Detailed Description

An action execution service that:

• Accepts only ready actions
• Run actions FCFS w.r.t to memory constraints without backfilling
• Will oversubscribe cores in whatever way
• Attempts some load balancing
• Tries to execute actions with as many cores as possible

Constructor & Destructor Documentation

ActionExecutionService()

wrench::ActionExecutionService::ActionExecutionService	(	const std::string &	hostname,
		std::map< std::string, std::tuple< unsigned long, double >>	compute_resources,
		std::shared_ptr< Service >	parent_service,
		WRENCH_PROPERTY_COLLECTION_TYPE	property_list = {},
		WRENCH_MESSAGE_PAYLOADCOLLECTION_TYPE	messagepayload_list = {}
	)

Constructor.

Parameters

hostname	the name of the host on which the service should be started
compute_resources	a map of <num_cores, memory> tuples, indexed by hostname, which represents the compute resources available to this service. use num_cores = ComputeService::ALL_CORES to use all cores available on the host use memory_manager_service = ComputeService::ALL_RAM to use all RAM available on the host
parent_service	the parent compute service (nullptr if not known at this time)
property_list	a property list ({} means "use all defaults")
messagepayload_list	a message payload list ({} means "use all defaults")
