MultiInstanceSettings Class

Definition

Multi-instance Tasks are commonly used to support MPI Tasks. In the MPI case, if any of the subtasks fail (for example due to exiting with a non-zero exit code) the entire multi-instance Task fails. The multi-instance Task is then terminated and retried, up to its retry limit.

MultiInstanceSettings(String)

Initializes a new instance of MultiInstanceSettings.

Properties

CommonResourceFiles

A list of files that the Batch service will download before running the coordination command line. The difference between common resource files and Task resource files is that common resource files are downloaded for all subtasks including the primary, whereas Task resource files are downloaded only for the primary. Also note that these resource files are not downloaded to the Task working directory, but instead are downloaded to the Task root directory (one directory above the working directory). There is a maximum size for the list of resource files. When the max size is exceeded, the request will fail and the response error code will be RequestEntityTooLarge. If this occurs, the collection of ResourceFiles must be reduced in size. This can be achieved using .zip files, Application Packages, or Docker Containers.

CoordinationCommandLine

The command line to run on all the Compute Nodes to enable them to coordinate when the primary runs the main Task command. A typical coordination command line launches a background service and verifies that the service is ready to process inter-node messages.

NumberOfInstances

The number of Compute Nodes required by the Task. If omitted, the default is 1.

Explicit Interface Implementations

IJsonModel<MultiInstanceSettings>.Create(Utf8JsonReader, ModelReaderWriterOptions)

Reads one JSON value (including objects or arrays) from the provided reader and converts it to a model.

IJsonModel<MultiInstanceSettings>.Write(Utf8JsonWriter, ModelReaderWriterOptions)

Writes the model to the provided Utf8JsonWriter.

IPersistableModel<MultiInstanceSettings>.Create(BinaryData, ModelReaderWriterOptions)

Converts the provided BinaryData into a model.

IPersistableModel<MultiInstanceSettings>.GetFormatFromOptions(ModelReaderWriterOptions)

Gets the data interchange format (JSON, Xml, etc) that the model uses when communicating with the service.

IPersistableModel<MultiInstanceSettings>.Write(ModelReaderWriterOptions)

Writes the model into a BinaryData.
