The Future of HEP Computing Considered

We are well-used to long lead times in particle physics. Detectors that are commissioned often rely on technology that was in an R&D phase decades before and now, as the CERN community, we now plan for new accelerators that will still be…

Update on CernVM-FS

Fig. 1: Map of CVMFS cache instances. The tiered cache model is one of the techniques that helps to efficiently deploy software on /cvmfs to computing sites all over the world. Anyone who has ever used experimental software on CERN's computing…

Distributed Analysis with ROOT RDataFrame

The HL-LHC is foreseen to generate roughly thirty times more data than the LHC has produced so far. Given the available future budget estimations and expected technological evolution [1], software will play a crucial role to cover the performance…

Geant4: a modern and versatile toolkit for detector simulations

Like a good, lifelong friend who is accompanying you through all phases of life, the Geant4 detector simulation toolkit is widely used in particle physics experiments from their conception to their design, during construction and data taking, for…

The FELIX Project

If you are working on one of the ATLAS, DUNE or NA62 experiments you have surely participated to meetings in which people referred to “FELIX”, as if it were a widely-known brand. You probably guessed, after some time, that they were not referring to…

Data handling and processing for the FCC-ee

Data handling and processing for the FCC-ee Introduction The integrated Future Circular Collider study will bring about giant steps forward in many technical and engineering fields. The operation at the Z-pole of the FCC-ee machine will deliver the…

Google Summer of Code brings Students to HEP Software Projects

Google Summer of Code is a programme that brings together students wanting to code for Open Source software projects and mentors who can introduce them to exciting projects and the full software development cycle. As a major supporter of Open Source…

Tips for a better virtual experience

A year ago, as the first reports of COVID-19 infections started to reach us from China, it was almost certain that none of us really foresaw the impact that the pandemic would have on our lives and on high-energy physics as a field in 2020. As…

Random Number Generators for Precision Monte Carlos

The Monte Carlo method is used primarily for calculations that are too difficult or even impossible to perform analytically, so that as our experiments and theories become more accurate, we become more dependent on the quality of our MC calculations…

CernVM 2019 Workshop

From 3rd June to 5th June, the 2019 CernVM Workshop took place. As about every 18 months, the CernVM workshop brings together software developers from EP-SFT, computing experts from the LHC experiments, WLCG system operators, and invited speakers…
