Sydney Uni seeks HPC energy cost reduction with new algorithms

Newly developed algorithms may be the solution to reducing the increasing energy consumption and cost of high performance computing (HPC) networks, according to University of Sydney director of HPC, Professor Albert Zomaya.
Speaking to CIO Australia, he said that in the last few years the University has patented a “very sophisticated” algorithm which performs energy reduction.
"That algorithm deals with energy consumption by manipulating voltages at a processor level,” Zomaya said.
“We know that modern processors can operate at different voltage levels and by manipulating these voltages we are able to run a workload without compromising the execution time or the quality of service while at the same time reducing the energy consumption of the platform."
According to the professor, this platform could be a small or medium sized data centre which has hundreds of processors.
Some HPC systems use megawatts of electricity for operation and cooling, Zomaya said.
“On average, power bills for such systems can run in the millions per year.
“From the results we obtained from our extensive algorithm simulations we can see that, depending on the nature of the [HPC] application, the savings can run from five per cent to 35 per cent.”
On average, HPC network operators could save at least 15 to 20 per cent in energy bills if they used the algorithm.
While the algorithm has not been released for commercial use yet, the University of Sydney has implemented an extended version of the algorithm on a prototype data centre at its HPC division.
“We currently have two prototype data centres in the HPC centre as we’re running different hardware, metering and tools,” he said.
This is so university staff can gauge the exact energy consumption levels and experiment with different workloads to get a more complete picture of energy consumption profiles.
“The hope is that within the next six months we should be able to have some of these solutions implemented in the hardware and properly tuned to deal with different case studies,” Zomaya said. “After we do the prototyping here it will be nice to run this [algorithm] in a production environment to see how it is going to perform over a long period of time.”

Leading Through Connections – Insights from the Global Chief Executive Officer Study
IBM’s 2012 Global CEO study follows face-to-face discussions with more than 1,700 CEOs and senior public sector leaders from around the globe. The findings examine how CEOs are responding to the complexity of increasingly interconnected organisations, markets, societies and governments. For example, almost one-quarter of CEOs say their organisations operate below par in terms of driving value from data. CEOs have expressed frustration about their inability to capitalise on available information. This is because: “The time available to capture, interpret and act on information is getting shorter and shorter.” CEO, Chemicals and Petroleum, United States Given the need for deeper business insight, the best performing organisations are more adept at converting complex data into insights, and insights into action.

The Power of Cloud
Although cloud is widely recognized as a technology game changer, its potential for driving business innovation remains virtually untapped. To take advantage of cloud’s potential to transform internal operations, customer relationships and industry value chains, organisations need to determine how best to employ cloud-enabled business models that promote sustainable competitive advantage.

Implementing A Security Analytics Architecture
According to the 2012 Verizon Data Breach Investigations report, 99% of breaches led to data compromise within “days” or less, whereas 85% of breaches took “weeks” or more to discover. This presents a significant challenge to security teams as it grants attackers extended periods of time within a victim’s environment. More “free time” leads to more stolen data and more digital damage. Principally, this is because today’s security measures aren’t designed to counter today’s more advanced threats. Read on.
