    The snow package provides support for simple parallel computing on a
    network of workstations using R.  A master R process calls makeCluster
    to start a cluster of worker processes; the master process then uses
    functions such as clusterCall and clusterApply to execute R code on
    the worker processes and collect and return the results on the master.
    This framework supports many forms of "embarrassingly parallel"
    computations.
  
    Snow can use one of four communications mechanisms: sockets, PVM, MPI,
    or NetWorkSpaces (NWS).  NWS support was provided by Steve Weston.
    PVM clusters use the rpvm package; MPI clusters use package Rmpi; NWS
    clusters use package nws.  If pvm is used, then pvm must be started,
    either using a pvm console (e.g the pvm text console or the graphical
    xpvm console, both available with pvm) or from R using functions
    provided by rpvm.  Similarly, LAM-MPI must be started, e.g.  using
    lamboot, for MPI clusters that use Rmpi and LAM-MPI.  If NWS is used,
    the NetWorkSpaces server must be running.  SOCK clusters are the
    easiest approach for using snow on a single multi-core computer as
    they require no additional software.
