Quake3 to go SMP 168

Posted by Hemos from the fun-fun-fun dept.
schmack writes "Surfing the Id plans, John Carmack mentions he's working on SMP support for Quake 3. Although initially developed for NT, he says "it should definately make its way to the linux port...". Look for a speed up of 20% [worst case] to 80% in frame rate over a single CPU. This will mean "it will also be possible to build a reletively cheap SMP system (say, dual 400's) that outperforms the best single processor system." "

    Matrox G200 is about as close as you're going to get. It's still alpha/beta, though, and Matrox hasn't given out ALL the specs, so it's never going to be very fast, but it's the closest thing to what you describe (without buying stuff from a commercial driver vendor). Maybe NVidia will have a driver soon, and all will be well. About AGP, though, Intel refuses to release the specs on that, so you stand no chance of using it unless you're on a VIA chipset (even then there's no actual support yet, just specs)
  • I thought Carmack already posted something explaining that the gain would be too small to warrant an SMP version and abandoned his previous attempt.

    But, this does look authentic. Perhaps someone can help me out. I truly seem to remember some months ago carmack suggesting and then abandoning SMP support for Q3. Am i crazy?

    Voodoo [1,2,3] cards are all 3D only accelerators. You must have a 2d card in order to have 2d graphics :) (well actually there *are* XFree drivers so that you can use a voodoo2 as a 2d card but there is no reason to do this unless you only have 2 voodoo2's.) A combination voodoo2 (called Voodoo2 SLI) is where the voodoo2's are combined for a higher frame rate and greater resolution. A single voodoo2 can only do 800x600 @ so many frames per second (limited by your CPU). A voodoo2 SLI allows you to nearly double (again depending on your system) your frame rates and run quake for instance in 1024x768. A voodoo3 allows you to run 1024x768 also. Again, voodoo2 SLI does not necessarily mean twice the fps (frames per second) or resolution. If you have a 450 MHz or 500+ then you will reach the limit of the voodoo2 series. I'm not sure what maxes out the voodoo3 line or which one. There are multiple different types of voodoo3's...both PCI and AGP versions as well. I would be wary of the voodoo[1,2,3] line because of the 16 bit colors. Take a good look at the TNT2 cards. They are 32 bit color and are better. The trade off is of course the drivers. Not as many people support the TNT2 and most everyone supports voodoo[1,2,3]. Case in point is the Quake3Arena test which when it first came out would only run on 3DFX chips (voodoo series). The diamond v770 ultra TNT2 is rumored to be fully supported by Linux because diamond is working with XFree86. I wouldn't hold my breath though. Check out www.sharkyextreme.com for an article on the hurcules TNT2 card. For any hardware need, no one beats: www.tomshardware.com

    In true /. style the "story" is incomplete: Carmack goes on to say "I know SMP is a que for all the BeOS folks to ask about ports, so I'm going to head that off: Be has all the code for Q3 (and Q2, for that matter), and a version of Q3test should be available by the time they ship a release OS with OpenGL hardware acceleration. "

    This release is due in the next 3-4 weeks BTW so hopefully a month from now we'll be playing SMP Quake 2&3 on BeOS. Apparently a basic quick and dirty Quake->BeOS port was done in 1 day, and the full port in a week. I don't know if this was a port to a UNIX-like single thread process or if it takes advantage of any of the BeOS features. However given the ease of use of the Be API im sure it will be relatively easy to at least divide the rendering into 2 or more threads to take advantage of SMP.

  • So then how do you explain why all the video card manufacturers are now coming out with OpenGL drivers? I'm sure it's not M$ pushing them to do it. Quite the contrary, M$ wants to push Direct3D. ID broke the ice with glquake, and ID's games and derivatives have had enough market share to get the video card manufacturer's attention. Add to that Carmack's donation to the Mesa project, and I'd say that one single game comany is making a change in the industry.

  • After getting past the "Cool" response above, I thought a little more...

    If the underlying OS supports SMP and is written to a threaded model, then any application running on top of it is going to benefit from the extra horsepower - moreso if the app itself is also threaded...

    I can't believe that JC didn't write Q3 using threads, so is the new version going to subvert the OS's thread-to-CPU allocation process, or what?

    Any thoughts?

