CSIRO in world's top 11
Press Release (20/11/2010)

CSIRO's graphics processing unit (GPU) cluster is now Australia's 'greenest' supercomputer ranking 11th on an internationally recognised list of the world's 500 fastest and most energy efficient supercomputers - the Green500 List.
Announced today at the international SC10 supercomputing conference in New Orleans, the Green500 List is a ranking of the TOP500 supercomputers by energy efficiency (performance speed per Watt of energy consumed).
It highlights the growing power consumption of the world's fastest computers and encourages owners to reduce their carbon footprint by using technology that improves energy efficiency.
″We were able to build a faster, greener supercomputer at a fraction of the cost using GPUs″ Dr John Taylor CSIRO's GPU cluster ranked number 145 on the Top500 list earlier this week, performing the Linpack benchmark at 52.55 Teraflops in double precision, with an energy efficiency of 555.5 MegaFlops/Watt.
″We knew we had a fantastic computational facility in our GPU cluster, but we are particularly delighted to near the top of the Green500 List,″ said Group Executive Information Sciences CSIRO, Dr Alex Zelinsky.
″GPU computing really fits well with our e-Research strategy and has proven to be a great success for CSIRO over the past year.
This new high performance computing technology has accelerated our scientific research and put us on the world stage alongside China, Europe and the United States.″ CSIRO's GPU cluster, recently upgraded by Xenon Systems, combines Intel Central Processing Units (CPUs) with 64 NVIDIA Tesla S2050 graphics processing units (GPUs) - an industrial version of the graphics cards found in game consoles and computers.
GPU-based supercomputers are twice as energy efficient as regular CPU supercomputers, completing calculations around 10-100X faster than CPUs.
GPUs are also much cheaper to purchase and occupy half the rack space which reduces cooling and data centre costs.
CSIRO's Computational and Simulation Science leader, Dr John Taylor, said energy efficiency and value for money were big draw cards for CSIRO.
″We were able to build a faster, greener supercomputer at a fraction of the cost using GPUs.
″We're solving big national research problems at CSIRO, particularly in climate and environmental science, so it's important that we walk the talk when it comes to sustainability,″ Dr Taylor said CSIRO scientists using the GPU cluster have already seen dramatic performance speed-ups on a range of research projects from 3D image reconstruction, analysing genetic data from wheat breeding experiments and modelling interactions between nutrients and plankton in the oceans.
″Making the Green500 List and seeing the speed ups scientists are achieving has certainly validated our decision to explore this technology and, one year on, it's really paying off for CSIRO,″ Dr Taylor said.
CSIRO is also a joint partner in other high performance supercomputers featured on the TOP500 list including: the National Computational Infrastructure (NCI) facility #51, iVEC system in Western Australia #87 and the Bureau of Meteorology/CSIRO Sun Blade System #161.

M+H Power and Advanced Power have rebadged into MPower in a move that consolidates its UPS and green solutions into the one company. Headed up by Paul Sharp as managing director, the new company is as much a public information exercise as it is a rebadging. Operating under Advanced Power, M+H Power, Leda, Ultimate, Powerblock, Bardic, Westpower, Nikko, Hushmate, Workmate and PowerHouse; the old entities that came from past takeovers and mergers and were often regarded singularly. The merging into the one identity has already worked sparking interest from companies unaware the scope and breadth of the old company. “We have since picked up jobs in the renewable energy areas when they became aware of our product range and experience,” Paul Sharp said. “Now our offerings of stored, emergency, generated and green power solutions are represented by a single identifiable brand.”

IntelliPower Inc has a field proven fully isolated 1U rugged model includes autoselect for inputs of 115 or 230Vac, 50/60Hz, with power factor correction with an output provides an output of 115Vac or 120Vac. Output frequency can be 50/60Hz as a frequency follower or fixed at 60Hz. The output inverter can handle high surge loads of 40A plus without needing to use bypass and it is rated for -10C to +50C. This model includes batteries to support a 500W load for 14 minutes and communications capabilities include SNMP or RS232. It has been tested to meet MIL STD 461E CE101, RS103, FCC class A as well as MIL STD 810F for shock and vibration mounted in a tactical transit case.

The Powerstar inc Smart-UPS Shipboard series includes a double-pole circuit breaker that will protect lines from overload and a double-pole power switch to insure the attached load is completely removed from the input power lines. These are necessary because a ship generates Delta power causing both power lines to be "hot".
