Green Computing: GPUs Strike Back
By Barry Pangrle - 19 Dec, 2016 - Comments: 1

After the last Platform for Advanced Scientific Computing Conference in June, I wrote an article here about how the custom designed chips from NRCPC (used in the Sunway TaihuLight) and PEZY Computing (used in the PEZY Shoubu) had jumped to the top of the Green500 list with the Sunway TaihuLight also remarkably topping the Top500 list. Well, six months after the report from the IEEE/ACM SC16 Con... » read more

China Tops Top500
By Barry Pangrle - 14 Jul, 2016 - Comments: 0

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
By Barry Pangrle - 10 Dec, 2014 - Comments: 0

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

GPUs Dominate (Again) The Green500 List
By Barry Pangrle - 16 Jul, 2014 - Comments: 0

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

Blog Review: Dec. 11

Synopsys’ Brent Gregory has developed a career growth checklist for computer science majors. They should hang this in the hallway at universities. Cadence’s Brian Fuller interviews Saar Drimer, a UK hardware engineer who has been experimenting with odd-shaped PCBs. According to Drimer, 45-degree angles aren’t always optimal. But what happens to all the expensive tools everyone has bee... » read more

Fastest Computers On The Planet
By Barry Pangrle - 05 Dec, 2013 - Comments: 0

The latest Green500 list (Excel spreadsheet here) was just released at the end of last month and heterogeneous systems now own the top of the list. The Top 10 systems all use a combination of Intel Xeon (mostly E5) processors paired with NVIDIA K20s. There are now 6 systems listed that have broken the 3,000 MFLOPS/W barrier and TSUBAME-KFC, belonging to the Tokyo Institute of Technology’s GSI... » read more

The Green500 And The Charge Towards Exascale Computing
By Barry Pangrle - 11 Jul, 2013 - Comments: 0

The latest Green500 list (Excel spreadsheet here) was just released at the end of June, and heterogeneous systems continue to dominate the top of the list with the new leader besting the old by nearly 30%. Two systems using Intel Xeon E5-2687W 8-Core 3.1 GHz processors coupled with NVIDIA K20’s topped the list. Eurotech’s Eurora and Aurora Tigon both broke the 3,000 MFLOPS/W barrier, record... » read more
