    Ok, I understand.
    Yes, I'm build in 32 bits.

    make -C /usr/src/kerrighed-2.4.1/_kernel O=/usr/src/kerrighed-2.4.1/kernel kernel-install
    make[2]: *** No rule to make target `kernel-install'. Stop.
    make[1]: *** [kernel-install] Error 2
    make: *** [kernel-install] Error 2


    if anyone has answer please let me know... I'm stuck here.

    Best regards.
    Hi Erwanenharma,
    I think i got the same error so i used kerrighed svn. It is listed in post #109 of this thread. After that everything went fine.

    I hope it helps.

    Re: Easy Ubuntu Clustering

    Hello,all.

    I have cluster with 3 nodes in Intel Xeon CPU 2.40GHz.
    In /proc/cpuinfo i see 12 cpu, but if i run linpack banchmarks test, work only 4 cpu.
    Why? Or all cpus can work only with mpi?

    Legacy scheduler behaviour is running.
    And sheduler i configure:
    # krgcapset -d +CAN_MIGRATE
    # krgcapset -k $$ -d +CAN_MIGRATE

    Me intrested run virtualisation(virtualbox, vmware or other who can work) in my cluster. Can I do it with Kerrighed? And,can work virtualisation with all cpu in cluster?

    Thanks

    Note that the two lines above are equivalent, and will only do what you want if you launch the benchmark from the same shell.

    No known virtualization technology (VMware, Xen, VirtualBox, Qemu, KVM, Linux vservers, Linux containers) can benefit from Kerrighed right now. The most promising one is currently Linux containers (which should supersede Linux vservers some day). Qemu, and maybe later KVM could benefit from Kerrighed's migration in some future, but not from resource aggregation (especially CPUs).

    Thanks,

    Louis

    Sorry, don't understand. Where I need launch benchmark?
    I'm login in first kerrighed node and launch benchmark there.

    Re: Easy Ubuntu Clustering

    Hi gys....
    I had set up a kerrighed cluster as a project for my college. Can anyone list some applications in which thread migration or process migration is shown in graphical or textual form.

    Hello, D3ATH-D3AL3R.

    There was a graphical tool to show migration in openMosix:

    http://www.openmosixview.com/

    However this, like openMosix itself, is now unsupported...

    I've been thinking about porting "mosmon" from openMosix to Kerrighed, but I've not done it yet. Might be nice if someone ports openMosix view

    Bye,

    Tony.

    Hello, Louis.

    AFAIK Ubuntu works the same way as Debian, but I find it a lot easier to build the NIC driver into the kernel and PXE-boot without an initrd

    Perceus

    I'm going to try booting nodes on our Kerrighed Beowulf using Perceus:

    http://www.perceus.org

    I mentioned Perceus some time ago on this thread - has anyone succeeded in setting up Perceus for node provisioning in a Kerrighed Beowulf cluster?

    At present, I'm using a home-brew system based on UNFS3 with 'clusterNFS' extensions enabled. Interestingly, Oracle use similar 'context' dependent symbolic links in OCFS (Oracle Cluster File System):

    http://www.dba-oracle.com/real_appli...grid/cdsl.html

    Although OCFS was designed to support Oracle databases, they have recently added POSIX compatibility to OCFS so it can be used as a general purpose filesystem. Perceus does things quite differently...

    Bye,

    Tony.
