is to investigate the potential causes of the evidenced imbalance, and to find remedies to it. The proposed solutions should be integrated in the trunks of Scotch and/or of OpenFOAM . This contract started in April and ended in December.
