Computational resources of the centre are dedicated for solving problems from research and development done by academic and research institutions. Part of the capacity is dedicated for development of collaboration between academia and industry, or for industry itself.

Open Access Competition

Institutions can apply for computational resources within Open Access Grant Competitions. The grant competition is announced 3 times a year (February, June, October) for employees of research, scientific and educational organizations.

recent open call


You can also apply for projects in the form of "multi-year" open access, in which computing resources are provided for a period of 18, 27, or 36 months. The purpose is to support long-term scientific grants.

More about the multi-year approach 

LUMI Supercomputer computational resources 

The EuroHPC LUMI supercomputer, currently being implemented in Kajaani, Finland, will be one of the world’s fastest computing systems with performance over 550 PFlop/s. The LUMI supercomputer is procured jointly by the EuroHPC Joint Undertaking and the LUMI consortium. IT4Innovations is one of the LUMI consortium members. LUMI will be one of the world’s best known scientific instruments for the lifespan of 2021–2026.

LUMI-G Call for pilot projects from the Czech Republic

The aim of this call is to provide pilot access to the newly installed GPU part (LUMI-G) of the LUMI supercomputer in order to obtain feedback before the launch of regular operation.

More about the lumi-G open call

In the spring of 2021, two pilot projects for the LUMI supercomputer CPU part from the Czech Republic were choosen. Meet the winning projects.

EuroHPC JU grant competitions  

European High Performance Computing Joint Undertaking (EuroHPC JU) is a joint initiative between the EU, European countries and private partners to develop a world-class supercomputer ecosystem in Europe. 
Within the EuroHPC, seven supercomputers are being set up across Europe: LUMI in Finland, Leonardo in Italy, MeluXina in Luxembourg, Vega in Slovenia, Karolina in the Czech Republic, Discoverer in Bulgaria and Deucalion in Portugal. 
The Czech Republic is participating in this initiative. All EuroHPC supercomputers are available for users from the Czech Republic.

EuroHPC Benchmark and Development Acccess 

The Call for Proposals for EuroHPC JU Benchmark and Development Access Modes are continuously open calls. The evaluation of submitted projects is performed once a month for all projects submitted by the cut-off date, which is on the 1st of the given month. Access to resources can be obtained within two weeks from the cut-off date. 

Detailed information can be found on the EuroHPC Access website.

Directors` Discretion

Furthermore, 5 % of the IT4Innovations computational resources can also be granted to projects upon request within the Directors’ Discretion scheme. An application can be submitted at any time. The computational resources are allocated irregularly based on evaluation by the IT4Innovations management. Representatives from both commercial and non-commercial sectors can apply in case Open Access Grant Competitions cannot be used.

The application form is available after registration here: DOCX or ODT. Applications will only be accepted in English, in case of the commercial entities, Czech language is accepted. Please submit the form via the web portal.

This is a 182-day period, upon individual agreement in case of cooperation with commercial entity.

Applications may be reviewed by external reviewers. Applicants will be notified of the competition results within 20 working days of the submission of the application. Notifications will be sent in electronic format to the e-mail address specified in the application.

rental of computational resources

IT4Innovations offers commercial companies the opportunity to rent the computational resources of the operated supercomputers. Companies interested in using this service may choose based on their preferences from the following modes:

Standard allocation arranged for a specific period with a pre-agreed quota

This is essentially a rental mode based on shared access to computational resources with other active users, with a total number of core hours negotiated in advance, and includes the provision of standard user support.

Customized allocation

A rental mode offering the opportunity, for example, to use a pre-agreed number of compute nodes arranged for a certain period allowing instant access to computational resources as compared to the standard allocation.

If you decide to use our services and would like to rent the computing time, use our form to do this. If you wish to modify an existing contract for renting the computing time, use this form. Finally/Subsequently, submit these forms through our web portal.

The rental of computational resources is governed by the general terms and conditions. We perform billing in normalized core hours.

other options for obtaining computational resources

The IT4Innovations National Supercomputing Center also helps interested Czech entities in obtaining computing time in European supercomputing centres associated in the PRACE RI initiative.

PRACE Preparatory Access

Grant competition announced regularly 4 times a year subject only to a technical assessment; its aim is to prepare projects for participation in PRACE Regular Access.

PRACE Regular Access

Grant competition announced regularly twice a year subject to a scientific assessment; computing time is assigned in Tier-0 systems.

DECI Calls

Grant competition announced regularly twice a year, suitable for smaller projects; computing time is assigned in Tier-1 systems.
