Účastníci získali prehľad o základných pojmoch a definíciách, ako operačný systém umožňuje a zabezpečuje prístup aplikácií a procesov k prostriedkom a ako tieto prostriedky spravuje. Dozvedeli sme sa viac o stavoch a zmenách stavu jednotlivých procesov. Zaujímavé boli aj informácie o tom, ako vyzerá politika a réžia plánovača (scheduler), ktorý prístup na CPU procesom prideľuje.

Z hľadiska vysokovýkonných výpočtových prostriedkov nás zaujíma, ako funguje OS v prostredí s mnohými procesormi. Zvyšovanie počtu procesorov je prirodzenou odpoveďou na rýchly nárast požiadaviek aplikácií a súčasne limitov zvyšovania výkonu jediného CPU. Operačný systém teda môže úlohy rozdeľovať medzi viaceré fyzické procesory (alebo jadrá), pričom tieto procesy sú nezávislé a môžu bežať súbežne. Programátori môžu využiť výhody viacerých procesorov a svoje úlohy rozdeliť na viacero súbežných podúloh. Tieto už ale nie sú nezávislé a väčšinou je potrebné, aby medzi sebou navzájom komunikovali. Jedna úloha – proces môže mať teda viacero samostatných tokov riadenia, ktoré nazývame vlákna (threads) a ktoré zdieľajú väčšinu prostriedkov tohto procesu, vrátane pamäte. Z pohľadu architektúry to môže vyzerať ako na obrázku ilustrujúcom schému symetrického multiprocesorového systému (Obr. 2), kde je jedna pamäť zdieľaná viacerými rovnocennými procesormi (architektúra UMA – Uniform Memory Access). Tu je potrebné ošetriť synchronizáciu prístupu k tejto spoločnej pamäti, čo je možné urobiť viacerými spôsobmi. Prístup SMP – symetrického multiprocesingu má však nevýhody ako zlá škálovateľnosť, čakanie pri synchronizácii, tzv. cache trashing.

Ak fyzickú pamäť rozdelíme na viaceré moduly, dosiahneme menšie zaťaženie zbernice, pretože procesory budú najviac využívať vlastnú lokálnu pamäť. Tento prístup poznáme ako NUMA – Non-Uniform Memory Access. Tu je najvýhodnejšie, ak OS alokuje úlohe pamäť pre dáta čo najbližšie k procesoru, na ktorom úloha beží. Na obrázku vidíme príklad prepojenia 4 procesorov:

Prednáška pokryla aj tému správy pamäte, virtuálnu pamäť a jej alokáciu – vrátane konceptu overcommit a tému súborového systému a jeho hierarchie.

Operačné systémy a ich fungovanie v HPC prostredí by si určite zaslúžili aj viac priestoru, ako náš formát môže poskytnúť. Ak vás téma zaujala, na Fakulte matematiky, fyziky a informatiky UK na túto tému prednáša práve Dr. Dušan Bernát – a ak ste našu prednášku nestihli, môžete si ju pozrieť na Facebook or YouTube.

The following panel discussion, organized with the support of the NCC, highlighted the situation in HPC in Slovakia. Lukáš Demovič, who is the director of the Centre of Operations,  Slovak Academy of Sciences - an institution operating the only publicly available HPC infrastructure – spoke about the current possibilities, ongoing projects and ambitious plans for significant expansion of computational capacities in Slovakia. The importance of investments and support of this field was stressed also by other speakers. Prof. Ivan Štich, who is active within the TREX CoEshowed use cases of 2D materials modelling using the QMC method,, which is, thanks to it’s robustness and scalability, especially suited for utilizing the coming exascale systems. Prof. Mária Bieliková from the Kempelen institute of intelligent technologies introduced a newly developed large neural language model for Slovak. She also mentioned the aspect of large energy consumption that comes with many AI applications and models together with the strategies scientists employ to mitigate this problem. Jozef Vivoda described models for numerical weather forecasting, employed and (co)developed at the Slovak hydrometeorological institutetheir level of precision as well as computational demands. Robert Cisár from the Tachyum company and Luboš Kolář from HPE took part in the discussion as representatives from the private sector.

