I review the main aspects of QFT calculations, which affect many fields from HEP phenomenology, cosmology and gravitation. After an overview on amplitudes and Feynman Integrals, I will focus on the computational methods applied in the state-of-the-art results of our field, such as IBPs, tensor reduction, Differential equations, direct integration.
They make use of both symbolical and...
ALICE has upgraded its computing infrastructure and software to accommodate the increased data rates and enhanced detector performance in Run 3. This upgrade has also resulted in a significant reduction in energy consumption and CO₂ emissions, achieved through a combination of optimized resource utilization and the adoption of energy-efficient technologies. Key strategies include maximizing...
The Jiangmen Underground Neutrino Observatory (JUNO) is a 20 kton liquid scintillator detector being constructed underground in southern China. The JUNO physics program aims to explore neutrino properties, particularly through electron anti-neutrinos emitted from two nuclear power complexes at a baseline of approximately 53 km. Targeting an unprecedented relative energy resolution of 3% at 1...
UrgentShake è un sistema di urgent computing per la generazione rapida di scenari di scuotimento sismico basati su simulazioni fisiche. Il suo sviluppo è supportato dalle risorse di calcolo ad alte prestazioni (HPC) del progetto PNRR TeRABIT (Terabit Network for Research and Academic Big Data in Italy). L’architettura computazionale di UrgentShake sfrutta infrastrutture HPC e cloud distribuite...
Plasma accelerators can enable accelerator based applications at the university campus or large hospital level thanks to their reduced footprint and relatively low acquisition and operation costs. The underlying physical processes are described by the Vlasov-Maxwell equations coupled to the Lorentz force equation, so that their design requires solving a system of highly non-linear, partial...
The availability of high-dimensional transcriptomic datasets is increasing at a tremendous pace, together with the need for suitable computational tools. Clustering and dimensionality reduction methods are popular go-to methods to identify basic structures in these datasets. At the same time, different topic modeling techniques have been developed to organize the deluge of available data of...
As the market trends towards larger hard disk drives to reduce operational costs, the throughput per terabyte (TB) is concurrently decreasing. Simultaneously, the shift of data reconstruction to earlier stages of data processing pipelines—up to the experimental triggers—is transforming the usage of storage resources. These resources are now expected to support multiple read cycles, as required...
In view of the high luminosity campaign of the LHC (HL-LHC), the computational requirements of the ATLAS experiment are expected to increase remarkably in the coming years. In particular, simulation of Monte Carlo events is immensely demanding from the computational point of view and their limited availability is one of the major sources of uncertainty in many analyses. The main bottleneck in...
La Scienza Aperta si è affermata come paradigma dominante in tutti i settori della ricerca. Nella fisica nucleare e subnucleare, le grandi collaborazioni hanno fin da subito adottato i principi FAIR per la gestione dei dati, un approccio che si sta progressivamente diffondendo a comunità scientifiche più piccole e singoli esperimenti. Per favorire la concreta applicazione dei principi FAIR,...
Con la nascita dell’infrastruttura INFN Cloud, inizialmente concepita per rispondere alle necessità delle collaborazioni CYGNO e QUAX, e più recentemente attraverso il lavoro svolto nell’ambito del WP3 dello Spoke 2-PNRR, è stato sviluppato un computing model per piccoli e medi esperimenti di astroparticelle. Questo modello è progettato per soddisfare i requisiti essenziali della gestione dei...
CTLab4ET (Computing Technology Laboratory for ET) was established under the ETIC (Einstein Telescope Infrastructure Consortium) project to provide the Einstein Telescope (ET) collaboration with a dedicated environment—nicknamed “TechZoo”—for testing and benchmarking emerging computing technologies. With ET’s operational horizon extending roughly a decade into the future, it is mandatory to...
