HL-LHC Analysis With ROOT
Axel Naumann, Philippe Canal, Enric Tejedor +14
ROOT is high energy physics' software for storing and mining data in a statistically sound way, to publish results with scientific graphics. It is evolving since 25 years, now prov…
ROOT for the HL-LHC: data format
Axel Naumann, Philippe Canal, Enric Tejedor +14
This document discusses the state, roadmap, and risks of the foundational components of ROOT with respect to the experiments at the HL-LHC (Run 4 and beyond). As foundational compo…
RNTuple performance: Status and Outlook
Javier Lopez-Gomez, Jakob Blomer
Upcoming HEP experiments, e.g. at the HL-LHC, are expected to increase the volume of generated data by at least one order of magnitude. In order to retain the ability to analyze th…
Exploring Object Stores for High-Energy Physics Data Storage
Javier López-Gómez, Jakob Blomer
Over the last two decades, ROOT TTree has been used for storing over one exabyte of High-Energy Physics (HEP) events. The TTree columnar on-disk layout has been proved to be ideal…
LLAMA: The Low-Level Abstraction For Memory Access
Bernhard Manfred Gruber, Guilherme Amadio, Jakob Blomer +3
The performance gap between CPU and memory widens continuously. Choosing the best memory layout for each hardware architecture is increasingly important as more and more programs b…
Software Challenges For HL-LHC Data Analysis
ROOT Team, Kim Albertsson Brann, Guilherme Amadio +21
The high energy physics community is discussing where investment is needed to prepare software for the HL-LHC and its unprecedented challenges. The ROOT project is one of the centr…
Evolution of the ROOT Tree I/O
Jakob Blomer, Philippe Canal, Axel Naumann +1
The ROOT TTree data format encodes hundreds of petabytes of High Energy and Nuclear Physics events. Its columnar layout drives rapid analyses, as only those parts ("branches") that…
A Roadmap for HEP Software and Computing R&D for the 2020s
Johannes Albrecht, Antonio Augusto Alves, Guilherme Amadio +307
Particle physics has an ambitious and broad experimental programme for the coming decades. This programme requires large investments in detector hardware, either to build new facil…
Status Report of the DPHEP Collaboration: A Global Effort for Sustainable Data Preservation in High Energy Physics
DPHEP Collaboration, Silvia Amerio, Roberto Barbera +31
Data from High Energy Physics (HEP) experiments are collected with significant financial and human effort and are mostly unique. An inter-experimental study group on HEP data prese…
The Need for a Versioned Data Analysis Software Environment
Jakob Blomer, Dario Berzano, Predrag Buncic +4
Scientific results in high-energy physics and in many other fields often rely on complex software stacks. In order to support reproducibility and scrutiny of the results, it is goo…
CernVM Online and Cloud Gateway: a uniform interface for CernVM contextualization and deployment
G. Lestaris, I. Charalampidis, D. Berzano +4
In a virtualized environment, contextualization is the process of configuring a VM instance for the needs of various deployment use cases. Contextualization in CernVM can be done b…
PROOF as a Service on the Cloud: a Virtual Analysis Facility based on the CernVM ecosystem
Dario Berzano, Jakob Blomer, Predrag Buncic +4
PROOF, the Parallel ROOT Facility, is a ROOT-based framework which enables interactive parallelism for event-based tasks on a cluster of computing nodes. Although PROOF can be used…
Micro-CernVM: Slashing the Cost of Building and Deploying Virtual Machines
J. Blomer, D. Berzano, P. Buncic +5
The traditional virtual machine building and and deployment process is centered around the virtual machine hard disk image. The packages comprising the VM operating system are care…
