MakeMTLogger()

Logger celeritas::MakeMTLogger ( G4RunManager const &  rm )

inline

Manually create a multithread-friendly logger.

Deprecated:

Remove in v1.0; replaced by MakeMTSelfLogger

MakeMTSelfLogger()

Logger celeritas::MakeMTSelfLogger

(

G4RunManager const &

runman

)

Manually create a G4MT-friendly logger for event-specific info.

This logger redirects Celeritas messages through Geant4. It logger writes the current thread (and maximum number of threads) in each output message, and sends each message through the thread-local G4cerr. It should be used for information about a current track or event, specific to the current thread.

In the main of your application's exectuable, set the "process-local" logger:

celeritas::self_logger() = celeritas::MakeMTSelfLogger(*run_manager);

MakeMTWorldLogger()

Logger celeritas::MakeMTWorldLogger

(

G4RunManager const &

runman

)

Manually create a logger that should only print once in MT or MPI.

A given world log message should only print once per execution: on a single process (if using MPI) and a single thread (if using MT). To provide clarity for tasking/MT Geant4 models, this will print whether it's running from a manager [M] or worker [W] thread if it's a multithreaded app.

The CELER_LOG_ALL_LOCAL environment variable allows all CELER_LOG invocations (on all worker threads) to be written for debugging.

In the main of your application's exectuable, set the "process-global" logger:

celeritas::world_logger() = celeritas::MakeMTWorldLogger(*run_manager);
