energy-aware high-performance computing

Research highlights the future of energy-aware high-performance computing

Leipzig, June 18, 2014. As reported in Inside HPC.

With energy costs a growing concern for High Performance Computing, Allinea Software will demonstrate its vision of a greener future with a preview of new tool extensions for application energy usage optimization at this year's International Supercomputing Conference (ISC'14) in Leipzig.

With larger numbers of data centers consuming over 1MW of power or having electricity bills topping $1M, energy is focussing the minds of the system sponsors and managers, says David Lecomber, CEO of Allinea Software.

Allinea Software worked with application performance experts at the University of Warwick to investigate novel energy and power measuring techniques for scientific application workloads.

Energy usage data is increasingly available at the system level, and our research also explored proxies for energy such as hardware counters to see where they could give deeper insight, said Professor Stephen Jarvis of University of Warwick’s HPC Performance Analysis Group.

The research supported the view that in many cases applications can reduce energy costs without adversely impacting actual run time.

Improving the green credentials of hardware and data centers is vital, and progress is good, but applications must also play their part. Energy optimization is a natural fit for our performance tools, adds Lecomber.

With the variety of workloads that HPC centers have, a ‘one size fits all’ strategy is a costly error – and so Allinea Performance Reports will provide information for application users and system managers to enable them to tune system and application parameters such as CPU frequency for optimal energy use for each application.

Our developer-centric tool, Allinea MAP, will allow scientific code developers to focus energy optimization down into the source code – making changes to the application to drive faster performance and lower energy consumption at the same time.

This research has been supported by the Technology Strategy Board's Emerging Technologies Energy Efficient Computing Programme.

DCS Student Leads Workshop at Scratch@MIT 2012

Philip How, a recent graduate in MEng Computer Science, has returned to the United Kingdom after developing and leading a successful workshop at Scratch@MIT 2012. As well as marking the end of his undergraduate degree, Philip's role in this exceptionally popular event represents the culmination of a long-standing involvement with Warwick Technology Volunteers, a dedicated groups of technically minded students and staff members who make a significant contribution to the local community through involvement with schools.

Scratch@MIT is the biennial conference where educators, researchers and developers gather on the MIT campus in Cambridge, Massachusetts to share their experiences and imagine the possibilities of Scratch. The workshop that Philip led, entitled Sensing Our World, involved participants building a variety of sensors, ranging from simple sensors that relied on the conductivity of pencil tracks to working touchpads made from CD cases.

On his involvment, Philip is quick to acknowledge the contributions of those around him, noting that "The staff and students contributing to Warwick Technology Volunteers are fantastic. We couldn't have hoped to achieve what we have without the hard work and comittment of the team of staff and students involved, particuler Margaret Low. In my time here she's an fantastic at organising the efforts of students and liasing with local schools".

DCS Celebrates Alan Turing's Centenary

Ben Sach

Wednesday 20th June saw the Department of Computer Science (DCS) host a celebration of the centenary of the birth of Alan Turing, a pioneer in Mathematics who is widely considered to be the founding father of Computer Science.

The event was well attended by both staff and students alike, with many undergraduates making the most of being free from exams. The highlight of the day were the talks, by three academics from DCS.

Martin Campbell-Kelly opened the day talking about the ACE, a computer designed by Turing that was at the heart of the British computer industry. The talk highlighted the relationship between Britain and America in the days before the founding of Computer Science as we know it, and provided an interesting perspective on the part Turing played in the development of the modern computer.

Following this bright start to the day, Sara Kalvala delivered a riveting talk on Turing's last published work - his theory of morphogenesis. Turing's theory provides an insight as to how cells that are identical can divide into the diverse range of cells that make up natural life. Sara also highlighted a recent paper that is thought to prove this theorem, going on to show how the popular press turned it into a theory of how tigers get their stripes!

After lunch, Ben Sach concluded the day with a closer look at Turing's personal life. Beginning with Turing's early life, including his infamous 60 mile cycle to Sherbourne school, Ben's talk followed Turing's life through Cambridge, to Bletchley Park, and finally to Manchester University. This more intimate view of Turing, often told through extracts written by those who knew him best, provided a fitting end to the day of celebration by highlighting Turing's eccentric, yet charming nature.
