GQLink - Plots and Preliminary Results¶

GQLink vs. Geant4 comparison plots - with crossing planes¶

General settings¶

• stepMax: 20 mm
• deltaIntersection: 1e-5 mm
• deltaChord: 0.25 mm (not relevant for GQLink)
• deltaOneStep: 0.01 mm (overriden by epsilon)
• trackMaxLen: 1 km

epsilon = 1e-6¶

epsilon = 1e-7¶

epsilon = 1e-8¶

Comparison with QSS Solver¶

Geant4 - General settings¶

• stepMax: 20 mm
• deltaIntersection: 1e-5 mm
• deltaChord: 0.25 mm (not relevant for GQLink)
• deltaOneStep: 0.01 mm (overriden by epsilon)
• trackMaxLen: 100 m

Using QSS polynomials¶

• Important: this plots belong to the very first working implementation of QSS polynomials to find boundary crossings within Geant4. As such, it is still in need of improvements.

Geant4 - General settings¶

• stepMax: 20 mm
• deltaIntersection: 1e-5 mm
• deltaChord: 0.25 mm (not relevant for GQLink)
• deltaOneStep: 0.01 mm (overriden by epsilon)
• trackMaxLen: 100 m

epsilon = 1e-5¶

epsilon = 1e-6¶

epsilon = 1e-7¶

GQLink_Poly callgraphs¶

• GQLink_Poly callgraph - 2 planes - Raw profiler output

Using QSS polynomials - with improvements¶

Geant4 - General settings¶

• stepMax: 20 mm
• deltaIntersection: 1e-5 mm (not relevant for GQLink + QSS polynomials)