  • IIRC, JC tried to dedicate one CPU to "game" and the other to "render", but the overhead of pushing state information around ate up any performance gains, and then some...

  • What I was trying to say (but missed out half a sentence) is that all the other "background" OS stuff, like the disk I/O, network stack, and perhaps even the video driver will get to run without the OS having to interfere with the game.

    The only problem when going dual is that you have to use the lowest working frequence of your CPUs.

    So if you have 70% chances of getting your overclocked CPU to run at a given frequency, you will have only 49% to get a dual running at the same speed.

  • Linux runs great overclocked, if the hardware is stable. I've got a PII-266 chip that's been running at 300 MHz (4x75) for at least 8 or 9 months now with no problems. It got a bit flakey at 333, but 300 is perfectly stable. Seriously considering picking up a second 266 and a dual motherboard and overclocking them both to 300. Problem is finding that second 266... doh!
  • Even if the app itself is single-threaded, the rest of the OS is multithreaded. That means that the OS can be processing tasks on the 2nd CPU while the app runs on the 1st. Granted, it's not as good as a multithreaded app, but there is still an overall speed improvement because the app can truly own a CPU. In a non-SMP system, the app has to share the CPU with the rest of the system.

  • There are Intel HX socket 7 boards that can do SMP with intel chips.

    As for Super7, according to Via's website, the(M)VP3 supports SMP - presumably Intel's MP standard, but no board maker has ever implemented it.

    The K6 supports SMP aswell, or rather it is OpenPIC compliant. But there are no socket7 boards that implement it. OpenPIC is cross platform however, and is used on PowerPC SMP boards. Also, Digital Equipment was another developer of OpenPIC, so it's possible that they implemented it somewhere as well.

    (what kind of PIC standard does the Alpha 21164 adhere to - anyone know?)
  • AFAIK:

    Intel implements the PIC on P6's on the CPU core. Previously on socket7 the interrupt controller was integrated into the chipset. (and before PIC's got integrated they were a seperate chip).

    OpenPIC specifies an external PIC, so as long as a CPU can work with an external PIC, then that CPU is SMP capable with openpic.

    So if the K6 works now with the PIC in your Via/intel/ALi chipset, there's no reason it shouldn't work with an OpenPIC compliant PIC. The K6 doesn't need to care much that the PIC is also interrupting a second/third/fourth CPU.

    the K6-III would make a great SMP chip i think. The problem with Socket7 SMP was always the shared L2 cache. But with k6-III you have an even better cache structure than P6 SMP, ie fast, chip specific L2 cache, plus a large global cache - P6 SMP lacks a global L3 cache.

    just a shame no super7 chipset maker wants to build OpenPIc into their chipset.

    ah well...

    No. Your statement applies only if the app is multithreaded. If the original app is not multithreaded (or multi-heavyweight-process'd), then it cannot make use of the extra processor. If there is only one process (heavy- or light-weight), then the scheduler will only place it on one processor. Any other processes might be executed on the other processor, but I doubt many people are going to be executing another CPU-intensive app while playing Quake.

  • Bohn's first rule for scalability. If you're worried about bottlenecking the master node, try not to have a master node -- decentralize the supervisor functions.
    I suppose you could try to set up a QuakeWorld server on a cluster. If you're going to think in terms of "objects," though, you might be better off using a shared-object library such as a CORBA implementation instead of an MPI implementation.
    I also think you'd be smart to be careful about how you distribute the "world" -- a static distribution would make poor use of the processors (consider the case where all players are in the same general part of the world). But you don't want to go overboard with dynamic distribution ... set some minimum grain to avoid conjesting the network. I think a single room would be the absolute minimum.

  • Beowulf clustering would make sense for a large Quake world, would it not? It should be relativly easy to divide up the world on different nodes and use MPI to only pass the objects that affect the current node. The only bad thing would be the network bottleneck of the "master" machine.

    Would be interesting to see something like this, kind of like Ultima Online, only as a FPS.


