Re: [Pympi-users] Idle as the console/ TCP locked down, so IDLE loopback doesn't work

[Pat M. <pat...@ll...>]

I modified Julian's IDLE startup script to put in an input
adapter

% cat pyMPI_idle.py
import mpi
import sys

if (mpi.rank == 0):
    import idlelib.PyShell
    class adapter(idlelib.PyShell.ModifiedInterpreter):
       base = idlelib.PyShell.ModifiedInterpreter
       def runsource(self,source):
          mpi.bcast_input_to_slaves(source+'\n')
          return self.base.runsource(self,source)
    idlelib.PyShell.ModifiedInterpreter = adapter

    idlelib.PyShell.main()

I added a routine to the mpi module that allows alternate
IO routines to properly broadcast input data to the waiting
slaves...  Its called (unimaginatively) mpi.bcast_input_to_slaves()

The adapter in IDLE calls it right before it executes a completed
IDLE input line.

I did a very quick test....
% mpirun -np 4 pyMPI -i pyMPI_idle.py -n

< now in the IDLE window >

 >>> 3
3
 >>> mpi.rank
0
 >>> mpi.allreduce(mpi.rank.mpi.SUM)
6
