This year 2023 has been particularly difficult due to lack of public funding in the Czech Republic.
Now, the policy of the HiLASE Centre is unfortunately turning to private solutions for its IT structure, therefore our group is anticipating a fall-back to the CESNET (MetaCentrum) infrastructure to achieve small and diverse tasks.
Our large computational tasks remain attributed to IT4I, with a framework that does extraordinarily well for our needs.
The CESNET and IT4I infrastructures are free of charge for the Institute of Physics and for the Academy of Sciences, while private solution (such as Microsoft Azure, Amazon Web Services, …) must be paid instead of people using the hardly acquired funding.
These changes seemingly enforced by our hierarchy will induce a slowdown in production of scientific results for several months (notably on TDDFT and DFTB production).
EDIT of Dec 4th 2023: the political storm has now ended. We are back to normal situation.
