The 19th edition of the Green500 was released today with the usual array of accelerated systems at the top of the list and a plethora of energy-sipping x86 clusters comprising the remainder. For the most part though, energy efficiency gains slowed over the past 12 months after chalking up some pretty impressive gains in previous years.
One of the most popular sessions at last week’s ISC High Performance conference was titled "Scaling Beyond the End of Moore’s Law," which was a series of three talks that delved into some of the technology options that could reanimate computing after CMOS hits the wall sometime in the next decade. The subject’s popularity is unsurprising, given that the supercomputing digerati that attend this event are probably more obsessed with Moore’s two-year cadence of transistor shrinkage than any other group of people on the planet.
There was a time when the only thing that the high performance computing industry paid attention to was FLOPS. Indeed, for most of the history of HPC, floating point operations per second was the one true metric, and only those machines that delivered them in the largest quantities were deemed to be true supercomputers. Performance, after all, is HPC’s middle name.
Cavium has launched its latest ARM server processor, the ThunderX2, a second-generation SoC aimed at the same datacenter workloads that are currently dominated by Intel’s Xeon CPUs. The new chip is designed to go head-to-head with those Xeons, while at the same time get out in front of the 64-bit ARM competition from Applied Micro, Broadcom, and others.
FRANKFURT, Germany; BERKELEY, California; BLACKSBURG, Virginia; May 6 – The ISC Group, promoter of the TOP500 list, is pleased to announce that the Green500 will be integrated with the TOP500 project as of today, hence streamlining all future submissions to be based on joint power submission rules. The integration follows nearly a decade of collaboration and several years of discussions between the two projects as well as with the Energy-Efficient High-Performance Computing (EE HPC) Working Group.
