The LUMI pre-exascale supercomputer has a theoretical peak performance of 580+ PFlop/s and is located in Kajaani, Finland. The supercomputer was made fully operational and accepted in February 2023 and has been fully available to the Czech scientific community for one year. Czech scientists have access to Europe's most powerful supercomputer, LUMI, thanks to IT4Innovations' membership in the eponymous consortium.

Employees of Czech research organisations can apply for LUMI computing resources within IT4Innovations Open Access Grant Competitions, which are announced three times a year or via the EuroHPC JU Grant Competitions.

Within the EuroHPC JU calls, the computing resources of the LUMI supercomputer are available to users through the Benchmark Access and Development Access calls every month (continuously open calls). Applicants can request computing resources to get acquainted with LUMI, test or benchmark their software (Benchmark Access), or develop their software further (Development Access). The application deadlines for these calls, which are announced on a rolling monthly basis, are always on the first day of the month (e.g., 1 February, 1 March, etc.), and the computing resources are made available within three weeks of the application.

You can find the currently open EuroHPC JU calls here.


February LUMI course offer

We invite those interested in LUMI computing resources to take a one-day online LUMI Intro course, introducing you to the architecture and setup of the LUMI system. This one-day online course serves as a short introduction to the LUMI architecture and setup. It will include lessons about hardware architecture, compiling, using software, and running jobs efficiently. After the course, you will be able to work efficiently on both the CPU (LUMI-C) and GPU partition (LUMI-G).

The course will take place online on Thursday 8 February. →  

Users who don't have an account on LUMI yet will receive temporary access for the course purpose.


User Support - LUMI User Coffee Break

Are you a user of the LUMI supercomputer? Or are you planning to apply for access to LUMI within the IT4Innovations Open Access Grant Competition? We recommend an online meeting with the LUMI User Support Team (LUST). These meetings are called LUMI User Coffee Breaks and take place regularly on the last Wednesday of each month.

Information on the LUMI supercomputer can be found on the IT4Innovations website here.
