Here is the call graph for this function:

make_directory()

void lbann::file::make_directory

(

const std::string &

path

)

Create directory if needed.

std::string &

str

)

Here is the caller graph for this function:

trainer_master_make_directory()

void lbann::file::trainer_master_make_directory	(	const std::string &	path,
		lbann_comm *	comm
	)

Trainer master creates directory if needed.

Coordinate efforts to allow the trainer master to make a directory if needed and synchronizes all other trainer ranks to ensure they see a consistent state of the file system.
