World’s smallest super computer

18 May 2017 by web editor

The Little Green Machine (LGMII) was built under the direction of Simon Portegies Zwart (Leiden University) in collaboration with DCSE with funding of NWO. The LGMII is a super computer with a power that strives beyond 10.000

regular computers.

There are specific applications for which DCSE researchers will use the machine in the TU Delft. For example, “we will be modelling climate changes and water flow using the LGMII”, Kees Vuik states. And all of that is possible with such a small and cheap object.

Power

The successor of the Little Green Machine I has the extreme power of almost 0.5 Petaflops that can result in 500.000.000.000.000 calculations a second. The machine can be used in many other domains as well, like

oceanography, informatics, artificial intelligence, algorhytmics, financial modelling and astronomy.

 

Colliding stars

We, researchers of DCSE, made our supercomputer in collaboration with our partners by combining four

graphical cards in a super-fast network. We simulated the collision between the Milky Way and the Andromeda

Galaxy that will occur in about four billion years from now. Just a few years ago, researchers performed the same simulation at the huge Titan Computer (17.6 petaflops) at Oak Ridge National Laboratory (USA). Now we can

calculate such a simulation much faster and more accurate.

The simulation of the collision of the clash in our galaxy in addition explains the name of this super computer. The catchy name comes from the first pulsar ever discovered by Jocelyn Bell-Burnell in 1967: the Little Green Men.

 

It is evident that this computer has many more difficult calculations and models to work with in the future that it can execute accurate and super-fast.
