Computing Resources and Services

Links to our state-of-the art computing environments and cloud services, and to international computing resources.

Supercomputer Puhti

The air-cooled supercomputer Puhti allows users to run serial and small parallel jobs through a batch queueing system. Puhti includes CPU based nodes with a range of memory, and nodes with Nvidia VoltaGPUs (Puhti-AI) for HPC and AI workloads.

HPC-Europa 3

HPC-Europa is an EC programme which funds researchers to carry out short "transnational access" visits to other countries to collaborate with another research group and provides access to supercomputers at the host country.

Grid computing

Grid computing enables applying the resources of many computers or computing clusters in a network to a single problem at the same time. The grid combines various computing resources, data banks, and measuring devices that comprise a pool of resources for coordinated, integrated and flexible shared use.

High performance computing

High performance computing (HPC) means the capacity to apply tens of thousands of processing units 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.

CSC currently hosts two supercomputers: Puhti and Mahti. Puhti's use cases vary from interactive single core data processing to medium scale simulations, while Mahti is geared towards medium to large scale simulations.

One of the EuroHPC world-class supercomputers, LUMI, will be taken into use early 2021. It will be one of the most competitive supercomputers in the world for research purposes.

Cloud Computing

CSC offers a variety of cloud computing services: the Pouta IaaS services and the Rahti container cloud service.

With the Pouta services, you can can take the control of your IT infrastructure, manage it in flexible fashion, and automate it as you require. You can launch and manage virtual machines, deploy storage, and create networks for your needs. This infrastructure can be used for anything you need, or can imagine.

Rahti makes the deployment of applications a breeze. This is a higher level service than the Pouta services, and Rahti automatically takes care of a lot of the lower level management - so that you don't have to. Rahti is based on Red Hat's OKD, which is a distribution of Kubernetes and uses Docker containers to run applications.

Our services are hosted in Finland, assuring that your data is safe in our data centers. The systems are connected to the high performance Funet network. Both platforms are available as a commercial service as well.

The cPouta and Rahti services are available to any user with access to the computing services at CSC, while the ePouta service is primarily targeted to IT administrators of organizations.

Special Resources and Projects

If the computing or storage resources offered by CSC through the normal allocation process are not sufficient or adequate for your needs, there are a number of options to turn to:

  • Normal CSC resource allocation process
  • The Finnish Grid and Cloud Infrastructure (FGCI)
  • CSC Grand Challenge project calls
  • Partnership for Advance Computing in Europe (PRACE)
