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

38th OPEN ACCESS GRANT COMPETITION OF IT4INNOVATIONS

This round of the Open Access Grant Competition is open until 27 July 2026. You can apply for computational resources on the Barbora NG, Karolina and LUMI supercomputers, as well as the VLQ quantum computer.

Please note the new Computing Time Allocation Rules.

Computational resources to be distributed (up to 10% of the resource offered per request):

  1. Barbora NG: 160 000 node hours (max. per request: 16 000 node hours)
  2. Karolina CPU: 1 156 000 node hours (max. per request: 115 600 node hours)
  3. Karolina GPU: 111 000 node hours (max. per request: 11 100 node hours)
  4. Karolina FAT: 1 400 node hours (max. per request: 140 node hours)
  5. LUMI-C: 111 000 node hours (max. per request: 11 100 node hours)
  6. LUMI-G: 155 000 node hours (max. per request: 15 500 node hours)
  7. VLQ: 2 177 000 QPU seconds (max. per request: 217 700 node hours)

Technical parameters of the Barbora NG supercomputer: 
144 non-accelerated compute nodes, each node is a powerful x86-64 computer equipped with 192 cores (2x Intel Xeon 6952P with 96 CPU cores) and 768 GB RAM.

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 LUMI supercomputer:
LUMI-G consist of 2560 nodes, each node with one 64 core AMD Trento CPU and four AMD MI250X GPUs.
LUMI-C is using CPU only nodes, featuring 64-core 3rd-generation AMD EPYC™ CPUs, and between 256 GB and 1024 GB of memory.

Application deadline:
2 June – 27 July 2026

Eligible applicant: Employee of a Czech research organisation 
* New applicants (without previous experience with IT4Innovations computing systems) must have at least one successfully completed project under Fast Track Access (FTA).

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: 28 September 2026

The period to use computational resources obtained:
The drawdown will be granted for a period of 12 months from the start of the drawdown, which is expected to start on 30 September 2026.
For multi-year projects, depending on the chosen project duration, the drawdown will be granted for 24 or 36 months from the start of the drawdown.

Call type: Open

Mandatory acknowledgement of the achieved R & D results:
This work was supported by the Ministry of Education, Youth and Sports of the Czech Republic through the e-INFRA CZ (ID:90254).

For the correct assignment of e-INFRA CZ to the R&D results when exporting them to RIV, see USER'S DUTIES. 

Date of announcement of the next open access competition: October 2026

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 24 or 36 months. The purpose is to support long-term scientific grants.
