Simple implementation of Python multi-process communication module _python

Multi-process communication methods are many, different and several. Just try Python encapsulated a good multi-process communication module multiprocessing.connection.

Simple test out, efficiency can also, should be the socket package, the efficiency can reach 4krps, can meet the needs of a good many.

The attached code is as follows:

Client

Copy Code code as follows:

#!/usr/bin/python
#-*-Coding:utf-8-*-
"" "Download-slave
"""
__author__ = ' Zagfai '
__license__ = ' mit@2014-02 '

Import Webtul
From multiprocessing.connection import Client

A = 0
Try
While True:
A + + 1
Address = (' 10.33.41.112 ', 6666)
conn = Client (address, authkey= ' Hellokey ')
#print Conn.recv ()
D = CONN.RECV ()
Conn.close ()
Except
Pass

Print a

Server

Copy Code code as follows:

#!/usr/bin/python
#-*-Coding:utf-8-*-
"" "Downloader-master server
"""
__author__ = ' Zagfai '
__license__ = ' mit@2014-02 '

Import Webtul
From multiprocessing.connection import Listener
From threading Import Thread

Def listener ():
Address = (' 10.33.41.112 ', 6666)
Listener = Listener (address, backlog=100, authkey= ' Hellokey ')
While True:
conn = Listener.accept ()
#print ' connection accepted from ', listener.last_accepted
Try
Conn.send ({' 1 ': 2, ' 2 ': ' abc '})
Except Exception, E:
Print E
Finally
Conn.close ()
Listener.close ()

listener_th = Thread (Target=listener)
Listener_th.daemon = True
Listener_th.start ()
Listener_th.join (TIMEOUT=20)
