GeantV

Guilherme Amadio, A. Ananya, J. Apostolakis, M. Bandieramonte et autres

Abstract Full detector simulation was among the largest CPU consumers in all CERN experiment software stacks for the first two runs of the Large Hadron Collider. In the early 2010s, it was projected that simulation demands would scale linearly with increasing luminosity, …
