Abstract

Cyber infrastructure will be a critical consideration in the development of
next generation gravitational-wave detectors. The demand for data analysis
computing in the 3G era will be driven by the high number of detections as well
as the expanded search parameter space for compact astrophysical objects and
the subsequent parameter estimation follow-up required to extract the nature of
the sources. Additionally, there will be an increased need to develop
appropriate and scalable computing cyberinfrastructure, including data access
and transfer protocols, and storage and management of software tools, that have
sustainable development, support, and management processes. This report
identifies the major challenges and opportunities facing 3G gravitational-wave
observatories and presents recommendations for addressing them.
This report is the fourth in a six part series of reports by the GWIC 3G

Edge of the Universe, ii) The Next Generation Global Gravitational Wave
Observatory: The Science Book, iii) 3G R&D: R&D for the Next Generation of
Ground-based Gravitational Wave Detectors, iv) Gravitational Wave Data
