While revision 6.0.1 is technically a bugfix release, with no apparent new features, much has changed "under the hood". - Sequential algorithms for repartitioning and (re)partitioning with fixed vertices have been improved. - Multithreading issues have been solved. - From now on, there is no separate "*_esmumps" version for interfacing with the MUMPS solver. The additional libraries can be generated by running "make esmumps" for the sequential libraries and "make ptesmumps" for the parallel libraries. Parallel static mapping and parallel direct k-way graph repartitioning with fixed vertices will be available in release 6.1. Scotch can be freely downloaded, under the terms of the CeCILL-C free software license. To ease the development, diffusion, and circulation of information regarding the SCOTCH project, most of its resources are hosted on the InriaGforge platform provided by INRIA. Please refer to the SCOTCH web pages at: https://gforge.inria.fr/projects/scotch/ http://www.labri.fr/~pelegrin/scotch/ ------------------------------------------------------- From: Dominik Meidner [log in to unmask] Date: September 19, 2014 Subject: Extreme Fluids, Germany, Nov 2014 We would like to announce the symposium "Simulation and Optimization of Extreme Fluids", November 10-12, 2014 at the IWH (Internationales Wissenschaftsforum) Heidelberg.

Both areas are closely related to each other and have found wide applications in engineering, industry, medicine, as well as life and earth sciences. This international conference aims to provide a forum for researchers from the world to present and exchange their latest research achievements on Inverse Problems and Optimal Control, as well as their applications. It also aims to promote collaborative research on Inverse Problems and Optimal Control between China and the rest of the world. This conference will encourage international collaboration and interactive activities on Inverse Problems and Optimal Control and provide an opportunity for young researchers to learn the current state of the art in the fields and present their recent research results as well. In addition to the invited talks, contributed talks are welcome. Moreover, some financial supports are available for young researchers and graduate students.
