Detailed Description

Hit Geant4 sensitive detectors with Celeritas steps.

Construction:

• Created during SharedParams::Initialize alongside the step collector
• Is shared across threads
• Finds all logical volumes that have SDs attached
• Maps those volumes to Celeritas geometry

Because of low-level use of Geant4 allocators through the associated Geant4 objects, the hit processors must be allocated and deallocated on the same thread in which they're used, so make_local_processor is deferred until after construction and called in the LocalTransporter constructor.

Member Function Documentation

filters()

GeantSd::Filters celeritas::GeantSd::filters ( ) const

inlinefinalvirtual

Map volume names to detector IDs and exclude tracks with no deposition.

Implements celeritas::StepInterface.

make_local_processor()

GeantSd::SPProcessor celeritas::GeantSd::make_local_processor ( StreamId  sid )

inline

Create local hit processor.

Due to Geant4 multithread semantics, this must be done on the same CPU thread on which the resulting processor used. It must be done once per thread and can be done separately.

process_steps() [1/2]

void celeritas::GeantSd::process_steps ( DeviceStepState  )

finalvirtual

Process CPU-generated hit data.

Implements celeritas::StepInterface.

process_steps() [2/2]

void celeritas::GeantSd::process_steps ( HostStepState  state )

inlinefinalvirtual

Process detector tallies (CPU).

Process detector tallies (GPU).

Implements celeritas::StepInterface.

selection()

StepSelection celeritas::GeantSd::selection ( ) const

inlinefinalvirtual

Selection of data required for this interface.

Implements celeritas::StepInterface.
