Description

See http://geant4.web.cern.ch/geant4/UserDocumentation/UsersGuides/InstallationGuide/html/ch02s03.html (search for USolids)

For USolids, see http://aidasoft.web.cern.ch/USolids and https://gitlab.cern.ch/VecGeom/VecGeom/raw/v00-01-00/doc/GEANT4_INSTALL.md . But be sure that you set USOLIDS_VECGEOM=OFF (we don't want to use the VecGeom implementation yet - that's not ready for production).

We would like to bring this up at the stakeholders meeting to discuss the experiments' desires and intentions for incorporating vectorization in their use of Geant4.

#2 Updated by Adam Lyon over 3 years ago

Hi Kyle - So the issue here is not vectorization -- according to our resident VecGeom expert, Guilherme Lima (who is down the hall from you), VecGeom is not ready for general use. g-2 needs Geant compiled against USolids because USolids speeds up tracking through tessellated volumes by three orders of magnitude over regular Geant. The library is just better - not vectorized. -- Adam
