Hi, multithreading.pool Pool has a promissing initializer argument in its constructor. However it doesn't look possible to use it to initialize each Pool's worker with some individual value (I'd wish to be wrong here)
So, how to initialize each multithreading Pool worker with the individual values? The typical use case might be a connection pool, say, of 3 workers, where each of 3 workers has its own TCP/IP port. from multiprocessing.pool import Pool def port_initializer(_port): global port port = _port def use_connection(some_packet): global _port print "sending data over port # %s" % port if __name__ == "__main__": ports=((4001,4002, 4003), ) p = Pool(3, port_initializer, ports) # oops... :-) some_data_to_send = range(20) p.map(use_connection, some_data_to_send) best regards -- Valery A.Khamenya -- http://mail.python.org/mailman/listinfo/python-list
