The EuroHPC LUMI supercomputer currently being implemented in Kajaani, Finland will be one of the world's fastest computer systems with over 550 PFlop/s of performance. The LUMI supercomputer is procured jointly by the EuroHPC Joint Undertaking and the LUMI consortium.

LUMI Call for pilot projects from Czech Republic

The aim of this call is to generate stress-testing load on the newly installed CPU partition of the LUMI supercomputer while satisfying real-world needs and in particular to stress test the storage systems for the purpose of stability testing. Further, we aim to provide early access to the LUMI supercomputer to obtain feedback before the launch of regular operation. The availability and technical readiness of the system (e.g. installed software) is not guaranteed and unexpected maintenance breaks may occur during this pilot phase.

Two projects will be selected for each country participating in the LUMI consortium. Therefore, only two projects will be selected from the Czech Republic!

The general principle in the selection for this call is to favor cutting-edge research. The selected users/user groups are also expected to have the sufficient technical capability to be able to prepare for the pilot use (with support from CSC if needed) and execute their pilot code right from the start of the pilot code execution phase. The pilot users are expected to report findings and feedback about the system performance, performance variations, computing environment etc.

Computational resources to be distributed:
There is no accounting of the consumed resources in this call, awarded projects are welcomed to burn as much computer time as possible within the time period. However, there is also no guarantee how much computer time will be actually available.

Technical parameters of the LUMI-C partition:
x86_64 architecture. Over 200 000 AMD EPYC CPU Cores.

Application submission deadline:
March 17, 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 financed from the Czech Republic’s public resources. Citizenship does not affect applicants’ eligibility.
