1. Geometry parallel sessions
Monday & Thursday

2. Geometry / tracking performance
Performance penalties introduced by tracking in magnetic-field
CMS setup, performance study by P.Arce
Tracking performance (field free) better than GEANT3
25% of total time penalty due to transportation in field
Need to measure achieved accuracy in Geant3 and Geant4
TODOs
To study effect of using different steppers
Repeat tests on Solaris architecture
Code review
Create dedicated system test for magnetic field with variable setup (geometry/stepper)
Development: use of safety in G4propagationInField and G4ChordFinder

3. Geometry development/requirements
GDML binding (XML, STEP)
Field performance
Extension of reflection for parameterised volumes
Implementation of divisions in Geant4
Testing on tolerances for spherical and cylindrical surfaces (G4Sphere)
