	openMosix, an Open Source Linux Cluster Project
		The openMosix Community makes this a very special project and this is the place where they and their contributions are recognized.
		With openMosix' Auto Discovery, a new node can be added while the cluster is running and the cluster will automatically begin to use the new resources.
		openMosix is licensed under version 2 of the GNU General Public License as published by the Free Software Foundation.

	Documentación Gentoo Linux -- OpenMosix y Clusters en Gentoo
		OpenMosix es un parche al kernel de Linux que permite a varias máquinas actuar como la imagen de un solo sistema (denominado en inglés SSI).
		OpenMosix migra procesos pesados explícitamente cuando está ejecutando binarios a.out o ELF, o cuando un proceso pesado se divide.
		Además un servidor openMosix necesita estar operando, de manera que un nodo pueda unirse a un cluster y hacer uso pleno de las características de openMosix.

		As you may know, clustering technologies allow two or more networked Linux systems (called "nodes") to combine their computing resources to solve computing challenges faster than would be possible if they were tackling the problem on their own.
		Choice of hardware is flexible of course, and openMosix is not limited to any single hardware platform, but clusters built on systems running Intel® Xeon® processors will have some unique advantages.
		By the end of the series, you'll have your own openMosix mini-cluster up and running and will be ready to use it to effectively accelerate your computing tasks.

	the openMosix Stress-Test
		The openMosix stress-test runs several programs to check the functionality of the whole system.
		Simply calculates sin+sqrt from a value 1000000 times and outputs it outputs the loop count to a file (which will grow a lot) This tests is started as many times at once as many processors you have in your openMosix cluster automatically.
		The 'forkit' test is similar to the 'eatmem' test but uses fork to create multiple process (3*[processors_in_your_openMosix_cluster]) expect it does not write to files.

	OpenMosix - Wikipedia, the free encyclopedia
		It allows program processes (not threads) to migrate to machines in the node's network that would be able to run that process faster.
		openMosix is currently considered stable on the x86 architecture.
		openMosix currently works with the Linux 2.4 kernel and the Linux 2.6 kernel (but the userland tools are still under development for the 2.6 kernel).

	Advantages of openMosix on IBM xSeries, Part 1 (Site not responding. Last check: 2007-11-03)
		Because openMosix is completely transparent to all running programs, the process that has been migrated doesn't even know (or need to know) that it's running on a remote system.
		This means that openMosix won't be able to speed up a single process such as Mozilla, except to migrate it to a node where it can execute most efficiently.
		OpenMosix is a fairly recent branch of the original Mosix project, which also provides transparent clustering solution for Linux.

	LinuxDevCenter.com -- Introducing openMosix
		The openMosix project, born in early 2002, is not the first occurrence of this technology.
		One of the differences between openMosix and other clustering environments, such as Beowulf-style clusters, is that for an application to run on an openMosix cluster there is no need for recompilation or integration of other libraries.
		Even though the openMosix project isn't that old, it has grown to be one of the most active open source projects around.

		In contrast, openMosix is an ideal fit for these types of dual-use clusters because the openMosix process migration technology does all the legwork for you.
		Because of this, openMosix allows clusters to be set up in environments where it may not have been practical before.
		OpenMosix realizes that the process should be kept right where it is for maximum performance.

		In order to set up an openMosix cluster, you'll need two or more Linux* systems that are connected on a LAN.
		In order to run openMosix, they should be capable of compiling and running a 2.4 series kernel.
		The faster your network, the more efficiently openMosix will be able to migrate processes between nodes in your cluster.

	openMosix General Instructions (Site not responding. Last check: 2007-11-03)
		Please be kind enough to download the kernel using a mirror near to you and always try and download patches to the latest kernel sources you do have instead of downloading the whole thing.
		At the moment I write this, the latest 2.4 kernel is 2.4.20 so you should download the openMosix-2.4.20-x.gz patch, where the "x" stands for the patch revision (ie: the greater the revision number, the most recent it is).
		Before starting openMosix, there has to be an /etc/openmosix.map configuration file which must be the same on each node.

