I have modified my code for the multi-threaded beta. The code transports optical photons uses a modified copy of G4OpticalPhysics source.
(I removed the data member, G4bool wasActivated, and its logic from the code. This allowed the worker threads to create the various optical processes.)
The code runs successfully in sequential mode it appears to be unstable in multi-threaded mode. That is it is unpredictable as to whether is will run to completion. When it fails I get the following diagnostic:
G4WT7 > G4VParticleChange::Initialize() Warning theListOfSecondaries is not empty G4WT7 > All objects in theListOfSecondaries are destroyed! G4WT1 > -------- EEEE ------- G4Exception-START -------- EEEE ------- *** G4Exception : TRACK003 issued by : G4ParticleChange::CheckIt momentum, energy, and/or time was illegal *** Event Must Be Aborted *** -------- EEEE -------- G4Exception-END --------- EEEE -------
At other times with the same input it runs to completion with no diagnostics.
I noticed the extended examples, LXe, which uses G4OpticalPhysics has not been converted to be multi-threaded. Are there issues with G4OpticalPhysics for multi-threading?
