Access is guaranteed within two weeks of the application deadline (application deadlines are usually set once a month). The evaluation of submitted projects will take place on a fixed date at monthly intervals. The objectives of the individual modes of access within this proposal are:
Benchmark calls are designed for code scalability tests, the outcome of which is to be included in the proposal in a future EuroHPC Extreme Scale and Regular call. Users receive a limited number of node hours; the maximum allocation period is three (3) months.
Development calls are designed for projects focusing on code and algorithm development and optimisation. This can be in the context of research projects from academia or industry, or as part of large public or private funded initiatives as for instance Centres of Excellence or Competence Centres. Users will typically be allocated a small number of node hours; the allocation period is one (1) year and is renewable up to 2 times.
Various systems will be available in each cut-off for the different Benchmark & Development Access modes. The exact amount of available node hours is subject to the EuroHPC systems participating in a given call and will be announced prior to the cut-off dates. For the first cut-off period the VEGA system resources (Slovenia) are available.
10. novembra 2021 sa uskutočnila už štvrtá prednáška série Superpočítanie vo vede. Tentokrát sme privítali Dr. Dušana Bernáta z Fakulty matematiky, fyziky a informatiky Univerzity Komenského so zaujímavou prednáškou na tému Operačné systémy v multiprocesorových klastroch.
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.
Obr. 1: Diagram stavu procesov
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.
Obr. 2: Symetrický multiprocesorový systém
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:
Obr. 3: Ukážka 4 procesorového point-to-point prepojenia, konfigurácie typickej pre NUMA
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.

Join us to talk about supercomputing in science in an informal atmosphere with coffee and refreshments! We have prepared a series of interesting lectures on high-performance computing – there is no registration fee, but the registration is required.
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.
We are very pleased that our invitation was accepted by interesting speakers and we are looking forward to inspiring lectures and stimulating discussions in a relaxed atmosphere with coffee and refreshments!
