Returns: the WorkflowFile instance

Exceptions

std::invalid_argument

◆ addTask()

WorkflowTask * wrench::Workflow::addTask	(	std::string	id,
		double	flops,

Create and add a new computational task to the workflow.

Parameters

id	a unique string id
flops	number of flops
min_num_cores	the minimum number of cores required to run the task
