Ratbert, I couldn't find the diagram of Itanium's firmware spec through the link you provided. Nevertheless, I think I know what you are talking about. None of the existing layers in the Itanium hardware-abstraction architecture deals with code optimization or run-time optimization. Instead, they deal with ensuring that different IA-64 processors and platforms look identical to the operating system. This is absolutely vital for making sure that the IA-64 architecture is robust enough to make a wide impact. HP's "Dynamo" layer will either be an extra layer to Itanium's hardware-abstraction architecture, or it will be incorporated in one of the existing layers. It seems like something that only HP will implement, which means other Itanium system vendors will have to obtain performance the old fashioned way: code profiling and compile-time optimization.
