Team Composition of the team → team: 7 EC - 9 CNRS – 17 IT (6. 4 FTE) on ITK & HGTD – 2 IT (0. 9 FTE) on grid – 1 postdoc – 7 Ph. D → analyses: Performance: large jets calibration; b-jets tagging ; ETmiss reconstruction Measurement of inclusive jet and dijet cross-sections Higgs boson: observation of Hbb; Hγγ mass measurement, couplings, cross section BSM physics : diphoton resonance; dijets resonance; SUSY particles in γγ+MET Top quark : mass Involvement of the team in computing (based on OTP pages report) was ~1 FTE in 2017, 1. 5 FTE in 2018, 1. 7 FTE in 2019 Staff IE/IR: 1 IR+1 IE GRIF-LPNHE (1. 1 FTE Class 4) Staff physicist : CAF+FR-cloud (0. 45 FTE C 3), shift computing (0. 13 FTE C 2) Involvement of the team in software (based on OTP pages report) was ~0. 9 FTE in 2016, 1. 4 FTE in 2017 and 2018, 1. 6 FTE in 2019 Staff physicist : 0. 20 FTE in C 2 (shift analysis/reco), 1. 40 FTE in C 3 (detector/ upgrade ~0. 6 FTE, analysis ~0. 8 FTE) ATLAS France CAF-PAF meeting, 28 th November 2019

Analysis and needs Detector studies (local/CERN) → pixels & HGTD studies : similar to last year Performance studies (local/CERN/CC-IN 2 P 3/GRID) → jets & b-tagging studies : similar to last year Analyses studies (local/CERN/CC-IN 2 P 3/GRID) → Higgs studies : similar to last year → Top studies : on-going move from local to CC-IN 2 P 3 batch system Analyses using Machine Learning → Neural Networks for online electron filtering use of Neural Ringer and ML to reduce CPU demand Last year studies, on GPUS on different platforms, ~1. 5 years-gpu → Optimization of detector design → MC sample reweighting ⇒ ask for 6 months-GPU use at CC-IN 2 P 3 farm ATLAS France CAF-PAF meeting, 28 th November 2019

Computing resources in 2020 « Grid » resources (correspond to Tier 2 pledged ressources) - storage = 1050 TB (+100 TB wrt 2019) - computing = 10500 HS 06 (i. e ~1050 cpu) (+10000 HS 06 wrt 2019) Other « grid » resources (correspond to non pledged ressources) - storage = 500 TB in LOCALGROUPDISK (+200 TB wrt 2019) - computing ~ 12000 HS 06 through fairshare of GRIF-LPNHE site Other local (lab, university) resources (whatever is non grid) - storage : ~100 TB attached to local server (ceph, sps-like) - computing : 1 group server with 32 cores, no batch system - cloud : ~30 TB + ~500 cores, not yet used - high performance computing (not used in practice) - at LPNHE : 1 server with 2 GPU K 2200, 1 server with 2 Xeon. Phi - at Sorbonne University : several clusters, but old OS / no singularity ATLAS France CAF-PAF meeting, 28 th November 2019

Near future Activities of the team →evolution: stable in the 2 coming years Resources and needs → Limited amount of computing ressource locally → cloud site : ready but need to learn how to use it ⇒ development rely on 1 IE who is at 50% at LPNHE, already working for GRIF-LPNHE, only limited user-support → resources of university : for HPC + GPU, but need Singularity to compile basic codes (ROOT), no improvement foreseen → needs for storage at CC-IN 2 P 3 (as reported to CAF in September) : mostly for Hbb/Top analysis, on sps : 50 TB in 2020 (+10 TB wrt 2019) 50 TB on LGD in 2020 (+10 TB wrt 2019) ATLAS France CAF-PAF meeting, 28 th November 2019
