Member Function Documentation

dolfin_error()

void Logger::dolfin_error	(	std::string	location,
		std::string	task,
		std::string	reason,
		int	mpi_rank = -1
	)		const

Print error message, prefer this to the above generic error message

dump_timings_to_xml()

void Logger::dump_timings_to_xml	(	std::string	filename,
		TimingClear	clear
	)

Dump a summary of timings and tasks to XML file, optionally clearing stored timings. MPI_MAX, MPI_MIN and MPI_AVG reductions are stored. Collective on Logger::mpi_comm().

list_timings()

void Logger::list_timings	(	TimingClear	clear,
		std::set< TimingType >	type
	)

List a summary of timings and tasks, optionally clearing stored timings. MPI_AVG reduction is printed. Collective on Logger::mpi_comm().

monitor_memory_usage()

void Logger::monitor_memory_usage

(

)

Monitor memory usage. Call this function at the start of a program to continuously monitor the memory usage of the process.

timing()

std::tuple< std::size_t, double, double, double > Logger::timing	(	std::string	task,
		TimingClear	clear
	)

Return timing (count, total wall time, total user time, total system time) for given task, optionally clearing all timings for the task

timings()

Table Logger::timings	(	TimingClear	clear,
		std::set< TimingType >	type
	)

Return a summary of timings and tasks in a Table, optionally clearing stored timings
