Operation systems in multiprocessor clusters

Operačné systémy v multiprocesorových klastroch

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.

NCC Slovakia at the ITAPA 2021 congress

NCC Slovakia at the ITAPA 2021 congress

On November 9th, 2021 the second day of the ITAPA congress took place featuring several contributions focused on high-performance computing as an important tool for enabling innovations, ensuring the competitiveness of economies as well as for supporting security and scientific research. The Slovak National Competence Centre for HPC in collaboration with the congress organizers invited Mr. Gustav Kalbe as one of the keynote speakers. As a representative of the EuroHPC JU he covered this topic from the global and European point of view.

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 CoE showed 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 institute, their 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 sa usiluje predovšetkým o vybudovanie podporného ekosystému a o zvýšenie adopcie HPC nástrojov a súvisiacich technológií naprieč všetkými sektormi. Bez dostupnej a výkonnej infraštruktúry je však naša úloha mimoriadne náročná.

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.

Development of technology and computer architecture – from 1-processor serial computers to supercomputers

Development of technology and computer architecture – from 1-processor serial computers to supercomputers

On October 26, 2021 the third lecture of our „Supercomputing in science“ series took place on the premises of the Computational centre of the Slovak Academy of Sciences  Doc. Šperka, who is also responsible for the Computer museum, showed development of computer architectures and it’s components, such as CPU, GPU and RAM.

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.

Current trends and visions in HPC in Slovakia

Current trends and visions in HPC in Slovakia

On September 29, we started a series of lectures "Supercomputing in Science" in the lecture hall of the Slovak Academy of Sciences  Popularization-educational lectures are a joint activity of the Computer Museum and the 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.

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.

Supercomputing in science - starting soon!

Supercomputing in science - starting soon!

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 Center 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!

The National competence centre launches a nation-wide HPC survey

The National competence centre launches a nation-wide HPC survey

The national competence centre for HPC is launching a nation-wide survey of competencies and requirements in the field of high-performance computing and the usage of HPC+ solutions. Information gained through this survey will help the competence centre to create effective strategies for concrete support and services for private companies, academia and public administration.

The primary goal of the survey is to map the usage of HPC and associated technologies and to identify the demand for these technologies and solutions among Slovak private companies, small and medium enterprises, academic research groups and in public administration. This information is crucial for developing strategies, goals and services for the future National competence centre activities. According to the OECD publication SME Entrepreneurship Policy in Slovak Republic“*   the SMEs are facing several barriers in their digital transformation, such as lack of knowledge and experience. The National competence centre enables the knowledge transfer and adoption of HPC, HPDA, AI and ML technologies, where the benefits for private companies include competitive advantage on the market, effective processes, ROI and cost savings.

“Apart from these activities the National competence centre has an ambition to facilitate the collaboration between experts and end-users coming from various areas and sectors. This survey will help us to identify experts in specific application fields, such as processing big data, advanced simulations and machine learning/artificial intelligence technologies.”  the coordinator of the project, Lucia Demovičová, stated.

The survey will also provide information about the computational capacities and resources required at the moment and into the future in Slovakia. Actual local data from Slovak HPC users, including the potential future ones, will be valuable in planning the new high-performance systems and developing the national HPC infrastructure.

The NCC was established within the EuroCC project implemented by the Centre of Operations of the Slovak Academy of Sciences. As a primary contact point for users and all parties interested in HPC in Slovakia the NCC provides several services free of charge that might be interesting for scientific teams, but also the private sector and public administration. Education activities, consultancy and access to computational resources are among the portfolio of NCC services that are meant to support the innovation potential and competitiveness in Slovakia.

Public procurement of a new supercomputer

Public procurement of a new supercomputer

The Cente of Operations, Slovak Academy of Sciences has started a public procurement process to purchase a new supercomputer for the National competence centre for HPC. Research and development experts from academia and also the public and private sectors will take advantage of the new computational capacities.  

The access policy will be directed solely by the COO SAS. The new supercomputer will be accessible to academic groups, public sector organizations and also small and medium enterprises (SMEs).

Information and further details concerning the procurement were published via the tenders electronic daily portal, a supplement of the Official Journal of the EU (30.7.2021) and the  Journal of the Office for Public Procurement (2.8.2021). After the 60 day period for the tender submissions and the subsequent evaluation the whole process will be reviewed by the Ministry of Investments, Regional Development and Informatization of the Slovak Republic and the Office for Public procurement. The new supercomputer should be operational in the first half of the 2022.

The project National Competence Centre for High-Performance Computing (ITMS2014+ 311071AKF2) is financed through the Operational programme Integrated Infrastructure: OPII-2020/7/55-NP. One of the goals of this project is to support Slovak enterprises, especially the SMEs and to raise their innovation potential. This will be achieved by creating a platform for effective adoption of the HPC+ technologies, which is in alignment with the Slovak strategy for digital transformation. The EU Structural Funds will be used for procurement of a new HPC system, thus providing technical support and basis of the National competence centre.