    Just a thought..
  • The popular Voodoo 1 and 2 cards are 3DFX accelerators... meaning, they work in conjunction with regular video cards to do all the nifty 3D rendering and so on... what he said about using 2 Voodoo2's is called SLI (i forget what the anacronym stands for, maybe someone can inform), and that's where you basically use 2 3DFX accelerators that work together to do all the 3D rendering... This makes for quite a nice setup...
    However, the Voodoo3's are a 3DFX accelerator and a regular 2D video card all-in-one combo card. Personally, I'll stick with Voodoo2 for now for the opportunity to add another in SLI for 24 MB of video RAM goodness...
    There are other great/decent/good 3DFX accelerators/cards out there like NVidia's stuff, but I won't get into that since you just mentioned Voodoo's....

  • I've got three PCs running AGP cards just fine. AFAIK, AGP looks the same as PCI to Linux, only faster.


    True. However, if I understand correctly, you won't be able to use system memory for texturing without explicit AGP support. This is one of the primary benefits of AGP (especially with cards that let you read triangle setup data from AGP memory; bus-limit bottlenecks just got a lot wider).


    I don't know what kind of support this requires OS-side, but the previous post implied that AGP chipset specs are needed. Certainly the OS needs to be able to lock and unlock sections of memory for use with AGP. The graphics-card side AGP support isn't a problem if you have proper specs for the card (though that's a big "if").

  • Seems to me, if this kind of stuff catches on...

    2 K6-2 300s = ~$100
    1 P2 400 = ~$200

  • Heroes of Might and Magic 3 is the only reason why my PC at home now has 64 megs of ram instead of 32. ;)
  • I know you can't SMP Amd processors, that is why I took the time to reply to my own message, correcting myself.

    I still say it makes sense.
  • Amptron makes some inexpensive and from what I hear pretty good single and dual Slot 1 boards.
  • Win 98 isnt multi threaded like NT is. Don't plug in a second CPU into a Win 98 system unless you want a naughty kernel failure.
  • The problem is, in a game like quake, you can split off things like network communications, and other little shit like that, but it is hard to split up the process (meaning thing you're doing, not a 'user space process') that does most of the work: taking a memory representation of where things are and converting that into rendering information, and the CPU does have to help render some, even on a system with mad-assed cool 3d accelleration. Granted it can be done, as Carmack's success attests, but as you see, you can never do a full 50/50 split of the processor time, so you're very unlikely to get a 100% performance increase (even if there weren't any bacground/OS tasks running at the same time)
  • I agree. Although, I can see "needing" hardware dedicated to 3D. It involves a lot of floating point (well, fixed point if you really want speed) math and some trig.

    As far as bad code, I think it may be more of "Well, now most people have 200MHz machines... we don't need to spend so much time optimizing." Of course, having faster machines means getting you existing code to fly rather than an opportunity to become lazy.
  • Well id Software with Hovertank (and actually Wolf3d) did create the FPS popularity and thus all this stuff about 3D cards and extremely large multiplayer matches and such. It took a while to get the ball rolling, but id did the pushing.

  • It's a bit surprising that the app isn't multithreaded. I haven't played Quake 3, and I hear that it's all net-play (e.g. no AI opponents) but I would still expect that there's plenty of things to parallelize. I guess Carmack never bothered to deal with it -- but now he is!! Hooray!

    I guess multithreading would have made more sense back before 3D hardware was common and the CPU had to draw everything. I always though Wolf3D would really fly if only I had a CPU to raycast every pixel. ;-)

    This is actually extremely cool, as it should draw more attention to SMP systems. If SMP gets a bit more entranched, multithreaded apps will become the norm. :-) Seriously, "little" things like this are what causes long-term trends. The x86 would probably be a thing of the past if it weren't for Id Software's earlier titles. ;-P

    Parallelism (and 3D processors are really just a specialized case of it) is seen by many to be "the final frontier" and the only other significant way to make computers faster. Everybody's known it for years, but the mainstream never got around to embracing it. So the computer dudes had to trick us into it, little by little. They started with simple things, like the Amiga's blitter, which made the computer seem a lot faster than it really was. Then DSPs got a bit popular for a while, and then 3D processors. Now we're at the logical conclusion for coprocessors, where the "coprocessors" are really just general-purpose processors, and they don't have to hide it anymore, since Id is doing it. If a mainstream company like Id is doing it, then the point-haired folks will finally accept it.

    It's not really any more scary than the "fact" that the games next year will require a faster machine than the one you have today.

  • Tekram has a decent dual board thats about $170, and claims to work up to dual 700mhz p3's. its also got an award bios which i like very much. I don't remember the product code, but its their only dual board.


