Member Function Documentation

def lsst.ctrl.pool.parallel.BatchCmdLineTask.batchCommand	(	cls,
		args
	)

inherited

Return command to run CmdLineTask.

Parameters

cls	Class
args	Parsed batch job arguments (from BatchArgumentParser)

Definition at line 476 of file parallel.py.

def lsst.ctrl.pool.parallel.BatchCmdLineTask.batchWallTime	(	cls,
		time,
		parsedCmd,
		numCores
	)

inherited

Return walltime request for batch job.

Subclasses should override if the walltime should be calculated differently (e.g., addition of some serial time).

Parameters

cls	Class
time	Requested time per iteration
parsedCmd	Results of argument parsing
numCores	Number of cores

Definition at line 461 of file parallel.py.

def lsst.ctrl.pool.parallel.BatchCmdLineTask.logOperation	(	self,
		operation,
		catch = `False`,
		trace = `True`
	)

inherited

Provide a context manager for logging an operation.

Parameters

operation	description of operation (string)
catch	Catch all exceptions?
trace	Log a traceback of caught exception?

Note that if 'catch' is True, all exceptions are swallowed, but there may be other side-effects such as undefined variables.

		args,
		kwargs
	)
