IBM to Drop Itanium

Hack Jandy writes "Xbitlabs is reporting that IBM chose not to persue Itanium in their next generation server lineup because of the "market acceptance issues" of the platform. They will still continue with new revisions of Xeon servers, however. With IBM's investments in Power, I can't help but think the writing was already on the wall.

      Actually, that hardly does it justice. pSeries (formerly RS/6000), yes, but also iSeries (formerly AS/400) is now POWER. The new OpenPower line of systems from IBM can run AIX, i5/OS (formerly OS/400), and Linux. In fact, it can run them simultaneously thanks to IBM's really good server partitioning technology (you can partition down to 1/10 of a CPU!).

      I'm currently doing some development work on one of these boxes (running Linux on POWER) and let me tell you, it just smokes. Runs circles around Itanium, even before you start parallelizing (which is usually the case, since you're always going to have a dual-core chip, maybe even several of them).

      IBM has absolutely no reason to continue supporting Itanium. It doesn't buy them anything. Itanic is an architecture nobody wants. If Intel hadn't sank so much R&D into it while still being able to live off the revenue from their 32-bit processors (and now, their AMD64 clones), Itanium would have been shelved a year ago.

      The compiler is the proper place for the optimisations, the processor should be left to do the actual processing.

      The theory behind the highly-touted JIT optimizations for the JVM is that it's often better to optimize at run-time, when you know the data, then at compile time when you don't. And compilers don't usually have even the minimal knowledge the programmers have about which switches will be taken.

      Intel's iAPX432 should have warned it about depending too much on the compiler. The iAPX432, the replacement for the 80286, was an intrepit chip of unique design that was sunk, in part, by a lack of compilers that could create compentent code for it. The benchmark compiler would always use the 700-cycle procedure call instead the cheaper, more specialized procedure calls available, for example.

      And what happens when the underlying chip changes? You optimize for a Pentium in very different ways than for an i386 or a Pentium III, especially in the ordering that the Itanium wanted to shove to the compiler.

Hence the market opportunity for Montecito is about 18 months so it's not worth IBM's effort to build a chipset for only that time.
