In this paper we present machine learning based technique to
estimate access patterns for grid datasets. We have analyzed 3-year
historical data of Kurchatov Institute Tier1 site and applied gradient
boosting algorithm to predict nearest future access patterns for the
dataset based on its previous access statistics. We show our method to
be effective for ATLAS data popularity...

All known approaches to parallel data processing in relational client-server database management systems are based only on inter-query parallelism. Nevertheless, it’s possible to achieve intra-query parallelism by consideration of a request structure and implementation of mathematical methods of parallel calculations for its equivalent transformation. This article presents an example of...

Many tens of petabytes of data from the CMS experiment at over a couple hundred sites around the world need to be managed. This represents more than an order of magnitude increase in data volume over HEP experiments in a pre-LHC era. The Physics Experiment Data Export (PhEDEx) project was chosen to fulfill this need. It deals with different storage systems, interacts with the CMS catalogues,...

Abstract. The purpose of this paper is to examine distributed databases and some problems of Grid dealing with the data replication from different points of view. This paper is referred to find out the most efficient commonalities between Data Grid and that managed data stored in object-oriented databases. We discuss about features of Distributed Database System (DDBS) such as, design,...

Many applied research of geography and oceanology require big data processing. One of these problems it is tsunami waves modeling. This task involves dynamic re-interpolation of bathymetry data on multiple grids of different scales. It is determined by the distance from the coastline and existence of islands along the front of wave. In this work re-interpolation is implemented by applying...

В мире наблюдается постоянный и устойчивый рост количества научных рецензируемых журналов и публикуемых в них статей. [1,2]. По оценкам некоторых авторов в мире издается порядка 1 млн. статей в год, что соответствует ежедневному выпуску порядка 2700 публикаций [2]. Хотя значительная часть такого рода ресурсов находится в электронных фондах (ЭФ), тщательно изучать такие информационные массивы...
