Cwrench::FileRegistryService	A file registry service (a.k.a. replica catalog) that holds a database of which files are available at which storage services. Specifically, the database holds a set of <file, storage service> entries. A WMS can add, lookup, and remove entries at will from this database
Cwrench::JobManager	A helper daemon (co-located with and explicitly started by a WMS), which is used to handle all job executions
Cwrench::NetworkProximityService	A network proximity service that continuously estimates inter-host latencies and can be queried for such estimates
►Cwrench::StorageService	The storage service base class
Cwrench::SimpleStorageService	A storage service that provides direct access to some storage resources (e.g., one or more disks). An important (configurable) property of the storage service is SimpleStorageServiceProperty::BUFFER_SIZE (see documentation thereof), which defines the buffer size that the storage service uses. Specifically, when the storage service receives/sends data from/to the network, it does so in a loop over data "chunks", with pipelined network and disk I/O operations. The smaller the buffer size the more "fluid" the model, but the more time-consuming the simulation. A large buffer size, however, may lead to less realistic simulations. At the extreme, an infinite buffer size would correspond to fully sequential executions (first a network receive/send, and then a disk write/read). Setting the buffer size to "0" corresponds to a fully fluid model in which individual data chunk operations are not simulated, thus achieving both accuracy (unless one specifically wishes to study the effects of buffering) and quick simulation times. For now, setting the buffer size to "0" is not implemented. The default buffer size is 10 MiB (note that the user can always declare a disk with arbitrary bandwidth in the platform description XML)
