remoteCalc: Return a Distributed Vector to the Master Process

Description

remoteCalc applies a function to either one or two input objects on the slave processes. Input objects can be obtained environments, lists, and ReferenceClass objects as well as the global environment on the slave processes. The output object can be assigned into a environment or a ReferenceClass objects as well as the global environment on the slave processes.

Usage

remoteCalc(input1Name, input2Name = NULL, FUN, outputName, input1Pos = '.GlobalEnv',
input2Pos = '.GlobalEnv', outputPos = '.GlobalEnv')

Details

FUN is found by a call to match.fun and typically is either a function or a symbol (e.g., a backquoted name) or a character string specifying a function to be searched for from the environment of the call to remoteCalc.

Examples

bigGP.init(3)
mpi.bcast.cmd(x <- 0:mpi.comm.rank())
remoteCalc('x', FUN = exp, outputName = 'exp.x')
remoteLs()
pull('exp.x')
remoteCalc('x', 'exp.x', FUN = `+`, outputName = 'silly')
pull('silly')
