Detailed Description

A cloud-based compute service that manages a set of physical hosts and controls access to their resources by (transparently) executing jobs in VM instances.

Constructor & Destructor Documentation

CloudService()

wrench::CloudService::CloudService	(	const std::string &	hostname,

	)

Constructor.

Parameters

hostname	the hostname on which to start the service
execution_hosts	the list of the names of the hosts available for running virtual machines
scratch_space_size	the size for the scratch storage pace of the cloud service
property_list	a property list ({} means "use all defaults")
