from Wikipedia, the free encyclopedia

LEO 3 or LEO III is a shared memory cluster supercomputer at the University of Innsbruck . LEO 3 represents the third expansion stage of this cluster and was installed in 2011. In 2015 the cluster was expanded again and is now called LEO 3E. The predecessor LEO 2 dates from 2009 and is no longer in operation.

The computer system has an energy requirement of 40 kW, an order value of € 750,000 and a total output of 18 TFLOPS.
