CMS Jet Energy Corrections case study

• Adelina Eleonora Lintuluoto (University of Helsinki (FI))

A walk through the CMS Jet Energy Corrections case study, showing the problem domain, the code organisation, the workflow specification, the usage of REANA, discussing lessons learnt, what worked well, what needs improvement. Followed by an open floor debate.

Using HTCondor compute backend

• Samuel Ross Meehan (CERN)

A walk through an ATLAS HTCondor analysis example, followed by identifiying what needs to be done to improve REANA <-> HTCondor bridge.

ATLAS RECAST

• Danika MacDonell (University of Victoria (CA))

A walk through the ATLAS RECAST reinterpretation example, followed by discussing differences when running computational workflows on RECAST and REANA, and a mini-hackathon to identify and address compatibility issues.

Using Python API

• REANA Team

A walk through demo example illustrating how to use Python APIs to run workflows on REANA from a Python code base or from a Jupyter notebook, followed by discussing further needs.

Container and workflow validation

• REANA Team

A walk through REANA client options for validating container images and workflow specifications, to catch possible problems early. Discussing most common issues such as using non-tagged container images, forcing certain UID and GID. Followed by a mini-hackathon improving the validation checks.

Open floor Raise any REANA-related topic of your interest! Open floor for discussion and mini-hackathons amongst REANA users and developers.
