Installing openMosix ``the Debian way'' can be easily done as described below.
The first step consists in downloading the packages from the net. I had to use a 2.4.19 kernel since the openMosix patches package is not yet available for 2.4.20 at the moment I write this. Since we are using a Debian setup we needed: .:: telegra.ph ::. .:: telegra.ph ::. http://packages.debian.org/unstable/net/openmosix.html, http://packages.debian.org/unstable/net/kernel-patch-openmosix.html, http://packages.debian.org/unstable/misc/kernel-package.html [r/Machinelearning Topics] , http://packages.debian.org/unstable/devel/kernel-source-2.4.19.html. You can also apt-get install them ;).
The next part is making the kernel openMosix capable.
Basically, the procedure to follow is:
cd /usr/src
apt-get install kernel-source-2.4.19 kernel-package \
openmosix kernel-patch-openmosix
tar vxjf kernel-source-2.4.19.tar.bz2
ln -s /usr/src/kernel-source-2.4.19 /usr/src/linux
cd /usr/src/linux
../kernel-patches/i386/apply/openmosix
make menuconfig
make-kpkg kernel_image modules_image
cd ..
dpkg -i kernel-image-*-openmosix-*.deb |
After rebooting with this kernel and a configured /etc/openmosix.map, you should then have a cluster of openMosix machines that talk to each-other and that do migration of processes.
You can test that by running the following small script:
awk 'BEGIN {for(i=0;i<10000;i++)for(j=0;j<10000;j++);}' |
We also setup openMosixView on the Debian machine:
apt-get install openmosixview |
openMosixView gives you a nice interface that shows the load of different machines and gives you the possibility to migrate processes manually.
A detailed discussion of openMosixView can be found elsewhere in this document.
