The review of the distributed grid computing infrastructure for LHC experiments in Russia is given. emphasis placed on Tier-1 site construction at National Research Centre "Kurchatov Institute" (Moscow) and Joint Institute Nuclear (Dubna).
Simulation of the water flow around a ship hull and marine propeller operation are considered in this paper as popular problems propulsion, which frequently investigated through CFD approach now. technologies used for determination resistance well open curves according to usual methods design. FlowVision software is simulations based on solving RANS equations. The was together with supercomputer "HPC 2" National Research Center "Kurchatov Institute". original features numerical models...
The PanDA (Production and Distributed Analysis) workload management system (WMS) was developed to meet the scale complexity of LHC distributed computing for ATLAS experiment. currently distributes jobs among more than 100,000 cores at well over 120 Grid sites, supercomputing centers, commercial academic clouds. physicists submit 1.5 M data processing, simulation analysis per day, keeps all meta-information about job submissions execution events in Oracle RDBMS. above information is used...
In recent years the concepts of Big Data became well established in IT. Systems managing large data volumes produce metadata that describe and workflows. These are used to obtain information about current system state for statistical trend analysis processes these systems drive. Over time amount stored can grow dramatically. this article we present our studies demonstrate how storage scalability performance be improved by using hybrid RDBMS/NoSQL architecture.
Large-scale scientific experiments produce vast volumes of data. These data are stored, processed and analyzed in a distributed computing environment. The life cycle experiment is managed by specialized software like Distributed Data Management Workload Systems. In order to be interpreted mined, experimental must accompanied auxiliary metadata, which recorded at each processing step. Metadata describes represent objects or results experiments, allowing them shared various applications,...
Rapid increase of data volume from the experiments running at Large Hadron Collider (LHC) prompted physics computing community to evaluate new handling and processing solutions. Russian grid sites universities' clusters scattered over a large area aim task uniting their resources for future productive work, same time giving an opportunity support collaborations. In our project we address fundamental problem designing architecture integrate distributed storage LHC other data-intensive science...
Paper presents some results of the implementation a quasi-hydrodynamic (QHD) approach as finite volume method (FVM) solver mulesQHDFoam on basis OpenFOAM. Application QHD numerical algorithm to simulation attractor internal gravity waves is considered. A comparison FVM with spectral element (SEM) implemented in Nek5000 given. Convergence model SEM shown. The Big Data analysis (Proper Orthogonal Decomposition) used tool for comparing calculation between QHDFoam and Nek5000.
The LHC experiments are preparing for the precision measurements and further discoveries that will be made possible by higher energies from April 2015 (LHC Run2). need simulation, data processing analysis would overwhelm expected capacity of grid infrastructure computing facilities deployed Worldwide Computing Grid (WLCG). To meet this challenge integration opportunistic resources into model is highly important. Tier-1 facility at Kurchatov Institute (NRC-KI) in Moscow a part WLCG it...
There is pronounced interest to cloud computing in the scientific community. However, current offerings are rarely suitable for highperformance computing, large part due an overhead level of underlying virtualization components. The purpose this paper propose a design and implementation system that possesses small enough allow it be practically used wide range workloads. First, we describe requirements desired classify workloads identify those practical transfer cloud. Then, review related...
Creation of global e-Infrastructure involves an integration isolated local resources into common heterogeneous computing environment. In 2014 a pioneering work to develop large scale data- and task- management system for federated has been started at the National Research Centre "Kurchatov Institute" (NRC KI, Moscow). As part this work, we have designed, developed deployed portal submit payloads infrastructure. It combines Tier-1, Cloud-infrastructure, supercomputer Kurchatov institute. This...
