Frequently Asked Questions about User Support Policy


1.If I need to discuss technical matters specific to my simulation application or ask for first-aid help, who can I contact?

Every institute and experiment participating in Geant4 has a G4 Technical Steering Board (TSB) representative who may be contacted for help with problems relating to simulations. Please contact the TSB representative closest to your project or to your laboratory. To find out who your TSB representative is go to http://cern.ch/geant4/organisation/technical_board.html. You may also post your question in the Geant4 HyperNews Forum, http://geant4-hn.slac.stanford.edu:5090/Geant4-HyperNews/index.


2.If I find a bug or other problem with the code, who should be informed?

A WWW interface, available at http://cern.ch/geant4/problemreport/, will forward the bug report to the person responsible for the affected Geant4 domain. The Geant4 web makes available a database of open incident reports, tagging the ones already fixed and showing their status. An acknowledgement of the bug report will be sent.


3.If I propose a fix, who is responsible for approving it?

The responsible person is the working group coordinator of the domain in which the fix is to be applied. This person is usually also a TSB member. If the fix affects more than one domain, the matter will be addressed by the TSB.


4.To whom should I send a proposal for an improvement in Geant4 functionality?

Any new requirement should be submitted via the automatic web system. It will be discussed at the Geant4 TSB. You may also ask your TSB representative to forward your requirement to the TSB. A new requirement will trigger a cycle of analysis, design, implementation, testing and documentation, which may involve different working groups. Any new software or enhancement which will become a part of Geant4 must be agreed upon by the TSB, which is charged with ensuring the consistency of the entire toolkit.


5.Is there a regular user meeting which I should attend?

There is only one Geant4 workshop per year. However, many experiments and institutes in the Geant4 collaboration organize their own regular and/or special Geant4 user workshops.


6.Where can I find solutions to particular problems as well as general user support?

Solutions and tips for solving practical problems can be found on an additional FAQ page. General and specific user support information is available at http://cern.ch/geant4/support.
