◆ Output() [1/2]

SST::Output::Output	(	const std::string &	prefix,
		uint32_t	verbose_level,
		uint32_t	verbose_mask,
		output_location_t	location,
		const std::string &	localoutputfilename = `""`
	)

Constructor.

Set up output configuration.

Parameters

prefix	Prefix to be prepended to all strings emitted by calls to debug(), verbose(), fatal() and possibly output(). NOTE: No space will be inserted between the prepended prefix string and the normal output string. Prefix can contain the following escape codes: @f Name of the file in which output call was made. @l Line number in the file in which output call was made. @p Name of the function from which output call was made. @r MPI rank of the calling process. Will be empty if MPI_COMM_WORLD size is 1. @R MPI rank of the calling process. Will be 0 if MPI_COMM_WORLD size is 1. @i Thread Id of the calling process. Will be empty if number of threads is 1. @I Thread Id of the calling process. Will be 0 if number of threads is 1. @x Rank information of the calling process. Will be empty if number of MPI ranks and number of threads are both 1 Same as [@r:@i] @X Rank information of the calling process. Will be [0.0] if number of MPI ranks and number of threads are both 1 Same as [@R:@I] @t Simulation time. Will be the raw simulation cycle time retrieved from the SST Core.
verbose_level	Debugging output level. Calls to debug(), verbose() and fatal() are only output if their output_level parameter is less than or equal to the verbose_level currently set for the object
verbose_mask	Bitmask of allowed message types for debug(), verbose() and fatal(). The Output object will only output the message if the set bits of the output_bits parameter are set in the verbose_mask of the object. It uses this logic: if (~verbose_mask & output_bits == 0) then output is enabled.
location	Output location. Output will be directed to STDOUT, STDERR, FILE, or NONE. If FILE output is selected, the output will be directed to the file defined by the –debug runtime parameter, or to the file 'sst_output' if the –debug parameter is not defined. If the size of MPI_COMM_WORLD is > 1, then the rank process will be appended to the file name.
localoutputfilename.	Send the output of this class to the file identified in localoutputfilename instead of the of the normal output file set by the run time parameter –debug-file. location parameter must be set to FILE. This parameter is intended for special case debug purposes only.
