GPUs Dominate (Again) The Green500 List


The Green500 has released its latest list of the top 500 most energy-efficient Supercomputers. The top 17 are heterogeneous systems (systems that use more than one type of processor), with the top 15 systems all using NVIDIA Kepler K20 GPUs paired with Intel Xeon CPUs. Still at the top of the list is the Tokyo Institute of Technology GSIC Center’s TSUBAME-KFC, an oil-cooled Kepler powered ... » read more

Manufacturing Bits: Jan. 14


MoS2 FETs Two-dimensional materials are gaining steam in the R&D labs. The 2D materials include graphene, boron nitride (BN) and the transition-metal dichalcogenides (TMDs). One TMD, molybdenum diselenide (MoS2), is an attractive material for use in future field-effect transistors (FETs). MoS2 has several properties, including a non-zero band gap, atomic scale thickness and pristine int... » 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
