Scientists from Frankfurt´s Goethe University and the Karlsruhe Institute of Technology (KIT) developed a system that substantially reduces the energy consumption for processing huge amounts of data. They improved over the power efficiency of the former record holders from Stanford University by a factor of three to four.
The record is listed in the "sort benchmark," which is published by companies like Hewlett-Packard and Microsoft.
The team around Prof. Ulrich Meyer from Goethe University and Prof. Peter Sanders from KIT enabled the record by using seemingly unconventional hardware: instead of server processors with high power requirements, the computer scientists took processors of type Intel Atom. These are microprocessors originally developed for netbooks.
