Quad G4 Boards
su-geek writes " Synergy Microsystems offers QUAD G4 boards as well as QUAD G3 boards which all run SMP linux. Not only that but you can add more than one board to the dual PCI backplane." I didn't find any evidence of running Linux, and they don't appear to be motherboards: they look like addons, but still, they look nifty. I want a couple CPUs dedicated to running OpenGL screensavers in my root window or something.
For those of you who want to know more about how to go about putting together a working system with Linux and VMEbus components, see www.vmelinux.org.
From their site:
This project's primary offering is the Kernel Level Linux Device Driver that interfaces between the Unix Shell environment and the VMEbus. The driver is compatible with the Tundra Universe PCI-VME bridge integrated circuit.
Those things don't look like motherboards because they aren't. The VME and CompactPCI bus are industrial grade busses. The Synergy Micro boards are "Single Board Computers" that plug into a bus and control the boards that plug into other slots of the bus. These other boards can be anything from digital I/O for controlling machines, to video interfaces for machine vision applications. These systems go into applications for which your desktop PC (or Mac) would quickly fail. For example, my company is bidding on a project with a requirement that the boards in a CompactPCI (or is it VME, I forgot) withstand accelerations of 20G AND be able to survive being cleaned with a fire hose!
Okay, first off, what is it?
This isn't a motherboard, it's not a PC, it's not some piece of trash laptop component. This is a very very powerful VME board. Industrial computing only - no, you can't afford the chassis to hold it. It's usually in the $20k+ range for a basic VME chassis able to handle this type of board, assuming I'm looking at my current pricing sheet. (I don't think it is, but it can't be that much cheaper.)
Now, it says it'll run VxWorks. Linux isn't on there. And I wouldn't waste my time - Linux won't work on it. Unless somebody's been REAL busy with the PPC tree, FORGET IT. PERIOD. END OF ARGUMENT HERE. Don't bother flaming me, I'll be more than happy to just delete it. LINUX DOES NOT RUN CORRECTLY ON SMP POWERPC AND HAS NOT FOR MANY MANY MANY MANY MANY MANY VERSIONS. For a VERY long time, it wouldn't even run on two processors. And when it did, there was *exponential* performance degredation on multiple processor systems. And now you think that MAGICALLY you're going to use *FOUR* PowerPC 750's (NOT G3s) with Linux? If it wasn't Slashdot, I wouldn't believe the incompetence and idiocy of claiming to run Linux.
And as if THAT weren't enough reasons, did we mention that LINUX DOES NOT SUPPORT VME? Last I checked, Linux doesn't even support CompactPCI! And somehow you're going to just run Linux on this? Give me a goddamn break. LynxOS won't even run on this, unless they've added VME support. That's why it says "VxWorks" and not "Linux" and not "Windows." The fanatics need to get their heads out of their rectums and realize that every time they make some blanket statement crap like this, they only make an ass of themselves.
This board doesn't even have a controller - what, you're going to magically plug in a SCSI disk to the chipset directly? The board boots and runs off of NVRAM Flash. This isn't some cracked-up PC. This is INDUSTRIAL equipment. How do I know these things? Probably because I have a CompactPCI (similar to VME somewhat) system built out for engine and onboard computer diagnostics and tuning. How much did it cost? I lease for a reason. What's it run? Not Linux, that's for damn sure. It runs LynxOS for a reason - not only because Linux isn't fit for the job (shut your mouths, zealots. I don't see any powerband analysis software for Linux any time soon.) but because LynxOS is *designed* for things like this.
Guess I probably pissed a lot of people off. Good. Maybe those of you who were offended by my comments will shut up, get your heads out of the clouds, and come back to earth sometime this year. Linux is not the do-everything OS, and it never will be at this rate. With supporters that claim it can do anything without any proof to back it up, and claiming it incorrectly half the time, I don't see any profit for ANYONE from it anytime soon. RedHat's stock isn't trading at 26 for no reason at all.
With supporters like this, I think I'll support FreeBSD instead. At least they have some respectability left.
