Using XML (or JSON) for inter-thread communication
We all know that increasing processor speed has pretty much run its course (for now) and that the way to increased system performance is via using multiple cores and threads. However, parallel programming is difficult. One of the problems is sharing state across threads and getting race conditions etc. However, systems like web services are effectively multi-process / multi-threaded and seem to scale well. Quite often web services (and systems like them) use XML or JSON to communicate between the various systems. Which makes me wonder, can you compress the 'web services' model down to the level of threads and use XML or JSON for your inter-thread communication? Can you define your interfaces using some sort of schema and use REST or similar approaches? Would this help simplify parallel programming, perhaps as one of a basket of techniques? Does anybody have any thoughts on this? Thanks, Pete Cordell Codalogic Ltd Interface XML to C++ the easy way using C++ XML data binding to convert XSD schemas to C++ classes.
