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…
Toward real-time data query systems in HEP
Jim Pivarski, David Lange, Thanat Jatuphattharachat
Exploratory data analysis tools must respond quickly to a user's questions, so that the answer to one question (e.g. a visualized histogram or fit) can influence the next. In some…
Optimizing ROOT IO For Analysis
Brian Bockelman, Zhe Zhang, Jim Pivarski
The ROOT I/O (RIO) subsystem is foundational to most HEP experiments - it provides a file format, a set of APIs/semantics, and a reference implementation in C++. It is often found…
CMS Analysis and Data Reduction with Apache Spark
Oliver Gutsche, Luca Canali, Illia Cremer +12
Experimental Particle Physics has been at the forefront of analyzing the world's largest datasets for decades. The HEP community was among the first to develop suitable software an…
Fast Access to Columnar, Hierarchically Nested Data via Code Transformation
Jim Pivarski, Peter Elmer, Brian Bockelman +1
Big Data query systems represent data in a columnar format for fast, selective access, and in some cases (e.g. Apache Drill), perform calculations directly on the columnar data wit…
Big Data in HEP: A comprehensive use case study
Oliver Gutsche, Matteo Cremonesi, Peter Elmer +7
Experimental Particle Physics has been at the forefront of analyzing the worlds largest datasets for decades. The HEP community was the first to develop suitable software and compu…
