Athena Software and Computing Updates - July 22, 2021

Updates on Athena Software and Computing WG meeting held on July 22, 2021. Full simulation benchmarks setup, environment variable settings, reconstruction progress, and instructions on pulling necessary codes in the containerized environment are discussed. Advice on frequent code pulls highlighted for developers. Detector options preparation also mentioned.

Presentation Transcript

1. Status of Athena SW Wednesday 2021-07-22 The Software and Computing WG Conveners: Andrea Bressan (University of Trieste and INFN) , Dmitry Romanov (Jefferson lab) , Sylvester Joosten (Argonne National Laboratory) , Whitney Armstrong (Argonne National Laboratory) , Wouter Deconinck (The University of Manitoba) 1

2. Updates Full simulation benchmarks are being setup; these benchmarks run the full chain: simulation and reconstruction Git clone https://eicweb.phy.anl.gov/EIC/benchmarks/reconstruction_benchmarks.git Cd reconstruction_benchmarks ./benchmarks/full/full_reconstruction.sh Have a look to https://eic.phy.anl.gov/ip6/index.html

3. Environment variables There are (sometimes) environment variables to be set export ATHENA_PREFIX=/home/bressan/MonteCarlo/eic/DD4/local export JUGGLER_DETECTOR=athena export DETECTOR_PATH=/opt/detector/share/athena export JUGGLER_INSTALL_PREFIX=$ATHENA_PREFIX You have also to source /opt/detector/setup.sh (we are discussing about having env variables set within this script). Reconstruction Tracking reconstruction is working again Some problems with the DIRC implementation will be solved soon For developers, frequent pull outs are needed (even more than one/per day)

4. What do you need to pull? The containerized environment curl https://eicweb.phy.anl.gov/containers/eic_container/- /raw/master/install.sh | bash Simulation codes: git clone https://eicweb.phy.anl.gov/EIC/detectors/athena.git git clone https://eicweb.phy.anl.gov/EIC/detectors/ip6.git ln -s ../ip6/ip6 athena/ip6 Reconstruction codes: git clone https://eicweb.phy.anl.gov/EIC/juggler.git (for reconstruction) git clone https://eicweb.phy.anl.gov/EIC/eicd.git (for the data model) Git clone https://eicweb.phy.anl.gov/EIC/NPDet.git (for Nuclear Physics detector library) Compiling (for most of them): cmake -B build -S . -DCMAKE_INSTALL_PREFIX=$ATHENA_PREFIX -DCMAKE_CXX_STANDARD=17

5. Preparation of detector options: B-0.0 and B-1.0 Option 0 is to go with two separated branches (not the master branch); of course one needs to find a solution to keep both branches aligned.
