High Performance Computing

Typical use cases for high performance computing (HPC) include simulations and data analysis.


Simulations commonly use the model systems of very small or very large scale phenomena, such as proteins, atmosphere, or galaxies. Simulations help you study how they behave based on physics or mathematical approximations. Accurate and realistic models can be very large and need long simulations, which requires a lot of computing power.

Data analysis

For data analysis, HPC is useful in finding correlations and understanding large measurement data sets. Different algorithms can be used for these purposes, for example, pattern matching or deep-learning algorithms. HPC can therefore be applied in such tasks as analyzing gene sequencing data or texts.
