Universal Emulators Return 546

Posted by Hemos from the and-soon-lead-to-helium-3 dept.
webmilhouse writes "Wired has an article about Transitive Corporation that claims their software "allows any software application binary to run on any processor/operating system" without any performance hit. That would allow any program written for Windows to run on Linux or Mac, and vice-versa, which Wired likened to digital alchemy. The Transitive software is supposed to be released today. What do you think, vaporware or miracle?"

      Analyst Rob Enderle of the Enderle Group said Transitive benefits from the fact that most modern machines are fast enough to emulate each other without much affecting performance.

      "Typically with emulation you take a big performance hit," he said. "Their big breakthrough is they are much more efficient ... but there's so much overhead anyway, you can pretty much put any software on any platform. The power user might notice the difference, but the other 95 percent won't notice."


      so yes, it does affect performance. You take a 20% hit. The "almost no performance hit" means, in this context, "computers are fast enough that no one will notice unless they're doing something crazy like video editing. Go back to surfing slashdot."

      Yep, none of this is new tech. In fact, it's pretty old tech at this point. Emulators/translators and everything in between have been the subject of experimentation for decades.

      Actually, I expect to see someone sit down and write this for Parrot sometime soon. Especially of interest would be an S/390 emulator written in Parrot.

      Parrot, for those who don't know, is a VM that targets very high level languages, but it's flexible enough and has a sufficiently strong JIT compiler that a hardware emulator extension to Parrot could easily produce code that would perform as well as the described product.

      The cool part about writing such an emulator for Parrot is that you get access to the resulting emulated code from a number of high-level languages, so you could port over your S/390 airline application written in TPF and call its routines from a Java, Perl, Scheme or Ruby program, jumping into and out of hardware emulation as you go. While high-level languages would only have gross access to data as opaque objects, the hardware emulator could provide the ported code with everything that it expects.

      "Emulation" is a sophisticated art at this point, and it's going to get very interesting over the next few years.

      After reading the article, I personally see the whole issue as much ado about nothing. The quotes provided in the article leave me with the impression that those who were involved with the article had little experience with emulators or were quoted out of context. I think this is obvious given remarks like "One of the key breakthroughs is an 'intermediate representation'..." that imply revolutionary thinking when in fact the ideas are not new.

      I'm sure their product does whatever they designed it to do, but the article alludes to platform migration and operating system virtualization. This screams out to me that the emulated programs are going to be very well behaved out of necessity, and most hardware interfaces will not be accessable except through API calls. Additionally, desktop PC software and operating environments tend to be much more 'regular' than embedded systems like game consoles. It is much easier to describe the behavior of user-mode code on a platform with a generic memory space and API set than it is to describe the behavior of an embedded multiprocessor system with control registers, DMA, custom graphics and audio subsystems and banked memory.

      I also have to question the allegation that "no one has successfully developed an emulator for multiple processors and operating systems." Dynamic recompilation is not new. Intermediate representations are not new. Surely there exist some emulators which are capable of emitting multiple native instruction encodings in the backend. If none exist, I doubt it is because they are not capable of doing so.

      Describing a processor architecture and providing an API mapping is not a trivial task by any means. The Transitive tool doesn't just 'simply work,' its requires a massive undertaking to prepare the behavior descriptions that I imagine would be in some ways more difficult than writing an ad-hoc single-platform emulator. I think that calling their tool a "hardware virtualizer" is probably a good idea, but not because its faster than an "emulator," but more because its likely nowhere near as powerful as a system emulator.

      Finally, I would also beware the performance claims. Dynamic recompilation is certainly the way to go for ultimate performance, but when you generalize architectures, you often lose the ability to take advantage of native features. Also related to processor capabilities, the overhead incurred by emulation is highly correlated to the disparity between the host platform and the emulated platform. Transmeta processors suffer about 20% overhead and thats using a flexible VLIW architecture designed with x86 emulation in mind and using a dynamic recompiler that supports *only* x86. Thats a huge performance penalty, even if programs are running as fast as needed. Given the generalized emulation approach, I think its clear that the feasibility of such an approach is going to depend heavily on the host platform being more powerful/flexible than the emulated platform.

