Detailed Description

Print diagnostic output about what's in what slots.

Currently this only prints the particle ID as a function of track slot, which can later be combined with postprocessing data to print the charge of each particle. We could in the future extend the class to use thread ID and/or write action ID or any other ID/status instead. Special IDs are:

• -1 : track slot is inactive
• -2 : track has been flagged as an error

A "JSON lines" file (one line per step) is opened for each stream, and a separate file is opened once during construction to write appropriate metadata.

The filename base is appended with the stream ID or metadata. If the filename is a directory, that directory must already exist. For example, you could pass a filename base of slot-diag- to get filenames slot-diag-metadata.json, slot-diag-0.jsonl, etc.

Todo:

Instead of writing separate files, we should probably use a multi-stream output manager (not yet implemented) to save the result for the end.

Note

To plot the resulting files, see scripts/user/plot-slot-diagnostic.py

Constructor & Destructor Documentation

SlotDiagnostic()

celeritas::SlotDiagnostic::SlotDiagnostic	(	ActionId	action_id,
		AuxId	aux_id,
		std::string	filename_base,
		size_type	num_streams,
		std::shared_ptr< ParticleParams const >	particle
	)

Construct with IDs and filename base.

This also writes to the "metadata" JSON suffix.

Member Function Documentation

step()

void celeritas::SlotDiagnostic::step ( CoreParams const &  params, CoreStateHost &  state  ) const

final

Execute with with the last action's ID and the state.

This must be called after both create_state and begin_run .
