News ================================================================= 3.1 Einstein Toolkit Release ---------------------------- Announcement on Hyperspace@AEI: http://hyperspace.aei.mpg.de/2010/06/18/einstein-toolkit-release/ Additional Information: http://einsteintoolkit.org/ We are pleased to announce the first release (code name "Bohr") of the Einstein Toolkit, an open, community developed software infrastructure for relativistic astrophysics. The Einstein Toolkit is a collection of over 130 software components and tools for simulating and analyzing general relativistic astrophysical systems that builds on numerous software efforts in the numerical relativity community including CactusEinstein, the Whisky hydrodynamics code, and the Carpet AMR infrastructure. The Cactus Framework is used as the underlying computational infrastructure providing large-scale parallelization, general computational components, and a model for collaborative, portable code development. The toolkit includes modules to build complete codes for simulating black hole spacetimes as well as systems governed by relativistic hydrodynamics. Current development in the consortium is targeted at providing additional infrastructure for general relativistic magnetohydrodynamics. The Einstein Toolkit uses a distributed software model and its different modules are developed, distributed, and supported either by the core team of Einstein Toolkit Maintainers, or by individual groups. Where modules are provided by external groups, the Einstein Toolkit Maintainers provide quality control for modules for inclusion in the toolkit and help coordinate support. The Einstein Toolkit Maintainers currently involve postdocs and faculty from five different institutions, and hold weekly meetings that are open for anyone to join in. Guiding principles for the design and implementation of the toolkit include: 1: Open, community-driven software development that encourages the sharing of code across the community, prevents code duplication, and leads to sustainable support and development of essential code. 2: Well thought out and stable interfaces between components that enable multiple implementations of physics capabilities, and allow groups or individuals to concentrate on their areas of interest. 3: Separation of physics software from computational science infrastructure so that new technologies for large scale computing, processor accelerators, or parallel I/O can be easily integrated with science codes. 4: The provision of complete working production codes to provide: prototypes, standard benchmarks, and testcases; codes that are available for and usable by the general astrophysics community; tools for new researchers and groups to enter this field; training and education for a new generation of researchers. For more information about using or contributing to the Einstein Toolkit, or to join the Einstein Toolkit Consortium, please visit our web pages at <http://einsteintoolkit.org>. We thank the numerous people who contributed to this software over the past many years; there are too many to be listed here. We also gratefully acknowledge those who helped in the past months to make this release happen.

He is survived by a wife, son, daughter and grandson who all live in Linköping, Sweden. Brian worked at the Mathematics Department of Linköping University (LiU). He was born in Northern Ireland and had that marvellous broad Northern Ireland accent which people loved to hear. Brian finished his PhD under the supervision of Clive Kilmister (who also sadly died about a month ago). Brian was an ‘Effer’, a name given by and to the PhD students who shared the office at room F of the old building of King's College, on Surrey Street, just above the Aldwych station and the London Roman Bath, from mid 60's to mid 70’s. That was a very rich period for gravitation physics when we lived under the strong influence of Felix Pirani, Hermann Bondi, Roger Penrose, Stephen Hawking, William Bonnor, Clive Kilmister among others. This was a rich period when many new ideas on gravitational physics were being created, mostly on its mathematical aspects. After graduating from Queen’s Belfast, Brian worked in Cameroon and Ghana before his PhD studies and after his PhD exam he went back to work in Ghana. After many years in Ghana he moved to Botswana in 1982. During this time he also in secret supervised a banned ANC activist that later became a South African minister who opened the Durban GR meeting in 2001. He then moved to Linköping in Sweden in 1987, where he and Malcolm Ludvigsen inaugurated and developed the gravitational physics program at LiU. He was the supervisor of several successful PhD students. One of his characteristics was to help the development of applied mathematics programs in developing countries, a passion that was born during his time in Africa. He was working on a program for collaboration between the Swedish and Brazilian applied mathematical programs, but it was beaten by the slow pace of bureaucracy and shortness of life. Brian was a classical relativist, in the sense that his works were mainly motivated by geometrical aspects of Riemann geometry in general relativity. Part of his work was devoted to the field of exact solutions and in particular the GHP formalism and generalisations of it. An important outcome of these studies is the Edgar-Ludwig metrics. In the latter period, motivated by the support of Kilmister, he was working with various collaborators on the problem of Lanczos potentials and dimensionally-dependent identities for general relativity. At the time of his passing he was finishing one of such papers. We will miss his scientific enthusiasm, his willingness to help scientists around the world, and above all his always joyful presence. >From all friends of Brian
