Data Analysis - Algorithms and Tools
Plenary
The discovery of the Higgs boson by the ATLAS and CMS is the result of an elaborate statistical analysis of many signal and control samples for which a set of common tools has been used that were specially developed for the LHC. The key feature of this tool design has been a logical and practical separation between model building, the formulation of the likelihood function, and the statistical...

Distributed file systems provide a fundamental abstraction to location-transparent, permanent storage. They allow distributed processes to co-operate on hierarchically organized data beyond the life-time of each individual process. The great power of the file system interface lies in the fact that applications do not need to be modified in order to use distributed storage. On the other...

Computations in Theoretical Physics: Techniques and Methods
Plenary
In this article we will discuss the basic calculational concepts to simulate particle physics events at high energy colliders. We will mainly focus on the physics in hadron colliders and particularly on the simulation of the perturbative parts, where we will in turn focus on the next-to-leading order QCD corrections.

The Large Hadron Collider (LHC), operating at the international CERN Laboratory in Geneva, Switzerland, is leading Big Data driven scientific explorations. Experiments at the LHC explore the fundamental nature of matter and the basic forces that shape our universe, and were recently credited for the discovery of a Higgs boson. ATLAS, one of the largest collaborations ever assembled in the...

Plenary
Performance and scaling of many algorithms in scientific and distributed computing crucially depend on the memory model, organization and speed of access to the memory hierarchy. We will review parallel computing strategies and memory models in modern HPC, discuss MPI and OpenMP parallelization paradigms, as well as hybrid programming approach and memory mismatch problem. We will comment on...

The dark matter is undoubtedly one of the greatest enigmas of the modern physics. Its another mysterious companion in the energy budget of the universe, the dark energy, remains fully unexplained, but the dark matter recently started to reveal its secrets. During last years we have marked several important observations in the area of a direct detection based on the particle physics methods,...

Data Analysis - Algorithms and Tools
Plenary
Particle transport Monte Carlo simulation has a fundamental role in High Energy and Nuclear Physics (HENP) experiments. It enables an experiment's designers to predict its measurement potential, and to disentangle detector effects from the physics signal.
High-energy physics detector simulation is increasingly relied upon due to the increasing complexity of the experimental setups, which...

Modern software applications rarely live in isolation and nowadays it is common practice to rely on services or consume information provided by remote entities. In such a distributed architecture, integration is key.
Messaging, for more than a decade, is the reference solution to tackle challenges of a distributed nature, such as network unreliability, strong-coupling of producers and...

Data Analysis - Algorithms and Tools
Plenary
Many fields of science have developed multi-scale multi-component models to address large-scale heterogenous data sets. Constraining model parameters is made difficult by the inherent numerical cost of running such models and by the intertwining dependencies between parameters and observables. I will describe how the MADAI Collaboration has developed a suite of statistical tools based on the...

The future and limits of computing in physics are largely dependent on the
ever changing capabilities of the contemporary supercomputers. In this
contribution, we focus on current and near future computer architectures,
their limits and capabilities, in context of scientific computations.
Further we discuss trends in high performance computing and their impact on
the physics codes. The...

In the late 1990s, (mostly) economic reasons led to the adoption of commodity desktop processors in high-performance computing. This transformation has been so effective that in 2014 the TOP500 list is still dominated by x86-based computers.
More recently, around 2005-2008, always for economic/market reasons commodity GPUs became interesting and powerful enough devices to be used as...

After the discovery of the Higgs boson
- the last important building block of the Standard Model (SM)
required by its renormalizability - and the still missing
direct detection of new physics beyond SM at the LHC, the
self-consistency of the SM has attracted a lot of notice.
One of the approaches to determine the scale at which SM may break down
is based on the renormalization group (RG)...

Data Analysis - Algorithms and Tools
Plenary
Extensive use of multivariate techniques has allowed the HEP
experiments to improve the information content extracted from their
data. This affected both the event reconstruction from the detector
response as well as the selection process along a given physics
signature. While in many aspects at the forefront of technology,
modern statistical analysis tools have only slowly moved from...
