Description
The existing roadmaps and computing model plans from ATLAS and CMS for the HL-LHC area are primarily focused on the centralized aspect of computing: those steps that lead up to sets of files made available to physicists for analysis. The general approaches, resources used, and software frameworks for the area of “end-user physics analysis”, which starts from those files, are much less clearly defined, understood, or prescribed.
In order to better understand these aspects, IRIS-HEP, jointly with ATLAS AMG, CMS CAT and HSF DAAA, is designing a survey to capture the computational requirements from physics analysis use cases. This contribution will show first results from the survey and discuss the broader context of the effort. Following this survey, we aim to identify a set of physics analyses and define benchmark scenarios to extrapolate the concrete computing requirements to the HL-LHC era. The described workflows will provide more clarity about the role of analysis facilities and the kinds of services they should make available. It will allow for quantitative evaluation of analysis models and be a first step towards identifying what to do about analysis use cases that do not fit into the space set out by the benchmark examples.
