Dossiers
On this part of the website, you will find more information about certain aspects of our work. This is intended to offer our customers some background about particular techniques. But this section is certainly also meant for other visitors of the website that share our professional interests. You are invited to give us suggestions for additional information to be placed in the dossiers.
Dossier High Performance Computing
High Performance Computing (HPC) is all about doing extremely large computations in the shortest possible time. The ultimate goal of HPC is to compute things that today take too much computing time or require too much memory. But the same methods and techniques are used to make more conventional computations faster. Or to do much more accurate computations in the same amount of time.. Read more>>
Dossier data assimilation
Data assimilation is the use of observations in computer models in order to improve the reliability of the outcome of the models. An important application is found in meteorology. There, a prediction model starts by simulating the past few days and during that period, it is constantly adjusted to stay close to the available observations. When the model then goes on to simulate the next few days, the initial situation of the model will closely match the current reality and the predictions are bound to be more reliable than without data-assimilation. But there are also other ways to meaningfully combine observations and models: for calibration, for interpolating or extrapolating observations or to compute back from an observation to the likely cause of that observation.
