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

CloudComputeService()

wrench::CloudComputeService::CloudComputeService	(	const std::string &	hostname,
		std::vector< std::string > &	execution_hosts,