  • They really do *everything* right.
    - Release the source of old games.
    - Port to Linux/Mac/BeOS/Irix.
    - Piss of Microsoft by using OpenGL. ;)
    - Make decent games.
    - And now, do SMP.

    Me like ID Software. Great people do great things.
  • What are you talking about, this is great. This is allowing me to build a cheap dual-celeron 450 and get better than Pentium-3 performance. (under $500 w/SCSI3 on board for MB+CPUs)

    SMP is great.
  • If you were working in game programming around the time that Direct3D came out, you would been yelled at by Alex St. John about how much better Direct3D's brain dead "Execute Buffer" scheme was than OpenGL. If it wasn't for Chris Hecker at M$ and John Carmack, OpenGL wouldn't be nearly as well supported as it is today, despite being superior in EVERY way to Direct3D. Funny side note: In D3D v5, they ditched execute buffers for a OpenGL style interface, but they couldn't admit ogl was better and start using that, they had to clone it (poorly) and use that. Microsoft set the 3D gaming world back by at least a year.
  • Nope.

    They don't exist. However, the K7 should make a limited appearance in June.
  • Linux doesn't run any worse overclocked than Win95/98 (the crash standard). Linux will do an abrupt reboot if the processor is incorrectly overclocked. Win95/98 will hang or crash during boot. WinNT will give a BSOD before it gets to the log-in prompt. I know this because I had my Celeron333 improperly o'c to 500 before I saw the SharkyExtreme [sharkyextreme.com] way of properly overclocking a Celeron. Now, I can watch full screen Quicktime 4.0 trailers without skipping. (Oh yeah, those new Linux kernels compile rather rapidly, too...)
  • So you grab and OC 2 Celery 300As to 450, pop in two PGP(?) linked Ultra TNT2s to further accelerate the system, a 3d PCI sound card to deal with all the sound effects and processing, and pop in Quake3Arena at 1600x1280 or something...

    *Should* be playable. Otherwise, just drop down to 1280x1024 or something =)

    Gosh, but this is so incredibly cool.

  • I have to agree with Psiren...I admit my system is a little outdated, but I don't have the cash to be continuously running out to buy the latest and greatest in hardware just so that I can play a game. Don't get me wrong, I love to play Quake, but I think the thought of a game this day and age *requiring* multiple processors is a pretty scary thought (and possibly a little costly depending on where you shop and what you buy).

  • I have to admit, the possibility of Quake3 on a quad G4 is a good enough reason for Johnnie to support SMP.
  • I'm seriously considering buying a dual-cpu motherboard in my next PC. The only thing is, I don't want to use Windows NT! Hardly any games run on it, and it's slowwwww. Heh...maybe if I could dual boot 98 and NT I could justify a 2-cpu gaming machine...
  • Seeing as I just bought a new 19", my old 15" can now have a purpose! Well...the game looks better on 19"...and I won't be paying any attention to the non-quake screen...but it'll still be cool have 2 monitors! woohoo!

  • SLI (Score:1)

    by ioctl ( 19935 )
    SLI stands for Scan Line Interleave. One card gets a scan line, the other the next, then the first gets the next after that, ad infinitum. It's effectively like having a single card with 4 texture units on it, each having their own private 4 megs of texture memory. And I agree, voodoo2 SLI is the way to go right now, if you can afford it.
  • As far as I can tell, it doesn't have all the
    instructions necessary for a full accelerated opengl. I ran quake 2 with it, and it seems to slow to a crawl whenever there is a muzzleflash on the screen.
  • Form follows function.

    Id graphics were created on SGI, pre-playing & testing the games on a PC with an OpenGL video card was a natural.

    It wasn't a virtue of Id, just plain laziness.

  • It is important that a system match the job it is tasked with.

    If networking doen't cause too much latency, then often a network of single processor machines is easier than one multiprocessor machine.

    Depends on the appliation.

  • Hmm quakeIII with SMP support for linux and NT. Looks like one of these two systems due to this fact alone could become the new gaming standard. (assuming rumors of hardware support are true) Guess which one.. I'll give you 2 guesses and the first one doesn't count

  • I had two PII333's overclocked to 500 running smoothyly until my peltiers dripped on my board :(
    I had them at standard 2.0volts- they seem to need to be at 2.3 volts with a little bit of a load to keep them warm enough so the condensation doesnt form - doh!

