Detailed Description

template<class T>
class celeritas::TrackExecutor< T >

Call a CoreTrackView executor for a given ThreadId.

This class can be used to call a functor that applies to CoreTrackView using a ThreadId, so that the tracks can be easily looped over as a group on CPU or GPU. It applies a remapping from thread to slot if the tracks are sorted. Otherwise, thread and track slot have the same numerical value.

This is primarily used by ActionLauncher .

void foo_kernel(CoreParamsPtr const params,
                CoreStatePtr const state)
{
    TrackExecutor execute{params, state, MyTrackApplier{}};
 
    for (auto tid : range(ThreadID{123}))
    {
        step(tid);
    }
}

Todo:

Rename to ThreadExecutor. The template parameter, which must operate on a core track view, is a track executor.
