Wanna_bmw: You are wrong again. Better throw away those Intel colored glasses and look at the real world with your own eyes. IA-64 needs 64 bit OS, 64 bit utilities and 64 bit apps. Hammerdoes not need anything new. 32 bit OS, utilities and apps run just fine at full speed with no changes required. No so for IA-64. To get to stage two, support of physical memory beyond 4GB, you just need to upgrade the kernel and memory paging support utilities. In Linux, this is separate from most utilities and apps. All other software runs as is with no changes. Not so for IA-64. The third stage is recompiling/rewriting apps that need a larger than 3GB per process size (code and data) or wants the additional benefits of the larger flatter register set. Only those apps you want to either run faster or run with more memory need to be worked on. Not so for IA-64. The fourth stage occurs when everything has been moved to 64 bit mode. This could be done quickly, done slowly, or not at all. Its the customer's choice. Not so for IA-64. You have to go cold turkey straight to stage 4 unless you want to run slower than a $3 CPU (just checked Pricewatch for P-90s). Its just plain that every stage where a customer might say far enough, Hammer and x86-64 can, and Intel and IA-64 can't. People just do not throw away thousands of man years of code and years of debugging time. Just because Intel needs it, doesn't mean customers like it, want it, or are willing to pay for it, especially the latter. And where are the optimizing IA-64 compilers absolutely required for VLIW architectures? Not usable yet for decent performance in a production environment. And Linux already has a compiler for x86-64, Gnu C/C++ version 3.0.1. Linux is available for 64 bit OS, 64 bit APIs, 64 bit utilities and 64 bit apps. It is in alpha test awaiting general availability of systems for testing. Check out x86-64.org . And Gnu C/C++ is considered by many to be a production class compiler. Not so for Intel's compilers.
