PEZY Computing from Japan has earned the top three rankings on the Green500 list, using a 3M Fluorinert Electronic Liquid in an immersive cooling system built by ExaScaler Inc. The Green500 is a biannual ranking of the most energy-efficient supercomputers in the world. The triple win indicates growing progress and adoption in the field of immersion cooling with engineered dielectric fluids and its potential to transform the high performance computing (HPC) industry with step-change improvements in energy efficiency and compute performance.
“Supercomputing should be available for everyone who wants it. With that mission in mind, a team of engineers created Parallella, an 18-core supercomputer that’s a little bigger than a credit card. Parallella is open source hardware; the circuit diagrams are on GitHub and the machine runs Linux. Icing on the cake: Parallella is the most energy efficient computer on the planet, and you can buy one for a hundred bucks. Why does parallel computing matter? How can developers use parallel computing to deliver better results for clients? Let’s explore these questions together.”
“SUPER builds on past successes and now includes research into performance auto-tuning, energy efficiency, resilience, multi-objective optimization, and end-to-end tool integration. Leading the project dovetails neatly with Oliker’s research interests, which include optimization of scientific methods on emerging multi-core systems, ultra-efficient designs of domain-optimized computational platforms and performance evaluation of extreme-scale applications on leading supercomputers.”
“The range of cooling options now available is testimony to engineering ingenuity. HPC centers can choose between air, oil, dielectric fluid, or water as the heat-transfer medium. Opting for something other than air means that single or two-phase flow could be available, opening up the possibilities of convective or evaporative cooling and thus saving the cost of pumping the fluid round the system.”
In this special guest feature, Tom Wilkie from Scientific Computing World writes that software approaches to energy efficiency in HPC may yield unexpected improvements in the hardware of next-generation mobile phone networks. “Adept, a European research project addressing the energy-efficient use of parallel technologies, is expected to release a set of benchmarks that it has developed to characterize the energy consumption of programming models on different architectures.”
