High-performance computing

High-Performance Computing (HPC) involves using many processing units in parallel on a supercomputer to solve complex computational problems. Supercomputers offer vast processing power and memory, making it possible to perform calculations that would be too slow or impossible on a standard computer. Today, HPC is used across almost every scientific field, from social sciences to natural sciences. CSC has a long-standing partnership with the Finnish research community – including universities, research institutes, polytechnics, and industry – providing services and support for their HPC needs.

Our HPC environments

Our HPC infrastructure offers significant and versatile computing power as well as a large selection of preinstalled software and storage. Learn about our services below and find what suits your project best.

LUMI supercomputer is one of EuroHPC’s world-class supercomputers. With LUMI, researchers are able to solve research questions requiring extremely large computing power. LUMI achieves its sustained performance of 380 petaflop/s mostly with accelerated GPU processors.
Puhti supercomputer caters to a wide range of use cases. It allows you to reserve computing and memory resources flexibly, and you can run anything from interactive single-core data processing to medium-scale simulations spanning multiple nodes.
Mahti supercomputer is in particular geared towards medium to large-scale parallel simulations requiring petaflop/s of computing power and a capable interconnect.
Allas is a general-purpose data storage service that provides an environment for storing and sharing research data. Allas can be accessed from anywhere on the internet, including all of our HPC environments.

In addition to traditional supercomputing resources, CSC also offers services for quantum computing.

Getting started with supercomputing at CSC

Using supercomputers for large calculations or datasets requires some additional knowledge, but getting started is simple, and you can build your skills over time. All of our supercomputers also have easy-to-use web interfaces that simplify access and usage for those who are more used to working with a graphical user interface.

To support new users, CSC offers extensive documentation and practical examples in our user guide Docs CSC. Additionally, introductory hands-on courses like CSC Computing Environment and Elements of Supercomputing provide materials that are suitable for self-study. For upcoming live courses, webinars and other events, please see our training calendar.

For more personalized help, CSC’s experts across various scientific fields are available to assist you in getting started and advancing your work. Do not hesitate to contact CSC Service Desk, or join one of our online support sessions!
