EOSC-hub - Integrating and managing services for the European Open Science Cloud (EOSC-hub)
Integrovanie a manažment služieb pre európsky cloud pre otvorenú vedu
Program: Horizont 2020
Project leader: doc. Ing. Hluchý Ladislav CSc.
Annotation:The EOSC-hub project creates the integration and management system of the future European Open Science Cloud that delivers a catalogue of services, software and data from the EGI Federation, EUDAT CDI, INDIGO-DataCloud and major research e-infrastructures. This integration and management system (the Hub) builds on mature processes, policies and tools from the leading European federated e-Infrastructures to cover the whole life-cycle of services, from planning to delivery. The Hub aggregates services from local, regional and national e-Infrastructures in Europe, Africa, Asia, Canada and South America. The Hub acts as a single contact point for researchers and innovators to discover, access, use and reuse a broad spectrum of resources for advanced data-driven research. Through the virtual access mechanism, more scientific communities and users have access to services supporting their scientific discovery and collaboration across disciplinary and geographical boundaries. The project also improves skills and knowledge among researchers and service operators by delivering specialised trainings and by establishing competence centres to co-create solutions with the users. In the area of engagement with the private sector, the project creates a Joint Digital Innovation Hub that stimulates an ecosystem of industry/SMEs, service providers and researchers to support business pilots, market take-up and commercial boost strategies. EOSC-hub builds on existing technology already at TRL 8 and addresses the need for interoperability by promoting the adoption of open standards and protocols. By mobilizing e-Infrastructures comprising more than 300 data centres worldwide and 18 pan-European infrastructures, this project is a ground-breaking milestone for the implementation of the European Open Science Cloud.

An individual stimulating system with 3D nano-structure carbon/graphene based transducer and wireless heater for automated tiny insects behavior monitoring
Monitorovací a stimulačný systém s 3D snímačom a mikro-ohrievačom na báze uhlíka/grafénu s bezdrôtovým ovládaním pre automatizované individuálne monitorovanie a stimuláciu drobného hmyzu
Program: JRP
Project leader: Ing. Mgr. Andok Robert PhD.
Annotation:This project is a collaboration project with the Department of Power Mechanical Engineering, National Tsing Hua University in Taiwan (NTHU). In this project, a system that could monitor and analyze insect behavior will be developed. Such system can detect the position of the insect and stimulate insects individually in real-time. Generally, this project is divided into three parts: 1. Designing and manufacturing a 3D micro transducer. 2. Designing and manufacturing an individual stimulator made by the wireless heater. 3. Designing a monitoring and analysis system that could observe the behavior of tiny insects systematically. The parameters of the experimental setup are designed based on the characteristics of the Drosophila organism model (made at NTHU), which can also be used on other tiny insects. The nearly negligible weight and size of the insects is what makes them hard to locate in real-time. By using the electron beam lithography and reactive-ion etching equipment that II SAS provides, a micro bridge structure will be developed. After that, 3D nano carbon/graphene material will be grown onto the structure and the resulting device is a highly sensitive micro transducer that can measure small increments in weight. By placing such transducers all around the experimental platform, the precise position of the insects can be monitored. A wireless heater is installed on to the body of the insects to stimulate them individually under certain circumstances. This heater is made by connecting a nanometric diamond film with a high density micro coil produced at II SAS. By exerting electromagnetic waves of certain frequency (this frequency is related to the size of the coil), electromagnetic induction will occur and the device will heat up stimulating the insect. By using the two devices mentioned above, together with a camera, image processing algorithms, and other hardware equipment, such as a camera stand and a container to place the flies, a system that is used to observe the behavior of small insects, will be developed. The capability of stimulating individual insects and tracking them simultaneously brings up new possibilities of designing more complicating experiments regarding the social behavior of insects. It is the experience of dealing with living organisms and the techniques of manufacturing nano-scale structures that both parties will exchang with each other that can make the development of this system such successful. From this collaboration between II SAS and NTHU more novel nanoscale devices are expected in near future. Drosophilas are commonly used in this project as a model organism. The hierarchical structure of their brains resembles the brain of a mammal, which constitutes to their complicated social behavior. As a broader impact of the results of this bilateral cooperation, by observing the social behavior of these flies, insight on typical human brain disorders (such as the Parkinson’s, the Alzheimer’s, and the Huntington’s disease), neural networks, and biological evolution could be gained. Therefore, the results of this project may also affect wider areas of research, including life and medical sciences.

