Power/Performance Bits: Aug. 30

Scalable data center chip Princeton University researchers designed a new scalable chip specifically for data centers and massive computing systems. The team believes the chip, called Piton, can substantially increase processing speed while slashing energy needs. The chip architecture is scalable; designs can be built that go from a dozen cores to several thousand. Also, the architecture ... » read more

China Tops Top500

The last time I wrote about the Green500, the Chinese machine Tianhe-2 was at the top of the Top500 list. At that point, Tianhe-2 had slipped from 49th to 64th on the Green500. Tianhe-2 has now slipped to second place on the Top500, only surpassed by yet another new Chinese machine, NRCPC’s Sunway TaihuLight. There has also been some consolidation between the Top500 and the Green500 lists: it... » read more

New Machine Tops The Green500 List

The Green500 has released its latest list of the top 500 most energy efficient Supercomputers and there is a new machine, L-CSC from the Helmholtz Center that is the first supercomputer to surpass the 5 GigaFLOPS/watt barrier. The machine is yet another heterogeneous system and is based on AMD FirePro S9150 GPU accelerators and Intel Xeon E5-2690v2 10C 3GHz processors. IBM and NVIDIA aren’... » read more

Shaking Up The Green500

Barry Pangrle Last September, I wrote about the efficiency of IBM’s Power7+ architecture in my blog. IBM’s Sequoia supercomputer (a BlueGene/Q system) this past June had just shot to the top of the Supercomputing Top500 chart, clocking in at 16.32 petaflop/s on the Linpack benchmark. Other systems built around the IBM BlueGene/Q, Power BQC 16C 1.60GHz, Custom were also dominating the top o... » read more
