Demonstration of the Netherlands' smallest supercomputer at TU Delft Institute for Computational Science and Engineering kick-off event

News - 17 May 2017

The Little Green Machine II is a supercomputer with the computing power of 10,000 PCs, the size of four pizza boxes and electricity consumption just 1% of that of a comparable large supercomputer. At the kick-off event for the TU Delft Institute for Computational Science and Engineering (DCSE) on Tuesday 23 May, project manager Simon Portegies Zwart (Leiden University) will give a demonstration of this small-scale computing miracle.


Computational Science & Engineering is a rapidly growing field in which applied mathematics, engineering and sciences, including social sciences, converge. The TU Delft Institute for Computational Science and Engineering brings together the expertise of six TU Delft faculties: more than 40 research groups, over 200 scientists and more than 100 PhD candidates. DSCE is all about linking up engineering, mathematical modelling and computer science. Scientists at the DCSE incorporate scientific techniques and simulations in models that can be directly used in industry.

Little Green Machine II

The compact supercomputer that will be showcased at the kick-off event on 23 May was made by a team of Dutch researchers (some from TU Delft) by connecting together four PCs each with four special graphic cards via a superfast network. The computer will be used by researchers in such varying fields as oceanography, computer science, artificial intelligence, algorithmics, financial modelling and astronomy. The computer was developed with the help of IBM hardware. More information about this supercomputer:

Combining computational power with modelling

‘As far as speed is concerned, standard hardware has more or less reached its peak. This is why we urgently need an alternative strategy, such as parallel computing and graphics cards – Little Green Machine II does that too’, says Prof. Kees Vuik, director of the DCSE.
‘Traditional measuring and testing methods are no longer sufficient for modelling complex systems such as the climate or the human immune system. Computer simulations can provide a solution in this. This is why, alongside theory and experimentation, Computational Science and Engineering is also referred to as 'the third mode of discovery'. The enormous power of computers today and the advanced numerical models and mathematical algorithmics makes Computational Science and Engineering essential for industry and science.’
