Calcolo teorico e degli esperimenti

Presentazione orale

Active emulsions, droplets of liquid crystalline active matter encapsulating passive isotropic cores, represent a versatile and experimentally realisable class of topological active matter. Here, we present results from three-dimensional Lattice Boltzmann (LB) simulations of multiphase active nematic emulsions, developed and validated as part of the use case "Large Scale Simulations of Complex...

Calcolo teorico e degli esperimenti

Presentazione orale

The Compact Muon Solenoid (CMS) experiment at the CERN LHC has traditionally relied on a highly selective Level-1 trigger to reduce the 40 MHz LHC collision rate to a rate more manageable for data-reading and recording. During LHC Run 3, CMS deployed a novel 40 MHz data acquisition system that enables the continuous readout and real-time processing of L1 trigger-level detector data at the full...

Calcolo teorico e degli esperimenti

Presentazione orale

On behalf of the ALICE collaboration
The ALICE experiment has a long-standing expertise in GPU computing for high-energy physics, having used hardware accelerators since Run 2. With Run 3, ALICE changed its data acquisition model to triggerless mode, relying even more heavily on GPUs to handle the data throughput produced by continuous detector readout. During Pb-Pb collisions today, Alice...

184. Il modello di computing di KM3NeT

Emidio Maria Giorgio (Istituto Nazionale di Fisica Nucleare), Riccardo Bruno (Istituto Nazionale di Fisica Nucleare)

Calcolo teorico e degli esperimenti

Presentazione orale

The KM3NeT Collaboration is building a large-scale neutrino research infrastructure in the Mediterranean Sea, comprising the ARCA detector, in Italy, and the ORCA detector in France. Within this framework, INFN plays a central role in the computing and data management strategy supporting both detectors.

The Tier-0 facilities, hosted at the detector sites (Portopalo di Capo Passero for ARCA...

176. Multi-scale Geant4 simulations for BNCT applications

Dr Alessandro Colombi (Istituto Nazionale di Fisica Nucleare)

11/05/2026, 10:40

Calcolo teorico e degli esperimenti

Presentazione orale

The optimization of Boron Neutron Capture Therapy (BNCT) requires an accurate computational framework capable of integrating complex neutron source characterization with precise energy deposition modeling. In this context and within the activities of the Geant4INFN project, this work presents recent advances of Geant4 simulations, using the Multi-Threading (MT) architecture and exploiting both...

123. The QCD Equation of State from large scale HPC calculations

Matteo Bresciani (Trinity College Dublin)

11/05/2026, 11:30

Calcolo teorico e degli esperimenti

Presentazione orale

Quantum Chromodynamics (QCD) is the theory that describes the strong interactions among fundamental particles. Its highly complex dynamics cannot be solved analytically, and a predictive approach relies on numerical simulations in which space-time is discretized on a four-dimensional lattice and the theory is solved using Monte Carlo methods. These calculations are well suited for...

125. GPU-Accelerated Lattice QCD: Porting and Optimization

Francesca Margari (University and INFN of Roma Tor Vergata)

11/05/2026, 11:45

Calcolo teorico e degli esperimenti

Presentazione orale

In the last decade, advances in theoretical and algorithmic methods together with the growth of computational resources have made lattice QCD a key tool at the precision frontier of particle physics, enabling systematically improvable predictions for observables measured with increasing experimental accuracy. Within this context, we present the development of software for lattice QCD and...

126. Opportunistic Integration of the LHCb HLT2 Farm into the Distributed Computing

Calcolo teorico e degli esperimenti

Presentazione orale

The LHCb HLT2 Farm comprises ~4,500 nodes and ~260k CPU cores, primarily dedicated to real-time data processing. Extended idle periods during technical stops represent a significant, under exploited computing opportunity.
We present an HTCondor-based opportunistic computing model that integrates the HLT2 Farm into the LHCb distributed computing infrastructure while preserving strict priority...
