Mandrake Announces Turn-Key Clustering Distribution 187

Posted by timothy from the clic-and-run dept.
joestar writes "According to their website, Mandrake and partners (Bull, INPG/INRIA...) have launched an 'easy-to-deploy easy-to-use Linux Clustering solution,' that has already been tested on a 40-node cluster. Of course, it's published under the GPL, comes with parallel applications, and is available for download as an ISO. It seems the project is financed by French government. It's great because I've always dreamed of having my own supercomputer at home."

      You've obviously never built a real computational cluster. Real cluster nodes are better off not having any drives at *all*, as they are the only moving part in the mix. It boots PXE, loads a kernel, and nfs mounts root.

        i run a 100 node computational cluster. the nodes boot with pxe, then if they are already installed, they simply boot to their local scsi drives. only /home is mounted via nfs from a disk array, so each individual node has access to the users' programs. we use fast ethernet for that, since it doesn't put that much strain on the network, and myrinet for the computational nodes to exchange data.
        i've had more problems with ram and myrinet than the 'moving parts', aka drives.

      well then use OSCAR from here [sourceforge.net]. It supports mandrake (and redhat) and scsi has the tools listed for CLIC, tested up to 128 nodes, doesn't require PXE card (though I would have to say a network switch is kinda needed for networking :) ). Has a fairly large base and good developer base.
    • The nodes should'nt be installed with SCSI because the duplication program (really fast 1Gb in less than 2min !) doesn't handle it but it seems to be fixed soon. But you can have scsi on the server of the cluster ! But if you wan you can make installation using the normal installation on all node but it will take more time :-)

    Good. I hope this will convince CEOs in large companies that Linux clusters and scales better than Windows (well, that's obvious) or proprietary Unices. But the penguins can't be too confident, as Sun is up to no good here, [com.com] hawking distributed clustering as a brand new technology when it certainly isn't, and catering to Fortune 500s and other large companies.

        Granted, if you are a Solaris fan, you'll be cheering for Sun (maybe...), but you'll still do a double-take at the news that Sun is out to try and "invent" distributed clustering. Read the CNet article carefully:

        Sun Microsystems has come up with a way to insulate computer networks from fires, floods and bomb attacks: Split up the machines and put them in different cities. The Santa Clara, Calif.-based server manufacturer on Tuesday will unveil its Enterprise Continuity program, a collection of services and technology designed to prevent network failure by physically separating computers that work together in a unified cluster.


        CNet may be totally off their rocker (which wouldn't surprise me), but I think it's more likely Sun provided this misinformation, verbatim, in a press kit to CNet. Sun's trying to be the first out the door when they're not; they're offering their service at a premium, saying 'this is the only way you can distribute your data centre'. That's what I call misleading advertisment.

One of the OSC guys has a small(4-5 machines) P2 cluster in his office...its really not extremely difficult...except that I'm using P1's(cause i can get them for far less money). OSC has fairly well automated the install process for anything 686 and above. Using 586's means having to do most things manually. And before someone points it out, yes i'm aware i'm not gonna get a whole lotta power here...i'm doing it as a learning experience, right now noone is going to let me serup a cluster all on my own, so this is the best way for me to learn it i think. Incidentally, one of the things i want to try next is getting GUI desktop-type programs to distribute across my P1 cluster. The idea is to take all of these old systems, and get comparable functionality out of them as you get from your typical desktop computer. I really hare seeing how many systems end up tossed in the trash, i feel like something like this could prove helpful in eliminating some waste. Of course it could also just be a lot of hard work for nothing. Guess i'll find out this summer!

      From the command line, urpmi will give you similar functionality (mainly deal with the dependencies for you). And even nicer, the GUI for Software Management in MandrakeControlCenter is just beautifull. Really painless software management, as long as you install software from the installation CDs or urpmi-aware repositories. Security updates are just a few clicks away and you get to see the advisories and decide what you want to install and what you don't. When installing from CD's you are prompted to insert the CD's in the order they are needed. You can search for packages (in names, files and descriptions). I NEVER had any problems, never had to manually solve dependencies (with ML 9.0). It works like a charm ...

    • In the longer term, set up all the desktops in your orkplace wth this Mandrake distro and use it for storage (Aka freenet) as well as processing, nothing unique to any particular desktop so you can add/delete from the LAN at will.

      So how about combininng all the no-fuss PVM setup stuff with the Gibraltar bootbale Debian CD?

    One could argue that those businesses that really need a cluster will likely buy one preconfigured. Those that do the preconfiguration probably have an established technique (distro, tools, etc.) and won't likely go for something from Mandrake. The hobbiest who builds one to learn about clusters more than likely wants to do everything himself (like start with a strip down install of slackware and build it up from there).

      Right. Netware 6 has kick-ass "clustering" that allows a Server to go down, and a 2nd server to beome your file server. You can stream a video (from FILE), down a server, and after a second, your stream will continue - from the 2nd server.

          To do what? File Serving? SQL Server?

          I believe NFS is 'HA', and I believe Postgres SQL would also be HA. There are also Linux-based load balancers available, so if you wanted to do something as simple as have 2 servers with static web pages, the load balancer would NAT those two systems, and direct requests to whatever one had the lowest load. That includes being completely down too :)

          One nifty HA application is Email. Take a look at Matt Simersons FreeBSD email toaster [simerson.net] (The Same apps are available on Linux) for a way to setup a HA Email cluster. It describes one system, but add NFS and MySQL replication, and you have HA.

