Data Analysis - Algorithms and Tools

Parallel Talk

Hadronic final states in hadron-hadron collisions are often studied by clustering final state hadrons into jets, each jet approximately corresponding to a hard parton. The typical jet size in a high energy hadron collision is between 0.4 and 1.0 in eta-phi. On the other hand, there may be structures of interest in an event that are of a different scale to the jet size. For example, to a...

The Compressed Baryonic Matter (CBM) experiment at the future FAIR facility at Darmstadt will measure dileptons emitted from the hot and dense phase in heavy-ion collisions. In case of an electron measurement, a high purity of identified electrons is required in order to suppress the background. Electron identification in CBM will be performed by a Ring Imaging Cherenkov (RICH) detector and...

Parallel Talk

A lot of code written for high-level data analysis has many similar properties, e.g. reading out the data of given input files, data selection, overlap removal of physical objects, calculation of basic physical quantities and the output of the analysis results. Because of this, too many times, writing a new piece of code, one starts copying and pasting from old code, modyfing it then for...

80. Parallel approach to online event reconstruction in the CBM experiment

Data Analysis - Algorithms and Tools

Parallel Talk

Future many-core CPU and GPU architectures require relevant changes in the traditional approach to data analysis. Massive hardware parallelism at the levels of cores, threads and vectors has to be adequately reflected in mathematical, numerical and programming optimization of the algorithms used for event reconstruction and analysis. An investigation of the Kalman filter, which is the core of...

78. FATRAS – A Novel Fast Track Simulation Engine for the ATLAS Experiment

Data Analysis - Algorithms and Tools

Parallel Talk

Monte Carlo simulation of the detector response is an inevitable part of any kind of analysis which is performed with data from the LHC experiments. These simulated data sets are needed with large statistics and high precision level, which makes their production a CPU-cost intensive task. ATLAS has thus concentrated on optimizing both full and fast detector simulation techniques to achieve...

5. Visual Physics Analysis - Applications in High-Energy- and Astroparticle-Physics

VISPA (Visual Physics Analysis) is a novel development environment to support physicists in prototyping, execution, and verification of data analysis of any complexity. The key idea of VISPA is developing physics analyses using a combination of graphical and textual programming. In VISPA, a multipurpose window provides visual tools to design and execute modular analyses, create analysis...
