The updated list of the world’s top 500 supercomputers  was released yesterday, and includes energy efficiency data about these powerful systems, as noted by ComputerWorld  (link via Dave Ohara ). Jack Dongarra, a professor at the University of Tennessee and co-creator of the Top 500 list, said that the supercomputers of the future may require as much as 100 megawatts of power. Systems under development at Oak Ridge National Lab will have annual power bills of more than $30 million when they debut in 2012. An excerpt:
“Power consumption is becoming one of the most important aspects of computing,” said Dongarra. “It will be the most important driving force for supercomputing in the future. Without focusing on that, building bigger machines will be prohibitive. We’re trying to understand which machines are more efficient, why they’re more efficient, and understand the trends in high-performance computing.”
The good news: the most powerful systems are also the most energy efficient, reflecting the benefits of the latest technology.
That trend was on display in an analysis of the power efficiency of the top 500 . The key findings:
The most energy efficient supercomputers are based on IBM’s QS22 Cell processor blades (up to 488 Mflops/Watt), followed by IBM BlueGene/P systems at up to 371 Mflops/Watt.
