Constructor & Destructor Documentation

◆ JobManager()

wrench::JobManager::JobManager ( std::shared_ptr< WMS > wms )

explicitprotected

Constructor.

Parameters

wms	the wms for which this manager is working

Member Function Documentation

◆ createPilotJob()

PilotJob * wrench::JobManager::createPilotJob ( )

Create a pilot job.

Returns: the pilot job

Exceptions

std::invalid_argument

◆ createStandardJob() [1/3]

StandardJob * wrench::JobManager::createStandardJob	(	std::vector< WorkflowTask * >	tasks,
		std::map< WorkflowFile *, std::shared_ptr< FileLocation > >	file_locations
	)

Create a standard job.

Parameters

tasks	a list of tasks (which must be either READY, or children of COMPLETED tasks or of tasks also included in the list)
file_locations	a map that specifies locations where files should be read/written. When unspecified, it is assumed that the ComputeService's scratch storage space will be used.

Returns: the standard job

Exceptions

std::invalid_argument

◆ createStandardJob() [2/3]

StandardJob * wrench::JobManager::createStandardJob	(	std::vector< WorkflowTask * >	tasks,
		std::map< WorkflowFile *, std::shared_ptr< FileLocation > >	file_locations,

		std::map< std::string, std::string >	service_specific_args = `{}`
	)

Submit a job to compute service.

Parameters

job	a workflow job
compute_service	a compute service
service_specific_args	arguments specific for compute services: to a BareMetalComputeService: {{"taskID", "[hostname:][num_cores]}, ...} If no value is not provided for a task, then the service will choose a host and use as many cores as possible on that host. If a "" value is provided for a task, then the service will choose a host and use as many cores as possible on that host. If a "hostname" value is provided for a task, then the service will run the task on that host, using as many of its cores as possible If a "num_cores" value is provided for a task, then the service will run that task with this many cores, but will choose the host on which to run it. If a "hostname:num_cores" value is provided for a task, then the service will run that task with the specified number of cores on that host. to a BatchComputeService: {{"-t":"<int>" (requested number of minutes)},{"-N":"<int>" (number of requested hosts)},{"-c":"<int>" (number of requested cores per host)}[,{"-u":"<string>" (username)}]} to a VirtualizedClusterComputeService: {} (jobs should not be submitted directly to the service)} to a CloudComputeService: {} (jobs should not be submitted directly to the service)}

Exceptions

std::invalid_argument
