“INFN-Tier1 at CNAF: Status and future prospects”
Abstract:
“In this talk we will present CNAF, the national center of
INFN (Italian Institute for Nuclear Physics) “for the Research and
Development in INFN Information and Communication Technologies”. Being
the central computing facility of INFN, CNAF is engaged with many
initiatives at European and Worldwide level dealing with
e-infrastructures and scientific computing. Since 2003, CNAF hosts the
Italian Tier-1 for the high-energy physics experiments at the Large
Hadron Collider in Geneva, providing the resources, support and services
needed for all the activities of data storage and distribution, data
processing and analysis. CNAF is also supporting many astroparticles and
astrophysical experiments and to face the challenges of the most
demanding, extreme scale next generation scientific experiments, CNAF is
planning to expand its infrastructures. In the talk we will anticipate
some of these plans.”

“Numerical Simulations of the SPD NICA Setup”
Abstract: A review of magnetic system calculations for the SPD setup is given. Three basic model classes are considered: solenoidal, toroidal and hybrid. Various magnetic system configurations are discussed for each of the three above -mentioned models. Values of the main parameters are reported for each configuration. Based on the obtained results, the main advantages and disadvantages of the three model classed are discussed.

V. Palichik, A. Shishkin (St.Petersburg State University), N. VoytishinН.Н. :«Precise Coordinate Reconstruction in the Cathode Strip Chambers of the CMS Experiment» Abstract: The Run2 of the Large Hadron Collider (LHC) that we are facing now is characterized with a higher luminosity, pile-up and energy of the passing particles. This imposes new challenges almost to every part of all the systems that form the CMS experiment. The Cathode Strip Chambers (CSCs) are one of these parts. The strip coordinate on aparticular layer of a CSC is reconstructed with аbad accuracy (30-60% of strip width while the required precision is1-3%) in cases of high multiplicity of firedstrips. This is due to the fact that for a cluster that is formed out of overlapping signals a simple Center of Gravity (CoG) approach is used for coordinate reconstruction by the standard procedure. The development of a new wavelet-based reconstruction algorithm for the strip coordinate was initiated in order to improve its precision. Comparison results of the two algorithms are shown along with visualization of particular Monte-Carlo event examples.

“Robotized IT of data processing and intelligent control over physical installations on the basis of relativistic quantum informatics”
Abstract:
The developed structure of a self-organizing intelligent control systems allows one to include into its control loop a human factor on the basis of a hybrid cognitive control and to form the databases taking into account the contingencies of management. The methodology of the quantum relativistic informatics allows one, in general form on the basis of quantum programming, to develop an algorithmic software of the embedded intelligent controllers in distributed computing systems with a grid-infrastructure as well as to generate model representations of physical theories on the basis of information extracted from big unstructured data processing. Examples of some applications of the developed approach on real physical objects are presented.

“The Web access for the raw data event dump monitoring and the extension of Web application features for log data analysis of ATLAS Trigger/DAQ”
Abstract:
The Web service development for the access to the ATLAS data and to the detector operational data monitoring system became one of the important trends of system feature improvements after starting the exploitation of the ATLAS detector in the follow-up upgrades. The presentation considers two remote monitoring packages: Webemon and ERS Browser. Webemon implements the remote access to the raw data monitoring service. The user receives raw data events in the parsed XML format view that is ready for the integrity and correctness verification. The second package (ERS Browser) is intended to be used for online viewing and browsing the log data collected and stored by Error Reporting system. The Webemon was written in Python, ERS Browser was implemented with Splunk framework tools.
