QuantumGraphExecutor

class lsst.ctrl.mpexec.QuantumGraphExecutor

Bases: abc.ABC

Class which abstracts QuantumGraph execution.

Any specific execution model is implemented in sub-class by overriding the execute method.

Methods Summary

execute(graph, butler)	Execute whole graph.
getReport()	Return execution report from last call to execute.

Methods Documentation

execute(graph, butler)

Execute whole graph.

Implementation of this method depends on particular execution model and it has to be provided by a subclass. Execution model determines what happens here; it can be either actual running of the task or, for example, generation of the scripts for delayed batch execution.

Parameters:

graph : QuantumGraph

Execution graph.

butler : Butler

Data butler instance

getReport() → Optional[lsst.ctrl.mpexec.reports.Report]

Return execution report from last call to execute.

Returns:

report : Report, optional

Structure describing the status of the execution of a quantum graph. None is returned if implementation does not support this feature.

Raises:

RuntimeError

Raised if this method is called before execute.
