NAG and Cloudera: How to call NAG Library routines from Cloudera using Spark
Cloudera is a software company that provides Apache Hadoop-based software, support and services, and training to business customers.
Cloudera's open-source Apache Hadoop distribution targets enterprise-class deployments of that technology. Cloudera also donates engineering output upstream to the various Apache-licensed open source projects (Apache Hive, Apache Avro, Apache HBase and so on) that combine to form the Hadoop platform. Cloudera is also a sponsor of the Apache Software Foundation.
NAG Library algorithms can be called from Cloudera to enhance the accuracy and speed of processing for a range of problem types.
NAG are also able to provide advice about the most appropriate approach, using NAG routines or others, to solving numerical problems in a Cloudera Hadoop environment.

Particle physics application uses the NAG Fortran Compiler to produce correct code more quickly and efficiently
WHIZARD is an easy-to-use tool for particle physics simulations that uses many modern programming features of the standards Fortran2003 and Fortran2008. The WHIZARD team is currently mainly located at three places: the DESY research center in Hamburg, the University of Siegen and the University of Würzburg.
WHIZARD is under continuous development. The application's calculations have to keep up with the contemporary state of the theory, increasing the accuracy of WHIZARD's predictions, and the application has to be adapted to users' changing requirements. The extensive testing and debugging ensures that WHIZARD can be used smoothly by its global user base.
For this ongoing work, the WHIZARD developers make full use of the NAG Fortran Compiler, renowned for its excellent checking capabilities. The NAG Compiler builds the code in a significantly shorter amount of time than other compilers, enabling much quicker development and debugging cycles. Memory leaks have been identified using the Compiler traceback facility, to reduce WHIZARD'S memory usage, and code quality is enhanced further by referring to the Compiler's detailed error messages, both during build and run-time.
Christian Weiss, a member of the WHIZARD development group, said: "By using the NAG Fortran Compiler in the development and ongoing use of the WHIZARD application we see two key tangible benefits. The first is the improvement in the quality of the code which is imperative for the portability of the application and the accuracy of WHIZARD's computational results. The second is the substantial reduction in development time which probably saved me one or two months of my PhD time."

TakeAIM: Highlighting the importance of mathematics in our everyday lives
Organised by the Smith Institute for Industrial Mathematics and System Engineering, the goal of the TakeAIM competition is to make visible the crucial role that mathematics plays and will increasingly play in all aspects of our lives. NAG is delighted once again, to sponsor this highly worthwhile competition.
The mathematical sciences will have ever greater influence on shaping how we interact with friends, colleagues and neighbours, on the goods and services that we use, on how we maintain our health, how we travel and how we consume natural resources.
Whatever these innovations are, they will be underpinned by mathematics. Research in mathematical sciences is happening right now and will be crucial to our future economy and social well-being. Rapid advances in capacity for computing and data handling are creating opportunities that can be exploited through the imagination and insights of mathematical scientists. Their work will build upon the stunning successes of mathematics in understanding and predicting the behaviour of physical, biological, and social systems.
The TakeAIM competition highlights some of the areas where new thinking is coming over the horizon, with influence far outside the academic world. It enables young researchers to express in their own words and for a general audience the potential future impact of their work.

Fortran Modernisation Workshop - An Attendee's Perspective
Jonathan Cooper, Research Lecturer, Department of Computer Science at The University of Oxford recently attended a Fortran Modernisation Workshop and has posted about the day:
This two day intense workshop covered a vast array of topics related to developing reliable computational science software in Fortran more effectively, yet still retained time for practical work trying these out and discussions between the course leaders and participants. It was attended by 31 students and staff members of the University. Wadud Miah (NAG) led the workshop, assisted in lecturing by Fatima Chami (Durham) and Kyle Fernandes (Cambridge).

Mesh Generation in the NAG Library
Mesh generation is essential when using the finite element method to solve a system of partial differential equation (PDE). PDEs, where this method is appropriate, can be used, for example, to solve problems in solid mechanics, fluid mechanics and thermal modelling. Using a meshing algorithm is indispensable when the geometry of the numerical domain is not trivial, i.e. not rectangular. Meshing ensures that the spatial discretization of the domain reflects the geometry of the numerical domain. Read the blog here.