      FWIW, I am the author of Nuance, the Nuon emulator. Nuance currently performs all of the same feats listed in the article including block translation, optimization and 'OS' virtualization (native implementation of the Nuon BIOS). I'm currently working on emitting native code using a custom x86 run-time assembler and backpatch mechanism.

        It sounds like it is software that translates one machine language to another? Pretty sweet idea!

        There was a translation solution in place back in the early 90's: Apple was working with a company called Echo Logic (probably not in existence today; please don't /. the logical URL!), a spin-off of Bell Labs, that could convert 68K binaries to PowerPC as an approach to migration to PowerPC.

        I worked with them for a while to see if we could port our application (which would have required tons of work to re-compile for PowerPC); the technology was impressive, but aspects of our code gave it fits (trap patching, and dispatch tables that were effective self-modifying code).

        The EL technology identified code blocks in the binary, built an intermediate representation of all the effects of each code block, and translated it back to binaries in the target architecture. Theoretically feasible, but computationally very expensive. In some test cases, the translated code was in fact more efficient from the original, because the software was able to detect unused output of a code block, and re-code the block to eliminate the unused "side-effects."

        Ten+ years later, maybe somebody has more of the gnarly problems worked out. But I would bet there are issues that can't be solved with technology; i.e., the binary software on the "source" system. Presumably you can find and translate the system binaries to build a translated app, but wouldn't this constitute "reverse engineering" that most software licenses prohibit?

      Transitive explains the architechure of their system here [transitive.com]. Basically, to support APIs on different operating systems they have what is called an Operating System Mapper. They don't claim that it maps Mac to Windows or Linux to Windows. Basically, it maps two like systems together (like Solaris to AIX or HPUX to Linux). If there is no straightforward mapping then the customer defines the map.

      After reading this, the term Universal Emulator doesn't seem to apply. Here is the text from Transitive's Website:

      Operating System Mapper. Dynamite supports operating system mapping between any two Unix/Linux-like operating systems, as well as mapping between mainframe and any Unix/Linux-like operating systems. Where similar operating system calls exist between the source and destination operating system, Dynamite maps calls between the two. Where an equivalent operating system call doesn't exist in the target environment, Dynamite maps to similar calls per the customer's guidance. Dynamite also monitors certain system calls, for example thread scheduling and memory mapping calls, to ensure that it can reproduce the complete behaviour of the program it is executing.

      • Dynamite allows software that has been compiled for one processor/operating system to be run on another processor/operating system without any source code or binary changes. To do this, Dynamite provides a hardware virtualization technology that consists of four key components. First, an integration FUSE allows Dynamite to be easily integrated into the target system.

When my linux binary calls any given kernel, C library, or even other common library (readline?, pthreads?, opengl?, etc..), those calls all have to be translated to equivalent MacOS or Windows API calls.

    In demonstrations to press and analysts, the company has shown a graphically demanding game -- a Linux version of Quake III -- running on an Apple PowerBook

    Does this company realize that proper existing ports of each of those particular pieces of software exist in some kind of native form for those architectures? I've used GIMP in Windows w/ no problems. Also, as mentioned previosuly, Quake III already exists for the Mac as well. What good are they doing by using software that already exists in ports? I want to see a copy of some DirectX game running on a Mac/Linux w/o a performance hit. This company so far has not proven anything by using the two comparisons cited in the article.

      ... so that they can show the native version side-by-side with the translated version and show that there is no noticable hit in performance.

    It runs everything (1) on everything (2) without performance hit (3).

    (1) Uhm, err, the current version only runs Pacman, which required some modifications to the binary
    (2) only on Windows XP, but we're working on the Win 98 version.
    (3) The technology used allows for theoretical performance equal or even exceeding the native hardware. This will work in next version, "FlyingPig 6.0".

    there is mention only of unices. Operating System Mapper. Dynamite supports operating system mapping between any two Unix/Linux-like operating systems, as well as mapping between mainframe and any Unix/Linux-like operating systems. Don't see "Windows" mentioned in there. I assume it would be a lot easier to run a Linux version of Quake 3 on BSD-based Mac OS X than to convert stuff to/from a rather more different OS such as Windows.

    The summary should almost be modded flamebait for making such an obviously impossible statement like that.

    So what's really up here? TFA says they demonstrated running a Linux Quake III on a OS X powerbook.
    (And they quote Rob Enderle praising this technology.. this is the guy who thinks SCO will win [eweek.com], which speaks loads for his credibility.)

