/ATLAS Collaboration
The ATLAS experiment is using large High Performance Computers (HPC's) and fine grained simulation workflows (Event Service) to produce fully simulated events in an efficient manner. ATLAS has developed a new software component (Harvester) which provides resource provisioning and workload shaping. [...]

Report from Working Group 3 : Beyond the Standard Model physics at the HL-LHC and HE-LHC
/ Cid Vidal, Xabier (Santiago de Compostela U., IGFAE) ; D'Onofrio, Monica (Liverpool U.) ; Fox, Patrick J (Fermilab) ; Torre, Riccardo (CERN ; INFN, Genoa) ; Ulmer, Keith A (Colorado U.) ; Aboubrahim, Amin (Northeastern U.) ; Albert, Andreas (RWTH Aachen U.) ; Alimena, Juliette (Ohio State U., Columbus (main)) ; Allanach, Benjamin C (Cambridge U., DAMTP) ; Alpigiani, Cristiano (Washington U., Seattle) et al.
This is the third out of five chapters of the final report [1] of the Workshop on Physics at HL-LHC, and perspectives on HE-LHC [2]. It is devoted to the study of the potential, in the search for Beyond the Standard Model (BSM) physics, of the High Luminosity (HL) phase of the LHC, defined as $3$ ab$^{-1}$ of data taken at a centre-of-mass energy of 14 TeV, and of a possible future upgrade, the High Energy (HE) LHC, defined as $15$ ab$^{-1}$ of data at a centre-of-mass energy of 27 TeV.

Fine-grained processing towards HL-LHC computing in ATLAS
/ ATLAS Collaboration
During LHC's Run-2 ATLAS has been developing and evaluating new fine-grained approaches to workflows and dataflows able to better utilize computing resources in terms of storage, processing and networks. The compute-limited physics of ATLAS has driven the collaboration to aggressively harvest opportunistic cycles from what are often transiently available resources, including HPCs, clouds, volunteer computing, and grid resources in transitional states.

Grid production with the ATLAS Event Service
/ ATLAS Collaboration
ATLAS has developed and previously presented a new computing architecture, the Event Service, that allows real time delivery of fine grained workloads which process dispatched events (or event ranges) and immediately streams outputs. The principal aim was to profit from opportunistic resources such as commercial cloud, supercomputing, and volunteer computing, and otherwise unused cycles on clusters and grids. [...]
