Detailed Description

A class that implement methods to read workflow files provided by the Pegasus project.

Member Function Documentation

static Workflow* wrench::PegasusWorkflowParser::createExecutableWorkflowFromJSON	(	const std::string &	filename,
		const std::string &	reference_flop_rate,
		bool	redundant_dependencies = `false`
	)

static

Create an NON-abstract workflow based on a JSON file.

Parameters

filename	the path to the JSON file
reference_flop_rate	a reference compute speed (in flops/sec), assuming a task's computation is purely flops. This is needed because JSON files specify task execution times in seconds, but the WRENCH simulation needs some notion of "amount of computation" to apply reasonable scaling. (Because the XML platform description specifies host compute speeds in flops/sec). The times in the JSON file are thus assumed to be obtained on an machine with flop rate reference_flop_rate.
redundant_dependencies	Workflows provided by Pegasus sometimes include control/data dependencies between tasks that are already induced by other control/data dependencies (i.e., they correspond to transitive closures or existing edges in the workflow graphs). Passing redundant_dependencies=true force these "redundant" dependencies to be added as edges in the workflow. Passing redundant_dependencies=false will ignore these "redundant" dependencies. Most users woudl likely pass "false".

Exceptions

std::invalid_argument

static Workflow* wrench::PegasusWorkflowParser::createWorkflowFromDAX	(	const std::string &	filename,
		const std::string &	reference_flop_rate,
		bool	redundant_dependencies = `false`
	)

static

Create an abstract workflow based on a DAX file.

Parameters

filename	the path to the DAX file
reference_flop_rate	a reference compute speed (in flops/sec), assuming a task's computation is purely flops. This is needed because DAX files specify task execution times in seconds, but the WRENCH simulation needs some notion of "amount of computation" to apply reasonable scaling. (Because the XML platform description specifies host compute speeds in flops/sec). The times in the DAX file are thus assumed to be obtained on an machine with flop rate reference_flop_rate.
redundant_dependencies	Workflows provided by Pegasus sometimes include control/data dependencies between tasks that are already induced by other control/data dependencies (i.e., they correspond to transitive closures or existing edges in the workflow graphs). Passing redundant_dependencies=true force these "redundant" dependencies to be added as edges in the workflow. Passing redundant_dependencies=false will ignore these "redundant" dependencies. Most users would likely pass "false".