    For the moment Im now running one in a cheap bx6v2 board and have no problems -

    Im thinking of gettting that cheap mother board that the power 2 u dude PC uses - EPOX EP-KP6-BS and sticking both of them in again.

    I haven't read up on the slockets - Is there a slot adapter for basically just doing the voltage? (IE my cards are already slot 1 and dual capable - but I don't want to tape any pins.)




  • Are you sure you're not thinking of tnt2 drivers for linux? I remember that one a couple weeks ago on ./ but not anyting on voodoo3.

  • NT, if you have enough ram (at least 64MB, 128 is better) is slightly faster than 9x on the same machine.
  • Does anybody know of any super 7 smp boards? Is there even a chipset that can do that?
  • Really? Why would that be? Something to do with the adapters?

    I was running dual P2300s on an FX chipset until one cpu died, so I decided to upgrade to a BX board and give the PPGA with converter thing an option. 65$ for each PPGA (300a) about 120$ for adapters, cooling, and shipping (might not have been the best price, but seemed fair (www.computernerd.com)). I plugged the PPGAs into the adapters and booted up to make sure everything worked. It did. I shut down, jumpered the MB to 100mHz, rebooted and have been running dual 300a PPGAs at 450mHz for a couple of weeks now without any problems. CPU temp rarely gets above 30C and is usually 1-2C above the MB temp (although I'm not sure how the cpu temp is being measured, which goes to show that I'm no hardware guy!)

    All in all, I couldn't be happier. I guess if I got it done for less maybe... Only thing that would have made it easier would be for someone to come in and do it for me, but that's not as fun. :)

    From my point of view the fact that SMP is not being used more is what's insane (and not just in games, I think it should be almost everywhere...I'm nuts, though, so take that with a grain of salt). You can make use of cheaper CPU's and get better performance (depending on what you're doing of course, but I hope you see my point). Since PC's are used for so many different tasks at once, why not divide up the work? Even if app developers don't want to worry about threads, if the OS is designed to do the juggling you can experience much of the benefit.
  • > needing* multiple processors, just as it now

    Well, your 3d accelerator card IS another processor, just dedicated to graphics. Personally, I'm all for multiple processors. If I can load Linux on a Sun E4000 and use ten processors for the screen, one for the game logic, and one of everything else -- and get some sort of super-reality game, heck, sign me up!
  • > the *needing* of 3d acceleration can hardly

    For games to 'jump to the next level', you need new hardware. Quake and what not wouldn't be Quake without the 3D cards. We'd all be stuck playing Master of Orion or something. :)

    If taking advantage of new technology allows for a breakthrough in gaming... be it quality, complexity, or a complete new genre, go for it. It will only 'require' new hardware to the extent that the new hardware makes the entire thing possible.

    [However, games that require mulitprocessors for apparently no reason should be SHOT.]
  • Even better would be a network type environment where you could install a client on other machines throughout the office and to suck their idle CPU time from their systems and turn it into a hyper-reality gaming experience for you. :)

    "Don't use your computer's idle time to search for aliens... use it to kill them!" -- Quake's new marketing line.
  • You can't use the AMD processors in dual processor configurations. Intel uses a different interrupt controller (APIC) which lets them use multiple processor configurations.

    Umm, there IS support for Voodoo3 under Linux for both X-windows and Q3A. http://glide.xxedgexx.com has the goods. Daryll Strauss, the maintainer, just released a glide port for the V3 that the author says works with Q3A.

    There is now.

    Go back to http://glide.xxedgexx.com/status.html [xxedgexx.com], the Banshee/V3 glide libs were released on May 16th.

    At the moment it is fullscreen only, i.e. no rendering into a window, but that is being worked on.

    If you compile Mesa, you get OpenGL support too, and then you can run Xscreensaver with all those GL hacks! :)

  • SMP functionality for quake iii:arena was alluded
    to over a year ago. you may want to look at the
    may 19, 1999 update at

    http://www.scs.ryerson.ca/~h2jang/trinity.html

    for further details. and, yes, Carmack did
    later mention some disappointment about the
    "marginal" improvment of an n-processor
    configuration over a single processor machine. but that was many months ago ... earlier in his research.
