Cwrench::BandwidthMeterService | A service that measures and records bandwidth usage on a set of links at regular time intervals |
▼Cwrench::ComputeService | The compute service base class |
Cwrench::BareMetalComputeService | A compute service that manages a set of multi-core compute hosts and provides access to their resources |
Cwrench::BatchComputeService | A batch-scheduled compute service that manages a set of compute hosts and controls access to their resource via a batch queue |
▼Cwrench::CloudComputeService | 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 |
Cwrench::VirtualizedClusterComputeService | A virtualized cluster-based compute service |
Cwrench::HTCondorComputeService | A workload management framework compute service |
Cwrench::EnergyMeterService | A service that measures and records energy consumption on a set of hosts at regular time intervals |
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::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) |
