Yes, the example you have provided works. But I was trying a message size
other than 1, and it didn't work for me.
Also, I tried to wrap the functionality of py_remote_thr in a class. The
method "bind('EL','GQ')' method gives an assertion error in locator.cpp
cmd == get_ok_id
here is my python class. Everything is exactly the same as py_remote_thr.py
except its wrapped in a class
self.z = libpyzmq.Zmq(host = hostname)
self.message_size = message_size
self.message_count = message_count
self.msg = ''.join(['a' for n in range(0,self.message_size)])
x = remoteSend("localhost",10,100)
for i in range(0,x.message_count):
