executeScript: Remote execution of R script in an R interface new_interface.

In Azure/AzureDSVM: Create and Manage Azure Data Science Virtual Machine(s) for Convenient Execution of Scalable and Elastic Analytics.

Description

Remote execution of R script in an R interface new_interface.

Usage

executeScript(context, resource.group, hostname, remote, username, script,
  master = "", slaves = "", compute.context = ifelse(master == "" &&
  slaves == "", "localParallel", "clusterParallel"))

Arguments

context	Authentication context of AzureSMR encapsulating the TID, CID, and key obtained from Azure Actrive Directory.
resource.group	The Azure resource group where the DSVM is created.
hostname	Name of the DSVM. Lowercase characters or numbers only. Special characters are not permitted.
remote	IP address or FQDN for a computation engine. For DSVM, it is either the fully qualified domain name (usually in the format of <hostname>.<location>.cloudapp.azure.com) or its public IP address. Note if more than one machines are used for execution, the remote is used as master node by default.
username	User name of the DSVM. It should be different from 'name'.
script	R script to be executed on remote resource(s).
master	IP address or URL of a DSVM which will be used as the master. By default is remote.
slaves	IP addresses or URLs of slave DSVMs.
compute.context	Computation context of Microsoft R Server under which the mechanisms of parallelization (e.g., local parallel, cluster based parallel, etc.) is specified. Accepted computing context include "localSequential", "localParallel", and "clusterParallel".

Details

For a "localSequential" compute context, there is no parallelism and the analytics run in a sequential manner. In the "localParallel" compute context, the analytics will be run across available cores of a computing node. The number of available cores can be checked with Microsoft RevoScaleR function rxGetOption. The "clusterParallel" compute context enables parallel computation across coputing nodes of a cluster.

Value

Status of scription execution.
