Portable 8-iMac Linux Cluster Real World Debut

Snocone writes: "Here is the first real world application (researching drug effects on the brain, ironically enough) of Terra Soft's 8-way Black Lab Linux cluster. Even if they didn't deserve mad props for standing up proudly against the Lintel hegemony, there's just something fundamentally hilarious about selling an $18K supercomputer made out of iMacs." So - eight Imacs. You could get the different colors, and call it a Lifesavers Candy Cluster?

    If you read apples page about the G4, it used to have (this is PRE dual g4 powermacs, but G4 none the less) a lot of articles there about using it in science. Like how it has the lowest Gigaflop per dollar or something IIRC.
    take a look:

    And the iMacs are developed for the cluster because they are small, netbootable, and boards can have a G4 upgrade put on them.

    For the last time...there is nothing in the GPL which requires a GPL'd product to be free. It just requires that you make the source available to people who purchase the product, and that you allow them to do whatever they want with such source. If you're so damn concerned about it, cough up the $389 and make "Tangent Z's clustering linux-o-rama" and put it up on a public ftp site or something.

    Registers to aid cross-network IPv6 shared memory? Let's see some white papers from MOT here. Does the G4 implement IPv6 in the processor? Yeah, right.

    So, I could possibly see how MOT has some registers that are sort of doing the Intel thing... You know, the Intel Net Pipeline. The one that makes the Internet faster. Just like the Motorola DSM registers?

    And it will take a LONG time before I'm convinced that your Apple iFruit can replace my Ultra Enterprise Server. I don't care if it's running BSD underneath, Apple has a LONG way to go before I'm convinced I should use an Apple product anywhere in an environment that is anywhere near mission-critical or secure.

    Companies have to earn their respect. Apple has not yet made a server OS. It will take a long time of them having a good server OS for me to be convinced that I should use it.

    I've heard gcc doesn't produce very well optimized code for the PPC architecture.

  8. Wouldn't the G4 be a better option? by JanKotz · · Score: 3

    Those new cubes are proof enough that you can cram lots of PowerPC hardware into a really tiny space (without lots of fans, either). Furthermore, Altivec should make the G4 absolutely CRUSH any G3 in mathematical computation, even the ones with a meg of cache.

      Depends. For people looking to deploy a small, very cheap cluster using PowerPC.. iMacs are the way to go. If you want the higher performance and are willing to spend more G4 is the way to. G4s aren't *that* much more expensive, either.

    Has anyone looked inside the iMacs? Not much there except the monitor. You could probably fit 4 of the logic boards into the space of one G4 server.

    Well, this particular cluster is using 100mb ethernet. The reason is that the iMac isn't exactly easy to upgrade with something like gigabit or myrinet. We do work on G4 clusters that use gigabit or myrinet for a very high performance and low latency interconnect fabric.

  16. Power PC built in Clustering Capability with G4 by Anonymous Coward · · Score: 3

    If these guys had just waited until the iMac's come out with G4's, they're job would have been much easier. The G4 contains six new registers separated by semaphores that control locking of memory locations across a network (IP v6 compatible). These aren't available under the Mac OS 9, because it doesn't use the memory protection available from a UNIX-like OS. Mac OS X will support this, hwoever, along with a new release of WebObjects, positioning Apple as a leading e-commerce platform provider with Sun and IBM. Apparently, many users of the Mac OS have been pestering Motorola to add this into hardware. I predict it is unlikely to be in Linux in the next few months. With the current lack of multi-pipeline support in the kernel, it will take several man-months of effort to work this properly. Several architectures have been proposed, I favor a regimented memory access (RMA) style.

  19. G4's are mean scientific machines by Raleel · · Score: 3

    Well, from the experiences I ahve had recently, g4's are mean mean mean scientific machines. We have quite a few floating around the national lab where I work. The PC/MAC team is going head to head with the Unix team on Seti@Home. I was holding the top spot with my dual p3's chewing up chunks. Then in comes these G4's..they are averaging about 5 hours per processor on a block. That's really quite good. Of course, we countered with the PA-RISC machine that could do 24 an hour ;) But the fact of the matter is that their performance is prompting us to look at g4 clusters as a scientific computing solution. Go figure. I wonder if Apple will buy into it..their machines as scientific boxes ;)
