Hi. I built ZeroMQ manually as prescribed above. I point it to the norm source tree path, and on the make steps it shows that it builds the norm_file. However, I still get a "protocol not supported" issue when trying to run my app. Am I missing something? Also, in the Qt Creator .pro file, how do I add the NORM library? (e.g. LIBS += -lzmq for ZeroMQ)

the article explains this ..
u build a table for all the criteria say sub1 is orange.#.yellow and sub2 is apple.custard.*

0 orange
1 yellow
2 apple
3 custard

so sub1 bitmap will be 1100 and sub2 will be 0011
and then for each message u create a bitmap

msg apple.red.green
0 1 2 3
msg1 0 0 1 0
sub1 1 1 0 0
---
0 0 0 0 ->its not 1100 so message doesnt match, also no matching fields

msg1 0 0 1 0
sub2 0 0 1 1
---
0 0 1 0 ->its not 0011 so message doesnt match, but has one matching fields

msg orange.color.yellow
0 1 2 3
msg1 1 1 0 0
sub1 1 1 0 0
---
1 1 0 0 ->its 1100 so message matches, chk for order though

Ankush notice in the pseudocode that each function returns the value of the inner function to the caller. That's what those arrows represent. We are popping a stack.

Hi,

I am using a GUI (client) with req socket in it and beaglebone (server)with rep socket. I use lazy pirate pattern in request reply format.
I am able to commnicate with one client and one server.
When I use multiple GUI(clients) to a single beaglebone(server) there are communication breakups after few hours of running.
How to handle multiple client request at the server side?

Regards
jo

Multiple clients by jojitjojit, 24 Aug 2016 13:02

Hi there,

Working on a proof of concept on reading a queue from zeromq (pub/sub) and displaying data on a browser using node,socket,jquery.

Its a monitoring application running from crontab that starts every 5 minutes and feed arbitrary data to a zeromq queue.

My problem is how to signalize the end of that "iteraction" or the start of the next one (5 minutes period)?

I am using

<script> var skt = io(); skt.on('event', (x) => $('#msg').append($('<li>').text(x.fail))); </script>

and it gives me an appending list.

My intention is only have the latest iteration. Any way to mark the last check?

regards,

Hi, I'm new to the idea of distributed systems, so please pardon if the question appears silly. In the first diagram I don't understand the existence of arrows #9 to #12. From the function pipeline, it'd appear that the processing finishes when App D is done. As per me, after #8, we have the output, which should take at most two more network hops.

I suppose this has to do something with SOA architecture, but I'll be happy if someone could explain.

Wow, this article is an absolute jewel. I am doing a performance test with ActiveMQ, and this has helped me alot so far. Thanks!

Hey, you need to build zeromq manually with ./configure —with-norm=<norm source tree path>

Quick questions:

Is ZeroMQ a transport layer protocol? (I think yes)

And using the procedure above will I be able to generate a pcap file for the ZeroMQ protocol?

I would like to know how the IO thread pool size setting in zmq_init() will affect the performance in different situations. Thank you.

Hi,

I am trying out ZeroMQ to see if it can be used for my application. However, I have problem getting it to work.

OS: Windows 10
Programming Language: C#
SDK: VS 2015 Enterprise

From what I read in order to use it in c#, I will need clrmq (which contains clr namspace for .NET) and zmq.

I gotten the "ZeroMQ.Release.zip" from "{https}://github{dot}com/zeromq/clrzmq4/releases" and within it, it contains libzmq.dll, libsodium.dll (both from i386 folder in bin) and ZeroMQ.dll (from bin).

When I try to add references (of the mentioned 3 dlls) to my testing project, I got an error stating
"A reference to libsodium.dll and libzmq.dll could not be added. Please make sure that the file is accessible, and that it is a valid assembly or COM component."

In the end, I only manage to reference ZeroMQ.dll.

Any help would be appreciated to help me start using ZeroMQ in my testing.

Thanks.

We have embedded systems that uses RS422 serial port connections.
Is it possible to use ZeroMQ via a Serial port connection?
