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.

24TH Open Access Grant Competition of IT4Innovations


Due to problems with the electricity supplier we are forced to limit the operation of our supercomputers. This restriction is likely to last until the end of January.

The selection of a new energy supplier is ongoing and until a selection decision is made, no decision can be made on the actual available capacity and therefore allocations.

We will keep you informed of further development asap.

DON`T MISS: This call also includes a special GPU Testing and Benchmarking call, which aims to allow as many researchers from the Czech Republic as possible to test and gain experience with the GPU-accelerated part of the Karolina supercomputer.

Computational resources to be distributed in NODE HOURS:

  1. Barbora CPU: 430 000 node hours (15 480 000 CPU core hours)
  2. Barbora GPU: 18 000 node hours (72 000 GPU hours)
  3. Barbora FAT: 2 200 node hours (105 600 CPU core hours)
  4. DGX-2: 2 200 node hours (35 200 GPU hours)
  5. Karolina CPU: 1 100 000 node hours (140 800 000 CPU core hours)
  6. Karolina GPU: 100 000 node hours (800 000 GPU hours)
  7. Karolina FAT: 1 500 node hours (1 152 000 CPU core hours)

Technical parameters of the Barbora supercomputer:
192 compute nodes without accelerators, 8 compute nodes with 4x NVIDIA Tesla V100-SXM2 GPU accelerators, 1 FAT node for large-scale data analysis equipped with 6 TB of shared memory, 2 visualization nodes.

Technical parameters of the Karolina supercomputer:
720 compute nodes without accelerators, 72 compute nodes with 8x NVIDIA A100 GPU accelerators (40 GB HBM2), 1 FAT node for big data analytics with up to 24 TB shared memory, 2 visualization nodes, 36 nodes for cloud services.

Technical parameters of the NVIDIA DGX-2 supercomputer:
1 compute node with 2x Intel Xeon Platinum processors and 16x NVIDIA Tesla V100 GPU accelerators (32 GB HBM2).

Application deadline:
October 7, 2021 – December 2, 2021

Eligible applicants:
Employees of academic and research institutions who have their registered offices or a branch in the Czech Republic. Furthermore, persons and entities that have acquired and/or participate in implementing a research grant from the Czech Republic’s public resources. Citizenship does not affect applicants’ eligibility.

How to submit an application:
Applications will only be accepted in English.

The application form:

Please submit the form via the web portal.

Date of announcement of results:
January 20, 2022

The period to use computational resources obtained:
Estimated start on January 27, 2022. Estimated end for standard projects is on October 24, 2022. For multi-year projects, drawdown will be granted for 18, 27 or 36 months from the start of drawdown, depending on the chosen project length.

Call type: Open

Evaluation of applications:
Three areas will be evaluated: The Scientific excelence, Computational readiness and Socioeconomic impact. The evaluation and scoring will be carried out by external reviewers, following the Open Access evaluation guidelines. Scientific excellence, Computational readiness and Socioeconomic impacts of the application will be evaluated. The allocation committee will take into account connection of the project to other projects or grants: international (H2020, EuroHPC, ERC, …), national (GAČR, TAČR, …) or local (Student grant competition, …), to the extent and detail of requested resource estimation and to the expected applied outputs such as patents or contracts.
The weight of 50% will be assigned to the publications achieved as a result of previous projects at IT4I, registered at On average 1 publication per project is expected. The latter will be only applied to projects older than 15 months. Applicants will be notified of the competition results within 35 working days of the conclusion of the competition. Notifications will be sent in electronic format to the e-mail address specified in the application.

Mandatory acknowledgement at the achieved results:
This work was supported by the Ministry of Education, Youth and Sports of the Czech Republic through the e-INFRA CZ (ID:90140).

Date of announcement of the next open access competition:
February 4, 2022

multi-year approach

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.
