Now, an energy-efficient computer system!
London: In what could be called a major
step towards green computing, scientists in Germany claim to
have developed a system that substantially reduces the energy
consumption for processing huge amounts of data.
A team from Goethe University and Karlsruhe Institute
of Technology in Frankfurt has used seemingly unconventional
hardware and instead of server processors with high power, the
scientists took processors of type Intel Atom, microprocessors
originally developed for netbooks.
Their lower processing power compared to server
systems was compensated by the usage of highly efficient
algorithms. Instead of hard drives, which consume a lot of
power for the mechanics, the team employed so-called Solid
State Disks (SSD), which are clearly faster and, at the same
time, more power-economical.
And, thus the German team improved over the power
efficiency of the former record holders from Stanford
University by a factor of three to four.
The record pops the question if the increasing
hunger for energy in information technology could be strongly
reduced. "In the long run, many small, power-efficient and
cooperating systems are going to replace the so far used,
heavy weighted ones," said lead scientist Peter Sanders.