		Then, we will reboot our nodes and execute the openMosix startup script on each node in our cluster; at this point, openMosix will be enabled and processes will be able to migrate to the nodes where they can execute most efficiently.
		To begin our adventure, go ahead and download the most recent version of the openMosix kernel patch, being sure to note which kernel source tree version to which it should be applied—somewhere on the openMosix main page should indicate which kernel source tree it depends upon.
		The openMosix filesystem is extremely handy for cluster-related tasks, but can also be used to simply copy files back and forth between the various nodes in your cluster.

		This new line will ensure that the openMosix networked filesystem is mounted to the /mfs mount point when our nodes are restarted.
		Now, take the appropriate steps to add the /etc/rc.d/init.d/openmosix script to each node's default runlevel; the openmosix script requires that your network is started firstâ”take that into account when choosing when the script will run.

		Load-balancing is configurable during runtime using the /proc/hpc interface e.g openMosix is using a "speed" variable which is calculated at boot up from the openMosix kernel according to the speed of a Pentium 1Ghz.
		The main openMosix configuration utility is mosctl, with this tool you can define weather processes should stay or leave the current node, you can set a new speed for a certain node, you can ask migrated processes to come home again and much other features that are documented in the howto.
		The openMosix community is a growing and active group of contributors to different parts of the openMosix project.

	LTSP+OpenMosix: A Mini How-To (Site not responding. Last check: 2007-11-03)
		OpenMosix (http://openmosix.sourceforge.net/) is a completely Open Source fork of the MOSIX clustering system.
		OpenMosix, like the original MOSIX, is a clustering system that in the most basic of terms combines the cpu resources of the client systems into what could be compared to an SMP processing system.
		The hope or theory is that since the K12LTSP client is simply executing XWindows and nothing more that OpenMosix can be implemented to utilize the idle processor cycles on these clients to maximize the efficiency of the entire system--relieving some of the stress that the server is under.

		The availability of this online openMosix cluster service will help both new users overcome the initial openMosix configuration issues, and also provides higher computing power to openMosix users who are developing or porting their applications.
		If you download openMosix as a binary package (such as an rpm file), you don't even need to take care about the kernel patch because the kernel has been patched and compiled with the most common default options and modules for you.
		Creating a "Master" node Although openMosix architcture does not require a master node as such, you might want to have a head node from where you launch processes, this might be a multihomed node from where users log in to your cluster.

		Bootable Cluster CD The bootable cluster cd (BCCD) provides a boot-up openMosix clustering solution that is intended primarily for cluster computing education.
		It is now possible to specify how much CPU time a particular node will allow to be consumed by openMosix jobs running on it, so as to control exactly what load that node will accept and to forcibly migrate any jobs that impose too great a load away to other nodes.

	Gentoo Linux Documentation -- Gentoo Linux + Openmosix + LTSP Guide (Site not responding. Last check: 2007-11-03)
		During our earlier trials with openMosix, we found that nodes using Intel Pro/1000 Gigabit NIC's refused to boot with a kernel compiled with GCC 3.2.3, and that this problem was apparently fixed when we switched to a kernel image compiled with the earlier version of GCC.
		Various migration and monitoring tools are available for openMosix, intended to give you a greater degree of control over what processes can be migrated and where they can be migrated to.
		After all, couldn't we have just said, "Shut down openMosix before trying to compile anything, because it won't work?" Well, yes...but we felt this problem deserved its own section for being such a major pain in the butt throughout the three different versions of openMosix we've installed on our cluster.

	Some notes about building a Linux cluster (Site not responding. Last check: 2007-11-03)
		MPI and openmosix play very nicely together, the processes that MPI spawns on remote nodes are migrated by the OpenMosix load balancing algorithm like any other process.
		OpenMosix is a kernel modification that makes a group of computers act like a multiprocessor machine (SMP), so the simplest way to use Neumann is to just ignore it, it will run your CPU intensive jobs on whatever node has spare CPU.
		OpenMosix is designed to allow you to run multiple jobs simultaneously in a simple way.

		Note that openMosix is currently only available for 2.4 series kernels: a 2.6 series openMosix kernel is currently in development but is not ready for production use.
		The openMosix system is simply an extension to the kernel, and will be treated like a standard kernel by your bootloader.
		openMosix can't migrate processes which memory map devices, so executables compiled on these versions cannot migrate (check /proc//cantmove to see if this is the case).
