rxRemoteGetId: Provides a unique identifier for the process.

  • Article

Description

Provides a unique identifier for the process in the range [1:N] where N is the number of processes.

Usage

  rxRemoteGetId()

Details

This function is intended for use in calls to rxExec to identify the process performing a given computation.

You can also use rxRemoteGetId to obtain separate random number seeds. See the examples.

Value

In a distributed compute context, this returns the parametric ID for each node or core that executes the function. If the compute context is local, this always returns -1.

Examples


 ## Not run:

rxExec(rxRemoteGetId)

# set a seed on each node before generating random numbers
myNorm <- function(x)
{
   set.seed(rxRemoteGetId())
   rnorm(x)
}
rxExec(myNorm, ARGS=as.list(1:5))
## End(Not run)
