Wojciech Rozowski at last month’s Science: Polish Perspective 2018 conference

First year Computer Science student Wojciech Rozowski from the University of Southampton has devised a new synchronisation element for high-performance computing that can optimise access to shared data.

The innovation, which draws upon his studies of experimental hardware technology that started as a high school hobby, can improve the performance of operating systems on multi-core computers.

Wojciech presented the findings at last month’s Science: Polish Perspective 2018 conference at the University of Oxford, alongside hundreds of renowned Polish scientists.

The BSc Computer Science student has tapped into the potential of hardware transactional synchronisation extensions (TSX) technology, which has been shown to guarantee an up to 41% increase in performance of handling critical data.

“The efficiency of multi-core processors isn’t in linear relationship with the number of its cores,” Wojciech explains. “The increased number of cores is accompanied by the occurrence of more data conflicts. As a result of this study, a new synchronisation element has been created which combines TSX and spinlocks in such a way that it guarantees error-free handling of all critical data and it uses transactional memory optimisations wherever possible.”

Wojciech presented an early version of this project at Intel International Science and Engineering Fair in Phoenix, USA, the world’s largest and most prestigious science fair for pre-university students. His work was acclaimed by academics and placed 4th for the Systems Software and Special Award from the Association for Computing Machinery.

“Developing this project has been an extremely interesting and fun experience for me and a great opportunity to learn new things in areas of parallel computing and computer systems,” Wojciech says. “My ultimate dream would be to write a scientific journal publication about this research. However, to do so I know that I must next improve my testing methods in such a way to get reliable data covering a broader range of test cases.” Wojciech has performed a series of benchmarking tests which proved the technology optimises data access in certain cases and his new synchronisation element has been successfully implemented into the Unix operating system, a popular platform for high-performance computing.

Abstract: High voltage systems are being increasingly used in aircraft such as the Boeing 787 and the Airbus A350 to support the electrification of energy on board, allowing the removal of pneumatic and hydraulic systems. The operation of high voltage systems in an aerospace environment introduces a number of specific issues relating to the pressure and temperatures that the aircraft see during the flight cycle. This talk will highlight the key challenges involved in the development of future aerospace high voltage systems.

Dr David Flynn is to receive a prestigious medal from the Institute for Electrical and Electronics Engineers (IEEE)

Visiting Professor Dr David Flynn has been honoured for the exceptional impact of his career with a prestigious medal from the Institute for Electrical and Electronics Engineers (IEEE).

The co-director of the Arm-ECS Research Centre, an award-winning research collaboration between Arm and the University of Southampton, has been named a co-recipient of the IEEE and Royal Society of Edinburgh (RSE) 2019 James Clerk Maxwell Medal.

The honour recognises ground-breaking contributions in the development of electronics and electrical engineering, or related fields.

Dr Flynn has served as a Visiting Professor in Southampton’s School of Electronics and Computer Science for the past decade and has nurtured a strong partnership between the University and his employer, Arm. The Arm-ECS Research Centre advances future mobile and embedded systems and was recently shortlisted for Research Collaboration of the Year at the 2018 TechWorks Awards.

The IEEE/RSE James Clerk Maxwell Medal was established in 2006 and is named in honour of the 19th century Scottish mathematician and physicist who laid the foundations of electromagnetic wave theory and radio communications. Dr Flynn will share the honour with former Arm Fellow David Jaggar, with their award citation commending their ‘contributions to the development of novel Reduced Instruction Set Computer (RISC) architectures adopted in over 100 billion microprocessors worldwide’.

Dr Flynn said: “As engineering practitioners it is with surprise and delight that David and I accept such a prestigious award and reflect back on the computer scientists and electronics engineers, educators and creative business partnership visionaries that inspired us in our early work at Advanced RISC Machines/ARM Ltd.”

Dr Flynn is a Director of Technology at Arm in Cambridge and a senior member of the IEEE. He is attached to Southampton’s Centre for Internet of Things and Pervasive Systems and regularly provides industrial oversight for postgraduate research. Under his direction with Southampton’s Professor Bashir Al-Hashimi, the Arm-ECS Research Centre has focussed on advanced design methods, architectures and their practical validations for energy-efficient and dependable single-core and multi-core processor systems.

To date, the Centre’s projects have fabricated 12 new test chips, released three open source tools, collaborated on co-authoring 32 papers, graduated six co-supervised PhD students and completed 22 internships in Cambridge.
