nVIDIA GPU workshop

General-Purpose Graphics Processing Units are changing the landscape of high performance computing, with the current number one theoretical peak performance supercomputer Nebulae based GPUs. On October 26th you will have the opportunity to hear about the abilities of GPUs for high performance computing, directly from two of the nVIDIA researchers: Chris Butler and Timothy Lanfear. This workshop will include both an introduction to the architecture and capabilities of the new Tesla series GPUs, as well as exemplar applications.

PhD Studentship at Heriot-Watt University

This PhD project involves the development and analysis of approximate methods for partial and stochastic differential equations, along with the linear algebra needed to make them work efficiently. The goal is to develop highly efficient numerical algorithms suitable for modern high performance computers, from the now commonplace desktop dual and quad-core computers, through the upcoming multi-core desktop machines and on to high-end national research laboratory scale computers. The equations arise in the modelling of real-world problems (e.g. in the energy sector, medicine and biology) and the project will involve interactions with the end-users.The studentship is provided by Heriot-Watt University in support of the NAIS project.

We offer a lively, supportive and highly research-active environment for graduate students in Mathematics at Heriot-Watt, embedded in the Maxwell Institute for Mathematical Sciences partnership with the University of Edinburgh as well as the NAIS project. Students with a good first degree or MSc in mathematics with knowledge of numerical analysis, differential equations and some analysis would be ideal. Training is available in numerical analysis and in high performance computing.

EPCC wins grant for Asynchronous Algorithms in EPSRC HPC Algorithms Sandpit

A grant was awarded following the EPSRC HPC Algorithms Sandpit to a team from the Universities of Manchester, Leeds, Edinburgh, Hull and Strathclyde. Dr Mark Bull from NAIS partner EPCC will lead the Edinburgh part of the project. Summary: The project aims to enable a step change in the performance of a wide range of real world applications, by applying and improving existing asynchronous algorithms for large sparse systems, and developing and analyzing entirely new asynchronous algorithms. The project will develop prototype software implementations of these algorithms which demonstrate both scalability and reliability. In the implementation of the software we will address the diversity of hardware platforms and programming models which will be found in future generations of machines, with at least 1 million cores. Another key aspect will be to exploit the inherent fault-tolerant nature of asynchronous algorithms to help address the need to cope with frequent hardware failures in extremely large machines. The software will be integrated into our two exemplar applications (bone modelling and power grid management), enabling them to carry out entirely new science as a result of enhanced problem resolution and reduced time to solution.

NAIS Joins the European Exascale Software Initiative

Andreas Grothey (Edinburgh-Mathematics) will act as deputy to Iain Duff (Rutherford Appleton Lab) on the European Exascale Software Initiative, organised by a consortium of European leaders in HPC. The main goal of EESI is to build a European vision and a roadmap to address the challenge of Peta and Exascaling computation and simulation. This will be done by involving large numbers of European actors in the HPC sphere, investigating how Europe is located in the overall international HPC landscape and competition, its strengths and weaknesses, and the topics and challenges that Europe may and must develop. EESI will also identify the sources of competitiveness for Europe induced by the development of Peta/Exascale solutions and usage.

Multiscale Molecular Modelling conference receives E-Science Institute Co-Funding

NAIS has received matching funds from the UK's e-Science Institute and the EPSRC-funded Research Network on Mathematical Challenges of Molecular Dynamics (MD-NET) to run an international meeting June 30-July 3, 2010. From the overview of the meeting: "...As uniprocessor performance increases tail off, the search is on for new types of (molecular modelling) methods that can continue to offer speed increases in the setting of distributed hybrid architectures, or the grid. An interesting recent development which is becoming prominent in the molecular simulation literature is the reformulation of molecular modelling in terms of path sampling strategies, whereby multiple trajectories are used to probe complex configurational pathways, often disturbing thermodynamic equilibrium to enhance mobility or to force rare transitions. These multiscale molecular algorithms are well suited to implementation in an event-driven distributed computing setting... "
