Intel Corporation and NEC Corporation today have agreed to jointly develop High Performance Computing (HPC) system technologies that will push the boundaries of supercomputing performance. NEC will bring these technologies to market in future supercomputers based on the Intel Xeon processor. NEC’s expertise in this field coupled with the Intel Xeon processor’s outstanding performance and its accelerating vector capabilities such as AVX will allow for higher performance supercomputers, satisfying customer demand for Intel architecture based products.

Intel moving away from Itanium with NEC's help? This seems like an odd arrangement, to say the least. I thought AVX was already complete or close to complete.

AFAIK, Nehalem-EX is pretty much the death-knell for Itanium.

Nehalem-EX is only up to 8-way. Itanium really doesn't have a limit (processors numbering in the thousands not unheard of). Intel might be partnering up with NEC to move Xeon to the next level seeing as IBM and other super computer manufacturers wouldn't want anything to do with that.

Itanium was, after all, pretty much a failure (it sold way under Intel's expectations). I wouldn't be surprised if Intel is killing Itanium, exiting from the super computer market, and will only offer Nehalem-EX. It is still mysterious to me why NEC is involved though.

I semi-coherently remember those days. Intel had this huge 5+ year plan to introduce IA-64 from the top down. I, being on the bottom (desktop), wasn't too happy. Started to question my faith... why have they forsaken me? But then! A light! AMD came riding in, darkness clearing in their wake, eyes dead set on Intel. The giant asks, what could you possible do to us?! You are small, weak, and hold a laughable market share! With a sly grin AMD responds, we bring 64bit to the masses! And to deal a second blow... "it also runs your current software". With that they knew they were beat. Logic and planning were no match for heart and spirit... along with the sound of untold numbers of wallets opening.

x86-64 is vastly inferior to IA-64. IA-64 could handle 6 threads per core simultaneously in addition to processing two 32-bit instructions at once instead of a single 64-bit instruction. By releasing x86-64, AMD cemented the old, slow, tired architecture for another decade. AMD did us no favors and that hurdle will have to be still have to be crossed some day because of the severe limitations of the x86 instruction set.

Intel implemented their own version of x86-64 once AMD closed the door for a future instruction set in the near future. We're stuck with it until 128-bit quads, most likely, and I hope AMD doesn't extend x86 when that time comes or we'll all continue to be stuck with inefficient processors for modern workloads.

IA-64 was and is notoriously difficult (Along with other VLIW architectures) to write good compilers (That is, those that will be able to actually take advantage of the VLIW execution flow to speed up calculations) for. It isn't the end solution, either.

Oh, no dispute in that regard. It was certainly a screw you move, and well, we know how much the masses love a screw you move.

Indeed, but at least it would have broke the stranglehold x86 has on consumer computing. That will have to happen eventually.
