Hi Steve,
Thank's for your answer. I have done exactly the same test than you:
- Small changes in perf/remote_thr.cpp file
- Compile it and run it
- Look at tcpdump output
but on my Red Hat4 host, tcpdump is desperately silent.
I have tried on my Ubuntu 12.04 with zeromq 3.2.3 using OpenPGM 5.1.118
and 5.2.122 and obviously both cases run fine.
From what I understand from the result of your lsb_release command,
your RHE4 host is 64 bits. Mine is 32. Could it be the reason
of the problem?
Is it the way I have compiled zeromq for RHE4 (previously reported)
which results in this issue?
Here is the result of lsb_release -a on my host
LSB Version:

Thank's for your help

Modify the stock remote_thr.cpp to use a ZMQ_PUB socket then define a
rate limit slightly higher than the default,
s = zmq_socket (ctx, ZMQ_PUB);
if (!s) {
printf ("error in zmq_socket: %s\n", zmq_strerror (errno));
return -1;
}
// Add your socket options here.
// For example ZMQ_RATE, ZMQ_RECOVERY_IVL and ZMQ_MCAST_LOOP for PGM.
int rate = 10 * 1000;
rc = zmq_setsockopt (s, ZMQ_RATE, (void*)&rate, sizeof (rate));
if (rc != 0) {
printf ("error in zmq_setsockopt: %s\n", zmq_strerror (errno));
return -1;
}
Running the following,
[steve-o@nylabdev4 perf]$ *./remote_thr