DEEP-HybridDataC - Designing and Enabling E-infrastructures for intensive Processing in a Hybrid DataCloud (DEEP-HybridDataCloud)
Návrh a sprístupnenie e-infraštruktúr pre intenzívne spracovanie v hybridnom dátovom cloude
Program: Horizont 2020
Project leader: doc. Ing. Hluchý Ladislav CSc.
Annotation:The key concept proposed in the DEEP Hybrid DataCloud project is the need to support intensive computing techniques that require specialized HPC hardware, like GPUs or low latency interconnects, to explore very large datasets. A Hybrid Cloud approach enables the access to such resources that are not easily reachable by the researchers at the scale needed in the current EU e-infrastructure. We also propose to deploy under the common label of “DEEP as a Service” a set of building blocks that enable the easy development of applications requiring these techniques: deep learning using neural networks, parallel post-processing of very large data, and analysis of massive online data streams. Three pilot applications exploiting very large datasets in Biology, Physics and Network Security are proposed, and further pilots for dissemination into other areas like Medicine, Earth Observation, Astrophysics, and Citizen Science will be supported in a testbed with significant HPC resources, including latest generation GPUs, to evaluate the performance and scalability of the solutions. A DevOps approach will be implemented to provide the chain to ensure the quality of the software and services released, that will also be offered to the developers of research applications. The project will evolve to TRL8 existing services and technologies at TRL6+, including relevant contributions to the EOSC by the INDIGO-DataCloud H2020 project, that the project will enrich with new functionalities already available as prototypes, notably the support for GPUs and low latency interconnects. These services will be deployed in the project testbed, offered to the research communities linked to the project through pilot applications, and integrated under the EOSC framework, where they can be further scaled up in the future.

SAV-NASU2017-201 - Development of software tools for analysis and synthesis of schedulers for cloud computing
Návrh softvérových nástrojov pre analýzu a syntézu plánovačov pre počítanie v cloude
Program: Medziakademická dohoda (MAD)
Project leader: doc. Ing. Hluchý Ladislav CSc.
Annotation:Modern scientific problems require significant computing resources, so the problem of resources optimization in multiprocessor environments is very important. We will focus on cloud systems as one of the most recent and promising fields of high-performance computing. Cloud computing systems operate in complex heterogeneous environments. It is common to have a single physical server with many simultaneous programs from different users competing for computing and network resources. In most cases, especially for public cloud, the user is unable to control the distribution of resources. The allocation algorithms may contain defects and inefficiency and this can lead to a significant increase in processing time, that is why cloud computing require efficient algorithms providing flexible and stable allocation of resources. The problem is in unfair and uneven access to resources, caused by heterogeneity of users and their tasks where each user is rational agent that tries to increase its share of resources. This could bring the system to the inefficient equilibrium., so a key element of cloud systems are efficient algorithms for load distribution – schedulers and brokers, providing services to users. The idea of this project is to apply game-theoretic approach to the problem of scheduling and allocation of computing resources in dynamic heterogeneous environment with many competitive users and provide software tools based on game-theoretic construction. Another idea of the project is an optimization approach that respects the requirements of end-users. This task will be modelled as a multi-criteria optimization problem. Each objective of the optimization will be associated with a weight. The weight will express the priority of the optimization objective. This way of the optimization will enable the end-users to adjust it to their needs. The problem will be sorted out in a general way so the solution will support various cloud providers. The project continues the previous cooperation of our Institute in constructing adaptive methods for programming high-performance computing on heterogeneous multiprocessor systems.

PROCESS - PROviding Computing solutions for ExaScale ChallengeS (PROCESS)
Poskytovanie výpočtových riešení pre výzvy v oblasti ExaScale
Program: Horizont 2020
Project leader: doc. Ing. Hluchý Ladislav CSc.
Annotation:The PROCESS demonstrators will pave the way towards exascale data services that will accelerate innovation and maximise the benefits of these emerging data solutions. The main tangible outputs of PROCESS are five very large data service prototypes, implemented using a mature, modular, generalizable open source solution for user friendly exascale data. The services will be thoroughly validated in real-world settings, both in scientific research and in industry pilot deployments. To achieve these ambitious objectives, the project consortium brings together the key players in the new data-driven ecosystem: top-level HPC and big data centres, communities – such as Square Kilometre Array (SKA) project – with unique data challenges that the current solutions are unable to meet and experienced e-Infrastructure solution providers with an extensive track record of rapid application development. In addition to providing the service prototypes that can cope with very large data, PROCESS addresses the work programme goals by using the tools and services with heterogeneous use cases, including medical informatics, airline revenue management and open data for global disaster risk reduction. This diversity of user communities ensures that in addition to supporting communities that push the envelope, the solutions will also ease the learning curve for broadest possible range of user communities. In addition, the chosen open source strategy maximises the potential for uptake and reuse, together with mature software engineering practices that minimise the efforts needed to set up and maintain services based on the PROCESS software releases.

