Description

“End-user physics analysis”, starting from centrally provided files and ending with a publication, is done in many different ways. This workshop aims to address the following two questions:

What are the computational needs of representative end-user physics analyses today, in terms of overall workflow, services used, number of events and total volume of data to process, and computational cost per event?
Which scenarios should we consider to extrapolate these physics analyses’ needs toward the HL-LHC?

It follows a survey distributed to ATLAS and CMS which gathers input for discussing these questions. This IRIS-HEP "blueprint" workshop aims to produce a document summarizing a set of benchmark analyses, alongside an extrapolation of how we expect them to evolve towards the HL-LHC. The event is jointly organized with the CMS CAT group, the ATLAS AMG group, and the HSF DAWG group.

This is a hybrid event: join us at CERN or on Zoom. Please register if you are interested in attending!
