The Little GREEN Machine

Massive many-core supercomputer at low environmental cost

The Little Green Machine (LGM) supercomputer is a Beowulf cluster composed of off-the-shelf hardware and contains many-core Graphics Processing Units (GPUs) which offer tremendous amounts of computational power at a relative low price and energy ratio.
The machine will be built as part of the DAS4 project.

The initiators of this supercomputer are:

• Universiteit Leiden (FWN / LIACS)
• University of Antwerp (CDE)
• Utrecht University
• Royal Netherlands Meteorological Institute (KNMI)
• Delft University of Technology
• Center for Mathematics and Computer Science