All speakers agreed on the necessity of investing into HPC technologies at the national level and the importance of supporting the whole ecosystem at the same time. The lack of concept on the state level and the lengthy and disproportionately complicated process of public procurement were identified as main problems when planning and purchasing new supercomputers. The National competence centre is focusing it’s efforts primarily on building the supporting ecosystem and raising the adoption of HPC tools and connected technologies across all sectors. Without an available HPC infrastructure, however, this task remains a challenge.

Speakers' presentations:
How is Slovakia doing with supercomputing? – Lukáš Demovič.
HPC and numeric weather forecast in Slovakia -Jozef Vivoda.
Who can afford artificial intelligence today? – Mária Bieliková.
Is a supercomputer suitable only for science? – Robert Cisár.
2D semiconductor modeling by exascale computing methods – Ivan Štich.
The supercomputer is not just about computing power – Luboš Kolář.
Why do we need supercomputers? Discussion.

Computational power increased thanks to new technologies and innovations in semiconductor device fabrication and enabled doubling the number of components per integrated circuit every two years – this trend is described by the Moore’s law. However, we are now approaching physical limits in this area.

Another way of speeding up calculations is to use parallel approach, supported by today’s supercomputer architectures, including high-speed interconnecting network. Doc. Šperka described the history from the first parallel vector computers and Cray-1 supercomputer up to modern supercomputers.

Lecture series is a joint activity of the Computer museum COO SAS and National Competence Center for HPC. NCC, as the primary contact point for HPC in Slovakia, covers, among other things, educational and dissemination activities in this area.

There are a lot of HPC users in Slovakia that work with this type of applications and algorithms in their research. As one of the developers of chemical modelling methods Pavel also elaborated on his experience with effective software parallelization and described the main issues in the implementation. Although the computational cost of these methods is prohibitive for modelling larger systems, they are used for calibrating of other methods capable of describing and predicting properties of complex molecules, such as new drugs or materials.

Filip Holka, Head of the High-Performance Computing Department, and Lukáš Demovič, Director of COO SAS, took care of the introductory event Current trends and visions in HPC in Slovakia. In the first part, the participants learned how to define a supercomputer, on what technologies today's supercomputers are built, everything that must be taken into account in their design, as well as how to evaluate performance and energy efficiency. The second part of the lecture brought an interesting recapitulation of the history of HPC in Slovakia, but also a description of the current state and capacities in comparison with Europe and the surrounding countries. It is clear that Slovakia needs to invest in HPC infrastructure and support the digitization and use of innovative technologies, if it is to keep up with the rest of Europe. As Slovakia is a part of the European structures PRACE-RI and EuroHPC JU, we also touched on the benefits and opportunities that international cooperation brings to us and our users.

Last but not least, we also focused on initiatives that arose in Slovakia - specifically the National Supercomputing Center (NSCC), whose ambition is to develop HPC infrastructure and support high-performance computing in Slovakia.

The participants used the break with refreshments and coffee for informal conversations and discussions with the organizers and speakers.

National Competence Centre for HPC  organizes a series of lectures on why scientists need supercomputers and high-performance computing. This is a joint activity of the NCC and the Computer museum of the Centre of Operations, SAS.

Every user realizes that the use of HPC in various disciplines is a multidisciplinary issue. Not only is it necessary to have expertise in a specific scientific field, but further knowledge of modeling and simulation methods, programming basics, operating systems and computer architecture is required. The first lectures will therefore cover mostly HPC basics, preparing the participants for later presentations, in which experts from the SAS and the Slovak universities will speak in more detail about the use of HPC in various scientific disciplines. Our goal is to compensate to some extent what is often missing in the curricula of the universities and to try to deliver comprehensive information in the context of the global development.

The lectures are suitable for students, but also for people who want to learn more about HPC technologies, their development and utilization in science. Open, informal discussions with the invited speakers will be an important part of the events taking place in the SAS lecture hall within the Patrónka area.  It will also be possible to watch the lectures online via YouTube. Attendance is free, but all hygiene measures and rules in connection with the Covid-19 pandemic have to be observed. For in-person attendance it is also necessary to register on the website http://itkurzy.sav.sk/prednasky.