Algorithm of collective intelligence: Interdisciplinary study of swarming behaviour in bats
Algoritmus kolektívnej inteligencie: Interdisciplinárne štúdium swarmového správania netopierov.
Program: APVV
Project leader: Ing. Budinská Ivana PhD.
Annotation:Various algorithms of artificial intelligence inspired by real biological mechanisms are successfully applied in military and civil sector. In this proposed project, cooperative research of four scientific institutions having different basis, methodology and the object of study (biology, computer science and technology) focuses on interdisciplinary study of social self-organizational behaviour of tree-dwelling bats with the aim to develop new meta-heuristic method capable of space exploration. The project has a great potential to bring new scientific knowledge about mechanisms of collective intelligence in social structures of biological organisms, which will contribute to the field of theoretical biology, behavioural nad evolutionary ecology. Additionally, it will contribute to the field of artificial intelligence as it focuses on swarming behaviour of individuals/agents with higher nervous activity and well developed cognitive skills. The model organisms (bats) on which this project is focused are using advanced biological mechanism capable of state space exploration and at the same time preventing group disintegration. This specific characteristic has a great potential for development of new biologically inspired algorithms and methods applicable e.g. in movement coordination of unmanned aerial vehicles. Distinguished contribution of the project is R&D of ultra-light sensors applicable not only in biological research. The project originality is in interconnection of different research areas. Therefore it is important to review it interdisciplinary.

Automatic assessment of acute stress from speech.
Automatické hodnotenie akútneho stresu z reči
Program: VEGA
Project leader: Ing. Rusko Milan PhD.
Annotation:A person often intuitively identifies whether his/her partner in conversation is under stress, just from stress manifestations in the voice and speech. However, the group of acute stress manifestations and their measurable acoustic cues are not known well. There are no suitable speech databases available to study these manifestations. We will design an experimental scenario when the subject is stressed and is forced to communicate intensely via speech. During the experiment other modes, such as video, biosignals (pulse, skin conductivity, ...), will be recorded in addition to speech. We will analyze the collected data and propose an annotation scheme to capture the occurrence of stress. We will investigate the effects of stress and their acoustic correlates and select a set of acoustic features and a suitable machine learning method for automatically identifying stress in speech. A system for stress detection from speech will be developed and its results will be compared to subjective expert judgment.

Project leader: Ing. Mgr. Andok Robert PhD.
Annotation:Motivation of this project comes out the research of new 2D materials such as metal sulfides and from the present state of development of e-beam lithography (EBL) as one of the alternative methods of 2D structures preparation in electronics. This project is focused on obtaining new scientific results in the patterning of nano-scale structures (10-100nm) in electron resists. Attention will be paid to the research of the influence of the electron lithography processes on the resulting nanometric patterns patterned in electron resits in term of resolution, dimensions accuracy and edge roughness of the structures in the resist. We will study the parameters influencing the profile of the nanometric patterns in polymeric resists. The simulations of lithographic parameters of electron resists on thin semiconductor layers, nitride membranes and layers with 2D materials, are an important part of this project. Based on the simulations of lithographic parameters, we will prepare nanometric structures on these materials.

U-COMP - Urgent Computing for Exascale Data (U-COMP)
Urgentné počítanie pre Exascale dáta
Program: APVV
Project leader: doc. Ing. Hluchý Ladislav CSc.
Annotation:Current challenges of the European research area in computer science place emphasis on integration of research infrastructures, move to e-services, open access to data and reusability of services, data and research results. Furthermore, European infrastructures now move toward processing of Big Data and even exascale data, using novel modes of HPC such as urgent computing. The ability to use exascale systems to provide urgent decision making support critically depends on the ability of the supercomputing centers to provide urgent computing as a new use mode. We strongly believe that urgent computing must be a service provided by the future European computing centers. This will have the dual benefits of immediate delivery of societal benefits of the best performing (at any given time) systems, combined with their ability to optimize the design of the future operational centers with urgent computing capability. These challenges are best tackled by merging web services as the premier e-service paradigm, semantic web technologies for ease of data discovery and cloud computing as a flexible deployment platform. We would like to help to further our understanding of the e-service composition and orchestration challenges when done on a massive scale, and to allow the operators and users of e-services to truly enter the era of Cloud Computing by providing methodology, architecture, tools and standards which will make it easier, safer, and also less expensive to adopt true Cloud Computing and distributed service-oriented applications en masse. Thus we have chosen four research domains which we want to target in this proposal: • composition and orchestration of e-service processes with support of urgent computing; • use of semantic web technologies in describing the services and domain components of the processes; • interoperability of cloud environments and HPC resources and their compatibility with urgent computing; • scalable and distributed aggregation and analysis of data
