IBM Opens Up POWER Architecture For Licensing 131

Posted by Unknown Lamer from the finally-gonna-get-that-sweet-workstation dept.
New submitter HAL11000 was the first of many to write with news that IBM and others have formed a new consortium to license the POWER architecture to third parties "IBM puts up POWER architecture for licensing and announces the OpenPower Consortium with Google, Nvidia, Mellanox, and Tyan." Quoting El Reg: "The plan, according to McCredie, is to open up the intellectual property for the Power architecture and to allow customizations by licensees, just like ARM Holdings has done brilliantly with its ARM processors ... Nvidia is very excited about the prospects of marrying Power processors and Nvidia GPUs for both HPC and general purpose systems. ... Tyan will presumably be working on alternative motherboards to the ones that IBM has manufactured for its own use." There are mentions of the POWER firmware being "open sourced," but it is unclear if that actually means Open Source or something more like the Open Group's definition of open (vendors only).

        PowerPC cores are incredibly more ubiquitous than you probably believe. They show up all over the place. Hell, Motorola Cellphones had old tired PPC cores in them for some time, since as a contributor Moto had a license to make embedded PPC chips. And of course, it's well-known that there's a tri-core PPC in the Xbox 360. There's also a castrated little PPC core in the front of the PS3's processor, where there was a MIPS core in the PS2's. And there's a ton of little MIPS-based portable computers out there, but in recent times their sales have been cannibalized by ARM. There's no reason to believe that there couldn't be a ton of little PPC-based portables out there, if PPC were licensed like ARM. Now, allegedly, it will be. Probably too little too late, though.

        • I believe many automotive onboard computers are PPC based also.

          • And spacecraft because there are rad-hard parts available.

            The thing I wonder about is all the years of ARM driving for low power (Intel has done this too) while IBM Power (uppercase) focused on being really fast and powerful for server work. Either they expect to buy a company that has the expertise to reduce Power's power consumption or they expect one of these companies to license the design and do it themselves, though I'm not sure why Power's architecture is better enough than ARM's for such a company

              POWER has been been 64bit and massively out-of-order superscalar for years where ARM is only just beginning to enter the market. Simply put POWER is not in the same market as ARM, but in the same market as x86. Which means it is Intel (and AMD) who is killing them.

              • Ah, good point. Intel is way far ahead in low-power ILP/OOE, but they don't license their architecture, so yeah, there could be a market.

              • Simply put POWER is not in the same market as ARM, but in the same market as x86.

                Well, POWER covers a lot of ground. PowerPC is derived from POWER, and there have long been embedded PowerPC cores. The problem is that they worked on an old-world licensing model where each new product required a new license, and that license pretty much had to be negotiated with Motorola because that's who was doing low-power PowerPC.

          • Back when Apple first came out with PowerPC (the PowerPC 601 based 6100, 7100, 8100) the Ford EEC controllers were PowerPC 40x cores.

            We had "PowerPC Inside!" marketing stickers (I worked for the campus Apple Reseller) that i wanted to stick on random Ford cars for the hell of it. I never did, didn't want to screw up their paint jobs.

            Im sure there still are PowerPC applications in cars. And think of the 68000/DragonBall. A family that came out in 1979 but was sold until the 2000's as an embedded controller.

            Not only am I not defending PowerPC or POWER (I give a shit if it lives or dies, which hopefully will happen on its own merits, ha ha) but the PPC core in the 360 is not precisely the same as the one in the PS3, though they're based on the same design. The one in the PS3 is stripped down further and then glued to the vector units. The core in the 360 is faster, there's three of them, they are symmetric and they have slightly more features.

            • As far as I know, the only difference between the PPE and a Xenon core is that the later has a modified VMX (AltiVec) unit. They upgraded the vector register count to 128 per thread compared to 32 per thread on the PPE and they replaced a few vector instructions with others that are more useful in gaming.

    • From the perspective of most supercomputer users, the problem here is that you want to use something which is not Fortran or C. Very little hardcore numerical stuff is done outside of those two languages. I'm not saying that's a good thing, but it is the reason why there's so little incentive to have good compiler support.
