Hi,
I have been trying to get libsdp.so to wrap a simple ZMQ REQ-REP socket
in python with the following commands on two separate boxes connected
via Infiniband.
All attempts thus far at pre-loading libsdp.so have not resulted in a
successful connection via SDP sockets.
Instead, the ZeroMQ messages are passed via tcp, which results in poorer
throughput on the fabric than possible with SDP.
Is there something I am doing wrong? The code and run commands are
below. The environment and libsdp.so have been tested and shown to
function via SDP using the iperf benchmark program. 192.168.11.11
corresponds to the host infiniband IPoIB address.
Thank you.
LD_PRELOAD=/usr/lib64/libsdp.so LIBSDP_CONFIG_FILE=/etc/libsdp.conf
python2.7 server.py
LD_PRELOAD=/usr/lib64/libsdp.so LIBSDP_CONFIG_FILE=/etc/libsdp.conf
python2.7 client.py
Server code:
import zmq
context = zmq.Context()
reply = context.socket(zmq.REP)
reply.bind('tcp://192.168.11.11:5001')
while True:
msg=reply.recv()
reply.send(msg)
Client Code:
import zmq
context = zmq.Context()
request = context.socket(zmq.REQ)
request.connect('tcp://192.168.11.11:5001')
while True:
request.send('hello')
z = request.recv()
