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…
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…
HEPCloud, a New Paradigm for HEP Facilities: CMS Amazon Web Services Investigation
Burt Holzman, Lothar A. T. Bauerdick, Brian Bockelman +15
Historically, high energy physics computing has been performed on large purpose-built computing systems. These began as single-site compute facilities, but have evolved into the di…
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…
Data Access for LIGO on the OSG
Derek Weitzel, Brian Bockelman, Duncan A. Brown +3
During 2015 and 2016, the Laser Interferometer Gravitational-Wave Observatory (LIGO) conducted a three-month observing campaign. These observations delivered the first direct detec…
Exploring compression techniques for ROOT IO
Zhe Zhang, Brian Bockelman
ROOT provides an flexible format used throughout the HEP community. The number of use cases - from an archival data format to end-stage analysis - has required a number of tradeoff…
