New release of the NAG Fortran Library now available
NAG is delighted to announce the availability of the latest NAG Fortran Library. Now at its 23rd release, the NAG Fortran Library contains over 1,700 powerful, reliable and flexible algorithms, ready for use from a wide range of operating systems, languages, environments and packages including Excel, Java, MATLAB and .NET/C#. The NAG Library is embedded in thousands of applications that are in use within Fortune 500 companies and is utilized by instructors at prestigious learning institutions around the world because of its unrivalled quality, broad applicability and extensive numerical capabilities.
Over 100 new user-callable routines have been added at this release. More specifically, new and extended functionality has been incorporated into Library chapters on statistics, optimization, wavelet transforms, nonlinear equations, ordinary differential equations, interpolation, surface fitting, matrix operations, linear algebra, and special functions. For example, the already extensive optimization chapters have been extended with new methods, new base generators augment the broad existing range of random number generators; and the interpolation chapter now includes routines for four- and five-dimensional data.
Supported NAG Fortran Library users will receive notification about how to upgrade to the new release as soon as their particular implementations are made available. If you have any questions please email us.
The next releases of the NAG Toolbox for MATLAB and the NAG Library for SMP & Multicore will be available later this year. The next NAG C Library release will be in 2012.
Further information about specific features which are newly available at Mark 23 of the NAG Fortran Library will be presented in future editions of this newsletter.
NAG Optimisation routines now available as an R Package
R is a programming language and software environment for statistical computing and graphics. NAG has now produced a trial version of the optimization Chapter (E04) as an R Package to see if it is of useful to those of you who work in R.
This R package is available from our website. Please let us have your comments and suggestions.
Note: Many NAG routines can be called from R via a 4 step process which is described here.
International Supercomputer Conference 2011
NAG participated in the ISC event this month. (19-23 June 2011. Hamburg)
NAG was involved in the Analyst Crossfire session. The other panellists were from the Tokyo Institute of Technology, HLRS (the High Performance Computing Center in Stuttgart) and Bull. More details can be found at http://www.supercomp.de/isc11_ap/php/HTML/contribution_detail.php?con_id=1406&evid=224&request_day_id=15
NAG also contributed to the session on 'Data?Parallelism/SIMD for HPC' which looked at how to best utilize modern hardware technologies with respect to vectorization and data-parallelism at the level of the core, processor, node and cluster. More details are available at http://www.supercomp.de/isc11_ap/php/HTML/contribution_detail.php?con_id=1464&evid=206&request_day_id=14.
A recording of our latest live webinar, titled ‘NAG, optimization and finance’, has been added to the selection on the webinars resource page

A view of the NAG Library
Read the latest independent review of the NAG Library for .NET on the i-programmer site:
'... the temptation is to always do it yourself. You have the paper that describes the method so why not just implement it from scratch? After all it can't take long as numerical programs are never complicated or run to many lines.
Yes, I have done it myself and well remember the hours of work spent testing and finding the bugs in my principal components (eigenvalue) routine and at the end of the day did I really trust it? '...
NAG and Intel(R) MIC
NAG has been working closely with Intel Corporation on the evaluation of the suitability of Intel® Many Integrated Core (MIC) architecture for advanced numerical computation.
... 'We have been able to produce working NAG routines quickly on the "Knights Ferry" platform’ said Mike Dewar, the Chief Technical Officer for NAG. ‘It certainly seems that this architecture will be very attractive to users...'

C++ and using Object fields with NAG Library for .NET
Recently, we had a question from a user of the NAG Library for .NET. He wondered whether it was possible to use methods from objects rather than static methods as callback parameters to the NAG methods. The library was designed to do this, but there are not many examples of this in the documentation. In addition, the user was coding in C++/CLR and we currently have no examples of using the library in this environment. To see how to use object fields when invoking NAG methods from within C++/CLR (though the results can be translated to other environments), take a look at http://blog.nag.com/
Training courses available for CUDA and OpenCL
NAG now runs two new GPU Programming Courses:
An introduction to the development of CUDA programs for NVIDIA GPUs.
An introduction to writing OpenCL programs for GPU and multicore CPUs.
