GQLink: profiling of CMS experiment¶

Settings¶

• Full detector geometry.
• Particle gun - 5 events.
• callgrind instrumentation only over G4RunManager::DoEventLoop.

Callgraphs¶

• GQLink
• Geant4

After optimizations¶

• Reusing simulator
• Field access update

Profiling over 10.03.p01 (with new GQLink improvements)¶

• Symbolic differentiation + new algorithm to evaluate polynomials
• 20 particle gun events - full detector geometry
