Function Documentation

◆ log_level_from_env()

LogLevel celeritas::log_level_from_env ( std::string const & level_env )

Get the log level from an environment variable.

Default to Logger::default_level, which is 'info'.

◆ make_default_self_logger()

Logger celeritas::make_default_self_logger ( )

Create a default logger using the local communicator.

If MPI is enabled, this will prepend the local process index to the message.

◆ make_default_world_logger()

Logger celeritas::make_default_world_logger ( )

Create a default logger using the world communicator.

The result prints only on one processor in the world communicator group. This function can be useful when resetting a test harness.

◆ self_logger()

Logger & celeritas::self_logger ( )

Serial logger: print on every process that calls it.

Setting the "CELER_LOG_LOCAL" environment variable to "debug", "info", "error", etc. will change the default log level.

◆ world_logger()

Logger & celeritas::world_logger ( )

Parallel-enabled logger: print only on "main" process.