    How does it works:
    You create a group of hosts so the server can ask the nodes (using urpmi) to prepare for an update/install of packages.
    Each computer tell the server the packages it needs then the server copy in parallel (using ka-tools) the rpms on the nodes (that's very fast even for a hudge number of nodes).After that, nodes update their system using local rpms !

Why? Every single time that Microsoft, Adobe or some other closed source company is looking for government money, the politicians are facing a rather guestion: "In what light will this put us?"

    Now, it would be interesting to see some years further and see how this all changes. I am convinced that there will much more public discussion on the subject whether this is discrimative against the non-open source companies.

    MS Lackey: Those Mandrake linux people released an ISO image of linux for the XBox, sir, and then they released clustering software. XBox supercomputing clusters are now springing up all over the place.

    Bill: Quickly, we must couteract this. Launch a shared source initiative, and I want the records showing everyone who has puchased an XBOX without buying any games for it!

    MS Lackey: Right away, sir.

    Bill: Oh, and while you're at it, buy France, jail the government, and burn down the Mandrake offices. That'll teach them.
  • I think we should ban marketing speak in the headlines. I get enough emails offering me "exclusive" PDF White Papers from companies talking about "synergy", "best-of-breed", "turn-key" solutions that will help my company "achive success in the competitive and challenging market of today".

    Bah! Such rubbish!

    Anyone agrees with me?

    I think you're all missing the most important question. When are we going to see video games for super clusters?
  • TerraSoft [yellowdoglinux.com] of Yellow Dog Linux fame has offered the same thing for the PPC arch for some time already. The product is called Black Lab Linux and Terrasoft has done quite a few demos with this powerful clustering software, videos and other promotional material are located on the website. The software was also recently tested with a cluster of Apple Xserves

    /me drools...

    And no I don't work in anyway for TerraSoft.

  • I've got machines all over the place, and have long fantasized about setting up a cluster for the fun of it. I've read a little about Beowulf and one or two other open source clustering technologies, but have never had the gumption to crack the books and set one up. Mostly, I think, because I'm not sure what I'd do with it when it was ready.

    Would anyone care to post a 2-3 paragraph summary of what Joe PC Hobbyist (e.g. someone like me, with many semi-obsolete PCs lying around the house) might be able to do with the CLIC software? Would it only be able to run applications written for CLIC (oh.), or would the cluster behave like one giant, amalgamated Mandrake box (cool!) ?

    • Well, I don't know how to use CLIC, but I set up a cluster using some surplus P2s, RH 7.3, and openMosix [openmosix.org].

      For kernel 2.4.18, openMosix consists of two kernel patches - a kernel patch to actually do the clustering, and a kernel patch for administration. You patch your kernel, change a few settings (all documented on the site), reboot (gasp!), and you're done.

      You can get more fancy with net installs, but you don't really need to for a small number of nodes. Anyway, I just used a Fast Ethernet switch - the boxes all came with Ethernet cards, luckily for me.

      Mine is a pretty craptacular cluster, but hey, it's pretty cool to have one. The cluster behaves like one powerful computer in the sense that processes on one machine will migrate to another. However, in order to achieve any noticeable affect, the program has to take advantage of multiple CPUs. If you're going to program your own, look into forking, message-passing interface (MPI), and parallel virtual machine (PVM). Sorry, I don't have the addresses for them on hand, I think www.beowulf.org [beowulf.org] links to them.
  • I've seen a lot of people comment on how much energy this would use, but no real numbers. I know it's subjective as to where you live, but generally, how much energy does a computer use? How much would this use?
  • Now all of those crap boxes that "walked home with me" from last tech job will be put to use. This is remarkable to me, I had no idea that such a project was in the works. A question though, do you think that this little freebie from Mandrake and the French Government will affect the profits of a company like Linux NetworX or the use of Beowulf?

    This seems pretty easy to me. Add the follwing to your RedHat distro, a little scripting, a little autorun info and you got it (for your hardware at least).
    You will need:
    Then:
    1. Install RedHat
    2. Install openMosix rpms
    3. Install kernel source to /usr/src/linux and patch with openMosix-2.4.18-4.gz
    4. Compile and install openMosixUserland-0.2.4
    5. Configure /etc/openmosix.map
    6. Reboot new openMosix kernel
    7. setpe -W -f /etc/openmosix.map
      on each node
    9. ...and you're clusterin'
  • Maybe I'm missing something, but how is this different from MOSIX [mosix.org]?

    I have a small 6-node cluster of P2s running openMosix [openmosix.org]...
  • It's great because I've always dreamed of having my own supercomputer at home."

    So uh, get a playstation 2. Or a G4. Ha ha.

    You know clustering has been around for a god damned long time, and (low end) PCs have been cheap for a less long but still considerable amount of time. You could have built yourself something decent a couple years ago.

    If this is the answer you've been waiting for all this time, I'm not sure I want to know what the question was.


  • Awesome! Just when I was about to declare Red Hat the winner, Mandrake comes up with a "cluster in a can". Great news.
