| 10 Dec 16:00 | Destination Earth – Vysokovýkonné počítanie pre počasie a klímu Jozef Vivoda z ECMWF – Eurpoean Centre for Medium range Weather Forecast Destination Earth (DestinE) is a flagship initiative of the European Union aimed at creating a digital model of planet Earth (Digital Twin). Due to societal and climate changes, EU countries are increasingly exposed to extreme weather impacts. Our ability to predict these changes in both the short and long term is hindered by the low regional accuracy of existing climate models. To overcome this limitation, the DestinE project is developing two distinct digital replicas of the complex Earth system. These digital twins will enable seamless integration of real-time observations with high-resolution forecasts and predictions. One of these digital twins will focus on weather-related and geophysical extremes, while the other will serve climate change adaptation purposes. | |

Is Needed to Train a Slovak Large Language Model Radovan Garabík Ľudovít Štúr Institute of Linguistics of the Slovak Academy of Sciences, v. v. i. In recent years, large language models have dramatically changed natural language processing. A breakthrough was the use of transformer architectures, which are particularly suitable for processing larger text contexts, and generative language models. What is required to create such a model that communicates in Slovak? We present the existing huge Slovak text corpora and the work that lead to the creation of the mistral-sk-7b large language model. |

Diagnostics Jaroslav Budiš z Vedeckého parku Univerzity Komenského v Bratislave Modern sequencing technologies that enable the digitization of genomic material have brought revolutionary changes in the approach to diagnosing and researching various human diseases. A key element of the process is bioinformatics tools and procedures used to analyze digitized genomic data. While these technologies have introduced new possibilities for clinical diagnostics, they also present challenges related to processing large volumes of data. | |
 | 11 Nov 18:00 | High-Performance Computing and its use in bioinformatics Michal Tamáš University of Padova, Department of Molecular Medicine High-Performance Computing (HPC) has become an indispensable tool in bioinformatics, driving advances in data analysis, modeling, and simulation. As biological data grows exponentially due to high-throughput technologies such as next-generation sequencing, proteomics, and metabolomics, traditional computing resources often need to be improved to handle the volume, variety, and velocity of the data. HPC provides the computational power and storage capacity required to process and analyze large-scale datasets efficiently. It enables the execution of complex algorithms for tasks such as genome assembly, molecular dynamics simulations, protein structure prediction, and phylogenetic analysis. |

modelling and current research topics in climate science Peter Kuma Stockholm University, Department of Meteorology (MISU) In recent decades, climate models have become an integral part of climate science. They allow us to not only predict the Earth's future climate but also to reconstruct the past and better understand the present climate. In this talk, you will learn how they work, what supercomputers they run on, and the broader context of climate change and human impact on the climate. | |
| < | 22 Okt 16:00 | Unraveling the Mysteries of DNA Using High-Performance Computing DUŠAN RAČKO Ústav polymérov SAV, v. v. i. The DNA molecule that carries the instructions for life is like a super-twisted rope or spiral ladder forming a shape known as a double helix. It's not just an ordinary molecule - it's a polymer. That is, it forms long chains of repeating building blocks. Thanks to its unique shape, DNA can twist, bend and form complex structures, including knots and chains, which are special kinds of topologies about which scientists are still learning a lot. |
 | 14 Maj 16:00 | Úvahy o úlohe vysoko výkonných počítačov (HPC) a grafických procesorov v genómovej analýze DNA MILOSLAV KARHÁNEK Biomedicínske centrum SAV, v. v. i. Využitie „open source“ bioinformatických nástrojov pre genómovú analýzu na HPC môže byť problematické z hľadiska ich slabej paralelizácie na úrovni jednej analyzovanej DNA vzorky. Paralelizácia týchto nástrojov na HPC je možná tak, že sa analýzy spustia na viacerých vzorkách. Využívaniu HPC dnes konkurujú grafické procesory a karty, na ktorých je možná paralelizácia už na úrovni jednej vzorky. Dobrým riešením by preto mohlo byť umožnenie kombinovaného využitia HPC a grafických kariet a veľkokapacitného úložiska. |

konformačných preferencií prirodzene neusporiadaného proteínu
tau ONDREJ CEHLÁR Neuroimunologický ústav SAV, v. v. i. Prirodzene neusporiadaný proteín tau, ktorý zohráva úlohu v patogenéze Alzheimerovej choroby, nenadobúda za fyziologických podmienok stabilnú 3D štruktúru, na rozdiel od globulárnych proteínov, ale fluktuuje medzi rôznymi konformáciami. Jeho štruktúru je možné opísať ako súbor prechodných konformácií, ktoré sú rôznou mierou zastúpené – tzv. konformačný ensemble. Na jeho popis je možné využiť rôzne experimentálne metódy, ako napríklad NMR spolu s výpočtovými metódami simulácie molekulovej dynamiky (MD), na ktorú využívame HPC prostriedky. Jedným príkladom využitia je popis konformačného správania krátkeho peptidu z prolínovej oblasti tau proteínu vo voľnom stave pomocou MD simulácie, ktorý je možné porovnať s konformáciou získanou pomocou Röntgenovej kryštalografie z komplexu tau peptidu so špecifickou protilátkou. | |
| 9 Apr 17:00 | Zvedavá umelá inteligencia MATEJ PECHÁČ Faculty of mathematics, physics and informatics, Comenius University Zvedavosť, ako druh motivácie, je jedným zo základných fenoménov vyskytujúcich sa u živočíchov s vyššou kogníciou. Poháňa a riadi ich správanie tak, aby boli naplnené ich potreby na rôznej úrovni. Je základnou vlastnosťou, ktorá zabezpečuje neustály vývoj jedinca a vedie k jeho zdokonaľovaniu. Na tejto prednáške si ukážeme, ako formalizovať zvedavosť / motiváciu a ako ju pridať k AI agentom. Zároveň na jednej z veľmi ťažkých úloh v oblasti rozhodovania dokážeme, že pridanie zvedavosti výrazne pomôže s jej riešením. | |

| 7 Dec 17:00 | Federated distributed computing Ladislav Hluchý Institute of Informatics SAS Thanks to powerful servers and large data storages, a significant progress can be seen in distributed computing, where the performance achieved is very high (dozens of PFLOPS). In a not-too-distant past we saw the computing clusters being built from personal computers, progressing to powerful servers and data storage units later on. Since 2000 there was a boom of building grid-based distributed infrastructures with distributed operation systems. With the birth of cloud technologies, distributed computing has taken on a new dimension. IT companies such as Google, Amazon, Microsoft, IBM, ATOS brought their technologies to market. The federated cloud infrastructures were introduced, with the support of the European Commission, to avoid the so-called vendor lock-in situation. The individual national cloud infrastructures can join the federation, allowing researchers to run their calculations on an infrastructure that does not impose technological constraints. | |
