Cell Workstations in 2005 330

Posted by michael from the it-slices-it-dices dept.
yerdaddie writes "The cell processor will be introduced in graphics workstations before release in the Playstation 3, according to press releases by IBM and Sony. As previously discussed, IBM will be releasing more details in February 2005. However, apparently prototype workstations have already been "powered-on" and will be available in 2005. Since Windows on PPC was scrapped back in 1997, this leads to speculation that perhaps Linux, AIX, or BSD will be the operating system for cell workstations."

      It has been stated before [psreporter.com] that the PlayStation 3 is expected to be capable of distributed processing [webopedia.com] due to the capabilities of the Cell architecture. Whether or not that will indeed be the case remains to be seen, it is certainly a lofty goal for the current market penetration (not to mention speeds) of broadband in the home. Does Sony expect these PS3s to cooperate with their Cell-based television sets?

        The stated goal is for some future playstation (maybe the fourth generation) to use the cell processor and yes, to cooperate with cell devices in televisions, dvd players, et cetera. If we end up with cell PCs they'll be candidates too. They could run linux, of course. To be honest, that's the Xbox, if it were clustering, and it could have been if there were any reason for it to be. Sony will probably use some kind of IEE1394 (i.Link in Sony's parlance) possibly including 800Mbps in order to connect Cell devices. 1394 allows significant cable lengths and near-gigabit speeds today; it is intended to support 1.6Gbps and later even 3.2Gbps (over fiber.)

        Do people actually believe this (tr)hype? Were you the same people actually getting giddy about the awfully named "Emotion Engine" allowing realistic hair or somehow providing better human reactions to characters in 1999?

        Console games work and develop well because of one thing: standardization of platform. If you put your game in any console of the same type, it will run the same (besides various regional differences (PAL, NTSC) and maybe some hardware changes later on in a production run, ala XBox's two DVD drives)

        You do not design for "potential extra processing" from someone's TV, toaster, aibo, or whatever. You design for the LCD, which is the unit that everyone buys. You might be able to take advantage of extra hardware like voice headsets or harddrives, but even then your game has to work well without it. (Example: Xbox allows you to precache data from the DVD on the harddrive, but you still need to be able to meet loading time standards without it. i.e. you can do better than 15 seconds with the harddrive, but no worse than without).

        Can you imagine the testing nightmare of "better AI" if someone has a Sony DVD player nearby? Do you test every level with every combination of chip configuration out there?

        This of course has been written with the thought that this is at all possible. Well, sorry, it isn't, and the super IBM cell processor isn't going to make it so. Console games work off extremely hard deadlines, and that's the refresh rate on your TV. Every 16 or 32 ms you need to have a new frame rendered and ready to go. You can't schedule a few frames for processing on the microwave and ask for them back whenever. What your drawing depends on the real state of user input, ai, physics, lighting, scripted events, etc. The state of the game at any point in the future is unknown, and thus in those 16 ms you have to figure out what needs to be updated, how the world should change, and finally render that to the screen. The actual rendering time might not even be half of the time you have for a frame. Do you have the bandwidth to send that data out and expect it back in the same frame? If so let me know so I can get some of that!

        I could see remote AI processing, MAYBE, but that still has to be able to be done on the console anyways for the LCD case. AI is one of the worst things to debug in game development as a lot of times it can be non-deterministic. You do not want to throw another variable into the testing, especially not when its hardware.

        Sony has a very good marketing department for continuing to push this crap. They've said "we will use this cell technology in other products besides the PS2" and "In the future the PS platform will interact with other Sony brand components", thus meaning that maybe your PS2 can start popping popcorn or something, but that has nothing to do with processing, its just networking. But somehow the two get combined on fan sites to mean "OMG, buy 28 PS3s and Jaxter and Dax runs at 6000FPS!!!"

