mpi.comm.set.errhandler: MPI_Comm_set_errhandler API
Description
mpi.comm.set.errhandler sets a communicator to MPI_ERRORS_RETURN 
instead of  
MPI_ERRORS_ARE_FATAL (default) which crashes R on any type of MPI errors.  
Almost all MPI API calls return errcodes which can map to specific MPI error 
messages. All MPI related error messages come from predefined 
MPI_Error_string.
Usage
mpi.comm.set.errhandler(comm = 1)
Value
1 if success. Otherwise 0.
Arguments
  
- comm
- a communicator number
