Ongoing activities

• Oversee testing shifts (Gunter, ?)
• Release testing using valgrind (Gabriele)
• Perform regular profiling benchmarking of G4 development and public releases for both sequential and multithreaded mode (Soon, Krzysztof)

Developments

• Improve and enhance "testing shifts"
  • Improve documentation on tools and process in use(Gunter, shifters)
• Enhance integration testing
  • Complete integration checking for memory errors using valgrind runs into integration testing (Gunter)
  • Study possibility to generate trace-back in case of crash of a test (Gunter)
  • Evaluate how to provide physics reference files in nightly testing and implement the solution. (Gunter, Andrea, ...)
• Improve testing of multithreaded G4
  • Evaluate thread-safety checkers tools
  • Choose a tool to create a test checking for thread safety, including a check for new globals/statics (Andrea + ...)
  • Evaluate G4 performance for MT on different architectures (Andrea)
  • Measure memory consumption in MT and identify strategies for memory consumption reduction in MT (Andrea)
• In collaboration with US Advanced Scientific Computing Research (ASCR) institutions, conduct studies to measure and improve Geant4 computing performance:
  • review hadronic cross section calculation
  • finalize the review of the standard EM physics codes
  (Daniel,Soon,Krzysztof,Philippe).
• Document past and current code reviews, and list opportunities for future reviews(Krzysztof, Soon).
• Extend CPU performance measurements on different computer architectures and programing models
• benchmark Geant4/MT applications on Intel Xeon/Phi(MIC) (Soon)
• develop TBB applications on MIC (both offload and native mode) (Soon)
• Migrate nightly testing from Electric Commander to Jenkins (Gunter, ..)
• Continue to encourage the collaboration to provide more tests and more rigorous tests, e.g. tests that systematically check conservation laws (All)