        What you will see with cell processing is a continuation of the mulitprocessor platform the PS2 had, but in a more generic sense. This should allow very interesting stuff to be done, and while games will be initially harder to develop, there's going to be some really cool stuff coming out of this. But don't believe you're going to suddenly see a sentient household that's drawing a few extra pixels in GTA VI: The Quest for More Money.

      I may be wrong, but to me this sounds like hyper threading with a new name. Can anybody enlighten me?

      It's not the same. Hyper threading divides processor units (e.g. a multiplier or an adder) in order to keep most units of the single core busy. This happens because Intel processors have very long processing pipelines (thus the very high frequency compared to AMD), so stalling them can be quite costly. In order to avoid this, Intel simply keeps track of two "virtual" processor states, essentially 2 copies of all registers, and schedules instructions from any of these two execution threads in ways that keep most units busy. By chosing from 2 threads instead of one it has greater chances of finding an instruction that can be computed by an idle (at that time) unit.

      Cell architecture, on the other hand, seems to rely on multiple simple cores, each of which is complete. A central Power processor core keeps them working together. I assume (but I do not know!) that the benefit of this architecture is : (a) adding multiple cores is easy and increases cost linearly (b) software that works for a 16-core chip will also work for a 2-core chip, but slower (therefore the same processor can be adapted to different needs, just like multi-unit videocards, without expensive redesign) (c) an inherent understanding of parallelism (on the chip) allows chaining them together in an easy fashion. Maybe we will start counting cores instead of MHz in a few years, when all cpus will have peaked at some--obscenely high--MHz limit. Details on the cell chip are very vague and ridden with marketing buzz-words, but it appears it will be able to execute many more parallel threads than an Intel HT processor (2 threads maximum in parallel).

      What worries me most is the fact that Sony (which also sells music/movies etc) says it'll have on-chip capability to protect copyrighted works. I don't know what this will mean for the GNU/linux crowd.

      Disclaimer: All the above is wild speculation. I am not an engineer.

        From what I've read about the Cell line, each core can run its own kernel (i.e. it doesn't have to). This provides some interesting possibilities, for example a general purpose kernel running on one, while a real-time kernel runs on another and handles things like sound. Current systems have to make a choice when it comes to scheduling algorithms:
        1. Make one that works for all (or, at least, most) cases but is hideously complicated, or
        2. Make one that focusses on one class of application (e.g. throughput-oriented, realtime, etc).
        Most monolithic kernels choose 1. Several micro-kernels implement the scheduling algorithms in user-space, allowing them to be swapped easily. Having a large number of cores available to the system would allow this to be dynamically tweaked.

        This approach seems more in line with the exokernel project than any microkernel I've looked at. If you've got some spare time, exokernel is well worth a look.

      • But it will be a micro-kernel that will be rather small. You'll have cell processors for doing processing work, then other cell processors acting as I/O controllers with their own kernel.

        Think outside the box, equating the cell design to existing PC architecture is silly.

        Besides, you said it was wasteful? aren't many clusters built of entire computers where you have display hardware, floppy drives, hard disk, RAM etc...?

      What's interesting is that how Sony and Microsoft handle their product launches may have an impact on the amount of games we see for these systems. With Linux gaining ground on the desktop (bear with me here), it is concievable that it might be a larger target for games, if not gaming development on a 64-bit workstation. Epic have already committed to an Unreal Tournament development platform on Linux (Windows 64-bit taking its time is probably also a factor).

      The most interesting part, however, is that MS may be putting up .NET as the development environment for the X-Box 2. It makes sense that MS would try to leverage their gaming platform to lure developers onto the .NET platform and commit their engines to that API.

      On another note, could Linux and Mono play much of a role in this if the Cell does indeed provide a Linux environment for development? If Sony is able to provide a less expensive development environment, development costs may ultimately go down and the consumer would benefit.

      This could be either by the increase of choice since the bar of entry would be lowered for smaller software houses, or by cost if the games are indeed cheaper as a result; Existing engines and software could be ported or would be compatible, or due to the the ease of coding on a familiar platform.

