NAG at the core of ARM Performance Libraries

At the recent supercomputing conference in Austin, ARM announced new math libraries that are precision-tuned for 64-bit ARM®v8-A processors. At the core of the ARM Performance Libraries is the NAG Library and associated validation suite. The NAG Library represents a tried and trusted baseline from which to build variants designed for the ARMv8-A architecture. Building on NAG's industry-tested BLAS, LAPACK and FFT math routines enables ARM to bring mature, accurate and validated core libraries to market quickly.

"Utilizing NAG's Linear Algebra and FFT algorithms at its core, ARM Performance Libraries are the perfect building block for higher-level scientific computing applications," said Mike Dewar, CTO, NAG. "The hardware-specific performance tuning enabled by ARM Performance Libraries, combined with NAG's stringent requirements for robustness and mathematical correctness, will yield the fastest and most accurate computational mathematics routines for the ARM ecosystem."

Meet the user: Luke Pitt, University of Manchester NEW

The winner of a recent NAG prize, Luke Pitt, PhD Student at the School of Electric and Electronic Engineering at the University of Manchester, told us about his use of the NAG Library in his work, he wrote:

My PhD project involves the design, construction and deployments of a sensor network for monitoring the internal environment in relation to thermal comfort together with the subsequent analysis of the data collected by it. The sensor network consists of 17 sensor nodes deployed in both conventional offices and open plan workspace. The network measures a number of environmental parameters every 30 seconds as well as providing a simple physical interface for occupants to express their current level of satisfaction with the thermal environment. The network has been collecting data since September 2012.

As part of the data analysis of the collected data I used the NAG Library to perform principal component analysis on a total of 256 variables measured by the nodes, a local meteorological station and the building's fiscal energy meters. I chose the NAG Library to be confident that I was using a reliable and well tested implementation of the algorithm that would work with the size of the dataset I was analysing.

Performance Optimisation and Productivity

NAG are delighted to be part of a new EU group whose principal aim is to improve the performance of applications running on high performance computers - a task that NAG has years of experience at achieving.

Performance Optimisation and Productivity, or POP for short, launched in 2015 and is coordinated by the Barcelona Supercomputing Center. POP's project partners include, NAG, the Jülich and Stuttgart Supercomputing Centers, the University of Aachen, and Ter@atec.

POP is one of eight Centers of Excellence in HPC that have been promoted by the European Commission to foster the use of HPC technologies in science and engineering. If you'd like to learn more about POP contact

Diversity at NAG - vision for our future and where we are today (Katie O'Hare)

A short time ago my colleague, Andrew Jones, VP HPC Business, introduced me to John West, Director of Strategic Initiatives at the Texas Advanced Computing Center (TACC). Andrew found John's blog posts "Diversity in HPC Won't Improve Until We Start Counting" and "How One HPC Center Learned to Count" inspiring and suggested NAG get involved. Read more

Finding the safe path through the HPC fog

The use of HPC (or supercomputing or big data computing or advanced technical computing or …) delivers real and significant benefits to those organizations that can exploit it effectively. However, the world of HPC technology is a complex space, with a plethora of technology options, continuous rapid change, ambiguous long terms trends, diverse business models, and potential disruptive technologies.
