Hi all, I''m currently looking at redesigning an application and changing to boost/c++11 library components. The application reads data from an input, processes the data and then send it to an output.

The C++ Middelware Writer (CMW) may be of interest. The application you mention sounds similar to the middle tier of the CMW -- http://webEbenezer.net/build_integration.html http://webEbenezer.net/misc/cmwAmbassador.hh http://webEbenezer.net/misc/cmwAmbassador.cc

The current architecture is one thread per "device" where a device is a pair of input/output ports and one processing stage. What I'd like to do is move this to either a publish/subscribe model or some form of message-based system where an input comes in and a message is then sent to the next stage of the process. All stages will happen on the same physical/virtual machine. Are there any good pub/subscribe or message-based components using the boost architecture that works on mac osx/win32.

We don't have pub/subscribe support, but the CMW is a message-based middleware. -- Brian Wood Ebenezer Enterprises - in G-d we trust. http://webEbenezer.net (651) 251-9384
