Detailed Description

template<MemSpace M>
class celeritas::optical::CoreState< M >

Store all state data for a single thread.

When the state lives on the device, we maintain a separate copy of the device "ref" in device memory: otherwise we'd have to copy the entire state in launch arguments and access it through constant memory.

Todo:

Encapsulate all the action management accessors in a helper class.

Member Function Documentation

insert_primaries()

template<MemSpace M>

void celeritas::optical::CoreState< M >::insert_primaries ( Span< TrackInitializer const >  host_primaries )

finalvirtual

Inject primaries to be turned into TrackInitializers.

These will be converted by the ProcessPrimaries action.

Implements celeritas::optical::CoreStateInterface.

warming_up()

template<MemSpace M>

bool celeritas::optical::CoreState< M >::warming_up

Whether the state is being transported with no active particles.

The warmup stage is useful for profiling and debugging since the first step iteration can do the following:

• Initialize asynchronous memory pools
• Interrogate kernel functions for properties to be output later
• Allocate "lazy" auxiliary data (e.g. action diagnostics)