And their software took years to write and it still is not 100% correct. (they still have some bugs in the x86 emulation) It's not going to be easy to do such a thing and at the end of the day what would be the advantage of running emulation at that level when you can just run a user level process to emulate a PIC, or ultrasparc or whatever you want?

      Even if you could emulate an ultrasparc cpu, you can't just throw it into a PC case and boot solaris, you have to use an actual SUN computer that has the right video, network and ide cards in it otherwise you'll have a broken machine. There are lots of little things that will cause the machine to break. The cpu is the heart of a computer, but it's not the only piece. They all have to fit together or it won't work.

That I have no doubt, what I do doubt if microsoft will consider this important/the future and if they'll support it during the inital release (w/ longhorn maybe?) or if they'll come late and lose a large section of the market as we all jump and have to use a *nix as the desktop.

    If this whole cell thing is more then hype, and is the wave of the future, Microsoft will support it.

      NT was amazing because it was designed from the ground up because it could basically be compiled for any endian chip/any aritecture

      I don't think NT supported any big-endian platforms. Even on PowerPC it ran in little-endian mode. Porting to a new platform was not quite a straight recompile, but it did only require porting the HAL, not the entire system. OS X works in a similar way - the Mach microkernel is used as a HAL (which is how NeXTStep ran on so many architectures with such relative ease).

    What'd I'd like to know is what IBM's solution to the software problem is. Software has always been the achilles heel of multiprocessor systems. Most existing programs and even most existing programmers can't use the resources efficiently. That's why we have gargantuan superscaler, out of order processors. Expensive in terms of hardware but it suits the software better.

    So, why is Cell going to be easy to program, when other parallel systems aren't? The bits of that i've seen about the architecure suggests that programming might be an absolute bear.

    I'm still a bit worried that I've not heard much about the seemingly built-in DRM management of this new platform (that seem to be able to spread to all facets of technology, including toasters). According to a clause in the pressrelease by IBM and Sony from Nov. 29 [ibm.com], the Cell processor will have:

    - On-chip hardware in support of security system for intellectual property protection.

      Not necessarily. There is no indication of what is meant by "hardware in support of security".

    Nothing's official just yet, but this is WAY more interesting than studying for finals, so here we go:

    Processor instructions are broken into an 'apulet', which contains data as well as code to perform an operation. This is probably why its claimed that if more processing power is needed, then its a simple task to add a new workstation and the work can be offloaded.

    A cursory read suggests that its like creating a cluster of highly efficient yet simple nodes.

    Corrections are welcome.

      And how apulets are going to be extracted from serially executed code produced by a C compiler? Will the applications need to be written explicitely for Cell?

      The idea behind the Cell processor is a good one...it is not entirely different than what the Transputer did 15 years ago. Transputer CPUs could be connected into a grid, and the processing power multiplied accordingly, but with one assumption:

      code should have been written in a special programming language that allowed easy parallelization of code.

      The idea of Transputers failed because it is highly difficult to extract parallelism from code. Special development tools were not available.

      The PowerVR architecture also promised 'infinite' 3d graphics speed by just adding new GPUs, since it used tile rendering, but that failed, too.

    This seems like an excellent opportunity for Apple to license Mac OS X.

    I'm assuming the intruction set for the cell processor is a superset of the existing PowerPC processors, or that the missing instructions could easily be emulated. If so that would make this is a graphics workstation that could run Photoshop, Final Cut Pro, Shake, and other top notch professional software immediately. The existing user base wouldn't have to buy new versions -- their old versions would run.

    As discussed many times on slashdot and elsewhere, Apple won't license their OS unless they believe they can do it without cannibalizing their existing user base. Doubtless there would be some cannibalization of the high end, but if it makes OS X the clear platform for high-end graphics workstations it could still be an overall boost to Apple. I don't really know how the current high-end graphics market sees OS X. My impression is that a surprising amount of it is on Windows, and that Apple is just holding on to its market share in this area.

    Anyone with more current knowledge of the high-end graphics market care to comment?
