static TimePoint start_time
Start time of program, allows you to specify the actual time of program (see format_hh_mm_ss method)
LoggerOptions()
Forbidden constructor.
#define ASSERT(expr)
Allow use shorter versions of macro names if these names is not used with external library.
bool no_log_
Turn off logger file output.
Dedicated class for storing path to input and output files.
~LoggerOptions()
Destructor.
void open_stream(Stream &stream) const
static LoggerOptions & get_instance()
Getter of singleton instance object.
int get_mpi_rank()
Returns number of actual process, if MPI is not supported returns -1.
std::ofstream file_stream_
Stream for storing logger messages to file.
bool init_
Flag sign if logger is initialized by set_log_file method.
void set_log_file(std::string log_file_base)
Initialize instance object in format 'log_file_base.process.log'.
static LoggerOptions * instance_
Singleton instance.
void reset()
Reset MPI rank and log file name.
Global macros to enhance readability and debugging, general constants.
#define WarningOut()
Macro defining 'warning' record of log.
int setup_mpi(MPI_Comm comm)
Set rank of actual process by MPI communicator.
int mpi_rank_
Actual process number.
