DailyTech reports The Barcelona Supercomputer Center (BSC) is working on Mont-Blanc, a new supercomputer that will start NVIDIA's Tegra 3 SoC along with anywhere from 2,000 to 4,000 processors. The design aims to become world's most power efficient supercomputer, Mont-Blanc targets 7 gigaflops per Watt, over three times as much as the IBM Blue Gene's 2 gigaflops per Watt.
But Mr. Ramirez's team is far from finished when they complete the lightweight design sometime in the next couple years. They're already planning its successor, a next generation design, which will be build on NVIDIA's 64-bit ARMv8 instruction set Stark series (or possibly a later variant).
That 64-bit design is aimed at becoming the world's most powerful supercomputer, with a planned processing power of 200 petaflops (twenty times the K Computer's capacity). That design will be completed in 2017 (approximately), according to plans shared with Wired.
