Uh... oh.. never mind my terminology here (1st and 2nd level cache - might be wrong), but as always Wikipedia is a good starting point for understanding the problem of out-of-order execution and cache incoherency (when using multiple CPUs - but I guess depending on the architecture the cache problem could also occur on SINGLE CPU with multiple cores, each having its own NON-coherent cache): http://en.wikipedia.org/wiki/Memory_barrier Cheers, Oliver _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
