High Performance Computing

High performance computing (HPC) means the capacity to apply tens of thousands of processing units (PU) to a single problem. A HPC system can work on a problem in parallel and is more than a large pile of fast laptops. Without parallel processing, such simulations could take hundreds of years to perform. Typical use cases for HPC include simulations and data-analysis.

Simulations use model systems of e.g. proteins, atmosphere or galaxies and based on physics or mathematical approximations study how they behave. Accurate and realistic models can be very large and need long simulations, which require a lot of computing power.

Data-analysis typically applies different algorithms, like pattern matching or deep learning, to find correlations and understand large measurement data sets, like gene sequencing data or texts.

CSC's HPC infrastructure offers significant and versatile computing power, as well as a large selection of preinstalled software and storage. Depending on your use case, choose among our different services what suits you best. Using the HPC environments might require preliminary skills, for which we also offer training and support services.
