Hi Zmq dev,
I am a new user for zmq and want to make use of the zmq 2.X in my C#
project.
I found that there is not c# wrapping for zmq 2.x. Is there any C#
wrapping for 2.x just like that in 1.x?
Please let me know! Thanks!
Regards,
Alex

Hi,
REQ/REP sockets have a load balancing feature. If you have 1 master
with a REQ socket that binds:
ctx = zmq.Context()
s = ctx.socket(zmq.REQ)
s.bind('tcp://127.0.0.1:')
And multiple workers that connect REP sockets to the REQ:
# Each worker does

I am not sure how to tell that from dtrace. But I can send the output
if you want.
Yes, please. The worse that can happen is that I won't
Hi Michael,
You mentioned earlier that there was a number of fixes to zero-copy
committed after 0MQ 2.0b2. Would you like me to re-run the Infiniband SDP
tests with 0MQ 2.0.6? If so, would it be helpful if I did anything
differently?
I don't think anything changed performance-wise,

No, the C# binding wasn't yet ported to 0MQ/2.0. However, it's a couple
of hours' work. Would
Thanks Martin,
Of coz I would like to tried it.
But I know nth about c++ so tried to use SWIG to generate the C#
interface last night and failed last night.
Could you send me the binding for 1.0 so that I can port it to 2.0?
Kindly Regards,
Alex

Here's the code for C# binding in 0MQ/1.0:
Hi,
Ok. Fair enough. I believe more people are struggling with the same
problem. What about writing a simple sync API implementation?
for my use case, it would be sufficient to check if the underlying queue
is empty. This should be very easy to implement by simply checking if

Hi,
The problem is that each end of the queue lives in a different thread.
Writer thread cannot access read end of the queue and vice versa.
This should not be a problem, I guess. The calling thread can see the
current write position, so the positions differ after a write.
Changes in the
Martin,
I have thought about implementing something like this in the Python
bindings using Python's builtin socket library, but having it in 0MQ
itself would be nice. Having a pure Python version would enable
people to use 0MQ in situations where they can't or don't want to
install libzmq.

Matthew,
The settings on your computer look OK.
Your test program doesn't induce the problem on my box.
Can you run it under debugger and step through zmq::resolve_ip_hostname
function to see what's happening?
Thanks.

I may be missing something obvious since I more of a lurker on this list then a
user, but the 'subscribing' line below states that it is subscribing on port
not 5551 which the original post did when 'localhost' was used.

Hi,
I made some C# bindings a few weeks ago, but just committed it and
pushed it: http://github.com/s450r1/zeromq2/blob/master/bindings/clr/Zmq.cs
However, it's only been tested to work with the 0MQ from a few weeks
ago, before the language bindings were kicked out of the core 0MQ
repository :-)
Hi,
I've been wanting to use 0MQ at work, but can't quite get the behavior
I want. I think I want P2P type connections, but run into the lack of
auto-connect code[1].
What I'm trying to get is for an application to send lots of messages
and have those stored on a queue until a client connects
Martin,
The whole XREQ/XREP business is still messy. If you absolutely need it at
the moment you can use XREQ to connect and load-balance messages to mutliple
REPs. That way you'll get what you need without a need to do any special
processing on the REP side.
I have tried the XREQ - multiple
I traced the application to the point where it calls getaddrinfo which is
failing on my linux machine. It's returning 1, with the error:

I boiled down everything to: (copied straight from ip.cpp)
