A substantial data volume growth will appear with the start of the HL-LHC era. It is not well covered by the current LHC computing model, even taking into account the hardware evolution. The WLCG DOMA project was established to provide data management and storage researches. National data lake r&d's, as a part of the DOMA project, should address the study of possible technology solutions for...
The research of load balancing strategies in Grid systems is carried out. The main classes of load distribution strategies are identified with the aim of possibly increasing the efficiency of distributed systems. A model based on the fractal method for describing the dynamics of the load is considered.
The model of Russian Remote Participation Center (RPC) was created under the contract between Russian Federation Domestic Agency (RF DA) and ROSATOM as the prototype of full-scale Remote Participation Center for ITER experiments and for coordination activities in the field of Russian thermonuclear research. This prototype was used for investigation of the following technical and scientific...
Abstract. The questions of constructing optimal logical structure of a distributed database (DDB) are considered. Solving these issues will make it possible to increase the speed of processing requests in DDB in comparison with a traditional database. In particular, such tasks arise for the organization of systems for processing huge amounts of information from the Large Hadron Collider the...
The CREST project for a new conditions database prototype for Run3 (intended to be used for production in Run 4) is focused on improvement of Athena based access, metadata management and, in particular, global tag management. The project addresses evolution of the data storage design and conditions data access optimization, enhancing the caching capabilities of the system in the context of...
Processing and analyzing of experimental and simulated data are an integral part of all modern high-energy physics experiments. These tasks are of particular importance in the experiments of the NICA project at the Joint Institute for Nuclear Research (JINR) due to the high interaction rate and particle multiplicity of ion collision events, therefore the task of automating the considered...
Particle collision experiments are known to generate substantial amount of data that must be stored and, later, analyzed. Typically, only a small subset of all the collected events is relevant when performing a particular physics analysis task. Although it is possible to obtain the required subset of records directly, by iterating through the whole volume of the collected data, the process is...
The Multifunctional Information and Computing Complex in the Laboratory of Information Technologies of the Joint Institute for Nuclear Research is a multicomponent hardware and software complex, which ensures the fulfillment of a wide range of tasks related to the processing, analysis and storage of data in research conducted at the world level at JINR and in the world centers collaborating...
The report presents a solution for completely decentralized data management systems in geographically distributed environments with administratively unrelated or loosely related user groups and in conditions of partial or complete lack of trust between them. The solution is based on the integration of blockchain technology, smart contracts and provenance metadata driven data management....
The Data Knowledge Base (DKB) project is aimed at knowledge acquisition and metadata integration, providing fast response for a variety of complicated queries, such as summary reports and monitoring tasks (aggregation queries) and multi-system join queries, which are not easy to implement in a timely manner and, obviously, are less efficient than a query to a single system with integrated...
The medical field, and especially diagnosis, is still an extremely poorly formalized field. This is especially true in the study of diseases associated with changes and disorders in the activity of the brain. In order to improve the results of medical research in this area, various methods of analyzing the condition of patients are used. These include both instrumental methods (MRI, EEG) and...
The problems of silent data corruption detection in the data storage systems (Reed-Solomon codes) and faulty share detection in the distributed voting protocols (Shamir scheme) are treated from a uniform point of view. Namely, the both can be interpreted as the problem of systematic error detection in the data set { (x_1, y_1),...(x_N,y_N)} generated by a polynomial function y=f(x) in some...
Nowadays, the problem of identification and authentication on the Internet is more urgent than ever. There are several reasons for this: on the one hand, there are many Internet services that keep records of users and differentiate their access rights to certain resources; on the other hand, cybercriminals' attacks on web services have become much more frequent lately. At the same time, in...
The article discusses the main provisions (methods, risk models, calculation algorithms, etc.) of the issue of organizing the protection of personal data (PD), based on the application of anonymization procedure. The authors reveal the relevance of the studied problem based on the tendency of the general growth of informatization and the further development of the Big Data technology. This...
The process of digitalization of the Russian economy as the basis for the transition to the digital economy is conditioned by the requirements of objective reality and is based, first of all, on the introduction of digital technologies into the activities of its actors. The most promising is the Blockchain technology, which has the capabilities of the most effective coordination of the...
