Computer scientists from Frankfurt's Goethe University and the Karlsruhe Institute of Technology (KIT) have set a new world record in energy-efficient data processing. The new system improved on the work of a Stanford University team by a factor of three to four.

Ph.D. candidates Johannes Singler and Andreas Beckmann used Intel Atom processors for the data processing system rather than server processors that use more power. Their lower processing power compared to server systems was compensated by the usage of highly efficient algorithms. Moreover, the team used solid state disks, which are faster and use less power, rather than hard drives.

The data processing system sorted data amounts of 10 Gbyte, 100 Gbyte and 1 Tbyte, respectively, consisting of datasets with 100 bytes each. When sorting 1 Tbyte of data, the system only spent 0.2 kWh.

"In the long run, many small, power-efficient and cooperating systems are going to replace the so far used, heavy weighted ones," says professor Peter Sanders from KIT, a supervisor of Singler and Beckmann.
