CCP2 Information Quarterly

The first issue of the Information Quarterly was edited and published by DW Norcross (Joint Institute for Laboratory Astrophysics, University of Colorado, USA) on 15 January 1976.

It was created with the idea of becoming "a very useful tool for keeping track of the developments, both in software and production, for the large set of computer programs, developed primarily at U.C.L."

The newsletter was eventually taken over by CCP2 and continued as a means of informing the community on software developments. This function is now carried out via the WWW.

CCP2 News: Winter 2008

We would like to publicize a meeting to take place at Queen's University, Belfast on 15-16 January 2009: 3rd MRS Network Workshop - Numerical Accuracy and Reliability .

The Multi-core Reconfigurable Supercomputing network (MRS) is an EPSRC initiative funded under EPSRC's Digital Economy programme. The aim of MRS is to promote the use of FPGAs, many-core GPUs and other accelerators for scientific computation in a range of application areas within EPSRC's Digital Economy programme.

The 3rd workshop will be on the topic of accuracy and reliability in scientific computation. Through a series of invited talks and hands-on tutorials leading experts will illustrate the pitfalls of numerical computation, describe tools (INTLAB and CADNA) that can be used to assess the accuracy and reliability of existing scientific software, and present techniques to improve the accuracy and reliability of new scientific software. Speakers include: Nick Higham FRS (University of Manchester), Jack Dongarra (University of Tennessee/ORNL), Jean-Marie Chesneaux (LIP6, Paris), Siegfried Rump (Institute for Reliable Computing, Hamburg University of Technology), Mike Giles (University of Oxford) and George Constantinides (Imperial College London). Details are available here.

We would like to publicize a meeting to take place at UCL on 14-15 April 2008: Atoms and Astrophysics: Mike Seaton's Legacy.

Professor Mike Seaton, who died in May last year, was an outstanding atomic and astrophysicist, with wide-ranging research interests. At this meeting, many of his friends, collaborators and students will give talks on subjects relevant to Mike's work. Topics will include quantum defect theory in atoms and molecules, electron-ion scattering theory and computation, nebular astrophysics and stellar opacities.

The meeting will start at 10am on April 14th and end at 4.00pm on April 15th, 2008. The programme will consist mainly of invited talks but there is also some space for contributed talks. Confirmed speakers include: Professor Nigel Badnell, Professor Mike Barlow, Professor Phil Burke, Professor Keith Butler, Dr. Franck Delahaye, Professor Gary Ferland, Professor Chris Greene, Dr. Christian Jungen, Professor Ian Percival. Further information can be found at the meeting website.

CCP2 News: December 2007

This booklet contains articles contributed by speakers at the succesful 13 - 15 September UCL Workshop and is available free of charge: please contact Christine Johnston with a clear and complete postal address. Please click here for the contents list. The booklet is also available as a pdf file.

CCP2 News: August 2007

Details of speakers and talks are now available for the international CCP2 workshop on Mathematical and Computational Methods in R-matrix Theory at University College London, UK, 13 - 15 September 2007. The workshop programme is now available. The workshop follows the QuAMP IV conference at UCL (see also this link).

We would like to publicize a workshop on "Solving the Bogoliubov-de Gennes and Gross-Pitaevskii equations for superconductors, superfluids and BEC" to be held at the Britannia Hotel, Manchester, 28-30 September 2007.

CCP2 News: June 2007

We announce the forthcoming international CCP2 workshop on Mathematical and Computational Methods in R-matrix Theory at University College London, UK, 13 - 15 September 2007. The workshop follows the QuAMP IV conference at UCL (see also this link).

An 18-month Post-Doctoral Research Fellowship is available at Queen's University Belfast from 1 October 2007 to assist in the development, object-oriented re-engineering, and numerical validation of the Fortran code 2DRMP. Developed at Queen's University Belfast, this numerical code is intended to enable virtual experiments to be performed on electron collisions with hydrogen and quasi one-electron atoms and ions using high performance computers. For details please click here (closing date: 4.00 pm Friday 22 June 2007).

CCP2 News: May 2007

We would like to publicize an interdisciplinary STFC/UCL meeting on theoretical approaches to the dynamics of many electron systems in strong laser fields to take place at Daresbury Laboratory on 12 June 2007 (to secure lunch, please register by 11.00am, 5 June).

Many congratulations to Stan Scott and Penny Scott (Queen's University, Belfast), Liviu Ixaru (Horia Hulubei National Institute of Physics and Nuclear Engineering POB MG-6, Bucharest) and Christophe Denis (University Pierre et Marie Curie-Paris 6) on being awarded the UK Research Councils' HEC Strategy Committee HPC Prize 2006 for machine utilization, for work on the fast computation of Slater integrals. The research was focused on improving a suite of two-dimensional R-matrix propagation programs aimed at creating virtual experiments on HPC and Grid architectures to study electron scattering from H-like atoms and ions at intermediate energies. The resulting algorithms are embodied in a new computational strategy that is more accurate and is between one and two orders of magnitude faster than the original implementation. By further exploiting parallelism on HPCx the resulting implementation is up to 350 times faster than the original and 25 times less costly.

Following the successful April 2006 CCP2 workshop on explicitly correlated wavefunctions, we would like to remind readers that a book of conference proceedings is available. Please contact Christine Johnston (christine.johnston@ucl.ac.uk) with a clear and complete postal address for a free copy. Please click here for the contents list. The book is also available as a pdf file.

SUPERCOMPUTING RESOURCES ACROSS EUROPE AVAILABLE TO UK RESEARCHERS

The DEISA project is a consortium of major national HPC centres which operates an integrated infrastructure over eleven existing national high-end platforms across Europe. UK resource HPCx has recently joined the DEISA supercomputing Grid. DEISA (Distributed European Infrastructure for Supercomputing Applications) is funded by the EU and has access to a large amount of CPU time on these systems - on HPCx, for example, 5% of the total time is reserved for this. All this time is available for researchers to use. You can apply for this time under the DEISA Extreme Computing Initiative (DECI). Under the first call for proposals, projects were accepted with individual CPU requirements of up to several hundreds of thousands of CPU hours. The deadline for the second call is July 15th 2006. This could be a major benefit for researchers in the UK, and HPCx would like to encourage you to take advantage of this opportunity. For details on how to apply see http://www.deisa.eu/applications. If you would like help or advice in preparing your proposal, please feel free to contact the HPCx Support Team support@hpcx.ac.uk.
