a communicator number.
a logical. If TRUE, all R objects on master are transmitted to slaves.
a buffer unit number.
mpi.bcast.Robj is an extension of
moving a general R object around from a sender to everyone.
mpi.bcast.Robj2slave does an R object transmission from
master to all slaves unless all=TRUE in which case, all master's objects with
the global enviroment are transmitted to all slavers.
mpi.bcast.data2slave transfers data (a double vector or a matrix)
natively without (un)serilization. It should be used with a huge vector or matrix.
It results less memory usage and faster transmission. Notice that data with
missing values (NA) are allowed.
mpi.bcast.Robj returns no value for the sender and the
transmitted one for others.
mpi.bcast.Robj2slave returns no value for the master
and the transmitted R object along its name on slaves.
transmits all master's functions to slaves and returns no value.
