The new Green500 list of the most energy-efficient supercomputers demonstrates some significant progress from last year. Thanks to the new manycore processors from Intel and NVIDIA that are starting to penetrate the top systems, performance per watt numbers are on the rise.
The Texas Advanced Computing Center in Austin has installed the world’s largest solar-powered HPC system. The 400 teraflop supercomputer, known as Hikari, is an HPE Apollo 800 cluster that uses technology supplied by Japanese green energy specialist NTT FACILITIES. In addition to taking advantage of Austin’s abundant sunshine, the power setup also employs high voltage direct power (HVDC) to further reduce energy consumption.
Aquila, a system provider based in Albuquerque, New Mexico, has unveiled a new liquid-cooled server platform that offers one of the densest and most energy-efficient architectures in the market. The platform, known as Aquarius, uses a patented warm water cooling technology along with rack-level power distribution to minimize energy consumption and allow for very high levels of computational density.
The prospects for another serious rival to the x86 processor in the high performance computing space are looking much better this week after ARM Holdings presented the company’s plan to offer an HPC version of its 64-bit architecture. Known as ARMv8-A SVE, the design incorporates a technology known as the Scalable Vector Extension (SVE), which will provide a unique type of flexibility with regard to vector processing -- the basis of many scientific and engineering workloads.
