Function Documentation

void destroyCheckpoint

(

)

Remove all memory associated with checkpoint file and path names.

long getCheckpoint

(

)

char* getCheckpointInputFile

(

)

Return the full path to the latest checkpoint file.

int removeCheckpoints

(

)

Remove the checkpoint sub-directory

int renameCheckpointFile

(

)

Rename the checkpoint sub-directory

bool runningWithCheckpoints

(

)

void setCheckpoint	(	long	value,
		char *	outputBaseDir,
		char *	versionedOutputBaseDir
	)

Setup everything for checkpoints. Find existing checkpoint directory for restarting, setup the checkpoint filenames.

Parameters:

[in]	value	Write a checkpoint file after this many iterations of lsqr.
[in]	outputBaseDir	Be sure to send the original output base directory, not the one that has version(s). This is where we'll look for an existing checkpoint directory.
[in]	versionedOutputBaseDir	Path for output base directory. This is where the checkpoint files will go.

void setCheckpointInputFile

(

char *

filename

)

Record the path and name of a previous checkpoint file.

Parameters:

[in]

filename

Full path to a previous checkpoint file.

void writeCheckpoint	(	MAP_DEPTH_MATRIX	w,
		FITSParameters	parms,
		BaseDirectory *	baseName
	)

Write OLA inversion weights, w, to a checkpoint file in a sub-directory.

Parameters:

[in]	w	MAP_DEPTH_MATRIX containing the solution weights.
[in]	parms	FITSParameters contains header parameters and values for FITS file.
[in]	baseName	BaseDirectory structure for managing output file name.