    Now, I haven't seen the source for Quake III, but I'm pretty certain it uses OpenGL, which the Mac has. OS X is also POSIX-compliant. So, most of the API calls done by Quake can already be done natively on OS X.

    So what I guess they're doing here is translating API calls (like Wine) while emulating the processor core (like a real emulator).

    That isn't anything new. For instance, I've written similar code for an Atari emulator [sourceforge.net], which can emulate an Atari hard-disc filesystem as a local directory through translating OS calls.

    (Note: And that was far from the first time it'd been done either.)

    Bottom line, a porcessor essentialy comes down to several basic comparisons and read/write add/subtract operations.

    so it is technicaly feasible that if you map out a fair amount of the pipelines of most of the popular chip sets, you could technicaly have a command chain to allow binaries the same calls through a sudo-emulation layer of the software.

    fundamentaly possible, and even do-able.... but without a performance hit? no way. Each processor is geared towards a particular way of solving a physcial and mathmatical set of problems... some processors are designed for massive loads of database driven calculations (XEONs)... some for multimedia (G5)... some for science (PPC, Sparc?)... some for power savings (ARM)....

    depedning on which archetecture your using, the performance will be greatly hindered if your trying to do something designed for a radicaly different chip. Such as trying to run some expansive G5 optimizied photoshop plug on a ARM chip.

    This is vaporware. What they're claiming - "without any performance hit" - is impossible. Accomplishing the rest of what they claim is not impossible, but it's very difficult, and since the "without any performance hit" claim establishes conclusively that these people are bullshitters, I don't believe they can even come close to doing it.

    The marketing jargon goes a bit over the top, but it isn't impossible to translate code for one ISA to an intermediate form, optimize it, and then generate code for another ISA. I don't know that it's revolutionary either. Note that LLVM [uiuc.edu] takes a similar approach, and has a very simple intermediate form. I hear someone on their team is working on a PPC front-end, and as for language front-ends, Java and C# is in the works.

    Getting back to Transitives, in July 2001 [businesswire.com], they claimed to already be doing x86->MIPS translation, which bodes well for x86->PPC. However, doing things efficiently the other way around is tougher. And of course you need to support or translate a ton of the native OS API calls etc. It'll be interesting to see for Windows on Linux (for example) if they require a copy of Windows to run the binaries.

    Because the past 2 generations of PowerBooks haven't been running on a BSD kernel which is very similar to *nix and runs most *nix applications natively anyway? Moreover, Quake III uses OpenGL as a renderer which makes ports a lot easier than games using DirectX.

    The graphic on Transitive's website [transitive.com] shows only Unix/Linux operating systems. One of their steps, Operating System Mapping, says "QuickTransit supports operating system mapping between any two Unix/Linux-like operating systems, as well as mapping between mainframe and any Unix/Linux-like operating systems." Doesn't sound like Windows to me.

    All of this is supposedly done on the fly, and not beforehand.

    Quake and The Gimp wouldn't be my choices to show off flexibility. Quake is OpenGL on Linux and OSX, so there isn't any graphics magic going on. And the ability of BSD-based systems to run Linux binaries is old hat. The Gimp isn't exactly taxing on a CPU as far as user responsiveness goes.

    Extraordinary claims require extraordinary proof. Press conferences for journalists aren't a conducive forum for proving anything. They are a good place to baffle 'em with bullshit, though.

    From the /. article:
    "...That would allow any program written for Windows to run on Linux or Mac, and vice-versa..."
    This is a bit misleading, because it's really a "one flavor of *nix on another flavor of *nix" system. Playing a Linux version of Quake III on an OSX Mac doesn't seem like rocket science because of OSX's native BSD roots.

    I'll wager that if I took something like "Quicken" or "Microsoft Office Professional" for Windows and tried to run it on a Mac running QuickTransit that it certainly wouldn't work. I doubt if iMovie would run on a QuickTransit-enabled PC. THAT, my friends is the "computer-alchemy" goal. Of course, I would LOVE to be proven wrong on this!

    Now, if they are talking about "any program written for Windows [that adheres to QuickTransit Requirements] to run on Linux..." then they may be accurate, but again, this really isn't "universal emulation".
