Member Function Documentation

batchCommand()

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

inherited

Return command to run CmdLineTask.

    @param cls: Class
    @param args: Parsed batch job arguments (from BatchArgumentParser)

Definition at line 476 of file parallel.py.

batchWallTime()

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).

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

Reimplemented in lsst.ctrl.pool.test.demoTask.DemoTask.

Definition at line 461 of file parallel.py.

logOperation()

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

inherited

Provide a context manager for logging an operation.

    @param operation: description of operation (string)
    @param catch: Catch all exceptions?
    @param 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.

Definition at line 502 of file parallel.py.

parseAndRun()

def lsst.ctrl.pool.parallel.BatchPoolTask.parseAndRun	(		cls,
		*	args,
		**	kwargs
	)

Run with a MPI process pool

Definition at line 534 of file parallel.py.

parseAndSubmit()

def lsst.ctrl.pool.parallel.BatchCmdLineTask.parseAndSubmit (   cls,   args = None, **  kwargs  )

inherited

Definition at line 435 of file parallel.py.
