Set up

Requirements:

1. Access to /cvmfs

2. Access to /eos

3. To have read access to the FCC pre-generated samples, one needs to be subscribed to the following e-group (with owner approval): fcc-eos-access.

Workflow

coffea-fcc-analyses uses coffea 2024.5.0 with python 3.11 and dask in an almalinux 8 singularity container.

1. Clone the coffea-ffc-analyses repository

2. cd coffea-fcc-analyses

3. The container shell could be started with executing ./shell at the root of the coffea-ffc-analyses repository.

Once can also modify shell by editing it. The current contents of shell are :

#!/usr/bin/env bash

if [ "$1" == "" ]; then
	export COFFEA_IMAGE=coffeateam/coffea-dask-almalinux8:2024.5.0-py3.11
else
	export COFFEA_IMAGE=$1
fi

echo "Coffea Image: ${COFFEA_IMAGE}"

EXTERNAL_BIND=${PWD}

singularity exec -B /etc/condor -B /eos -B /afs -B /cvmfs --pwd ${PWD} \
	/cvmfs/unpacked.cern.ch/registry.hub.docker.com/${COFFEA_IMAGE} \
	/bin/bash --rcfile /srv/.bashrc
