Informatics Research Institute (IRIS) September 2008 newsletter
2007-8 was a very busy year for IRIS. It was a bumper year for visiting Profs with Prof Michael Myers visiting from New Zealand, Prof Brian Fitzgerald visiting from University of Limerick, Ireland, Prof. Uzay Kaymak visiting from Erasmus University Netherlands and Prof Steve
Sawyer visiting from Pennsylvania State University, USA. Their visits enriched our doctoral school, seminar programme workshops and our research. We were very lucky to have such a distinguished line up of visiting professors and we offer them hearty thanks and hope to keep
ongoing research links with them
The education of Walter Kohn and the creation of density functional theory
The theoretical solid-state physicist Walter Kohn was awarded one-half of the
1998 Nobel Prize in Chemistry for his mid-1960's creation of an approach to the
many-particle problem in quantum mechanics called density functional theory
(DFT). In its exact form, DFT establishes that the total charge density of any
system of electrons and nuclei provides all the information needed for a
complete description of that system. This was a breakthrough for the study of
atoms, molecules, gases, liquids, and solids. Before DFT, it was thought that
only the vastly more complicated many-electron wave function was needed for a
complete description of such systems. Today, fifty years after its
introduction, DFT (in one of its approximate forms) is the method of choice
used by most scientists to calculate the physical properties of materials of
all kinds. In this paper, I present a biographical essay of Kohn's educational
experiences and professional career up to and including the creation of DFT
Exploring emerging technologies for extreme scale HPC architectures
While architectures and programming models have remained relatively stable for almost two decades, new architectural features, such as heterogeneous processing, nonvolatile memory, and optical interconnection networks, will demand that software systems and applications be redesigned so that they expose massive amounts of hierarchical parallelism, carefully orchestrate data movement, and balance concerns over performance, power, and resiliency. This instability has led to two inevitable problems: decreased programmer productivity, and difficult performance prediction. In this talk, I will describe two solutions to these problems, respectively: our OpenARC compiler and runtime system, and our Aspen performance modeling language. First, OpenARC is a research compiler that supports OpenACC and OpenMP4, and can generate code in CUDA, OpenCL, and LLVM IR. OpenARC has enabled us to explore how to enable performance portability of applications across diverse architectures. Second, Aspen is a domain specific language for structured analytical modeling of applications and architectures. It is designed to enable rapid exploration of new algorithm and architectures. Once created, Aspen models can then be used for a variety of purposes including predicting performance of future applications, evaluating system architectures, informing runtime scheduling decisions, and identifying system anomalies
Informatics Research Institute (IRIS) July 2004 newsletter
This summer period has been rich in presence and dissemination related activities. Several important
conferences, which have enjoyed a great international
participation and success, have been organized by IRIS
academics in Salford. These include NLDB04, CRIS 2004 and the LTSN workshop. Also, a substantial number of research projects have been secured from national as well as European funding sources. All these activities are contributing to reinforcing the leading position that IRIS is currently enjoying in the field of Informatics. This newsletter gives an overview of all research activities
that took place during this reporting period. It is hoped that this will help trigger further collaboration with existing and future colleagues from academia, research and industry to work together towards addressing the many societal and technological challenges engendered by the information age
History of Spin and Statistics
These lectures were given in the framework of the ``Dixi\`eme s\'eminaire
rhodanien de physique'' entitled ``Le spin en physique'', given at Villa
Gualino, Turin, March 2002. We have shown how the difficulties of
interpretation of atomic spectra led to the Pauli exclusion principle and to
the notion of spin, and then described the following steps: the Pauli spin with
22 matrices after the birth of "new" quantum mechanics, the Dirac
equation and the magnetic moment of the electron, the spins and magnetic
moments of other particles, proton, neutron and hyperons. Finally, we show the
crucial role of statistics in the stability of the world.Comment: latex file, 7 figures, 3 table
