	Mosix Configuration
		Once Mosix is installed, the key file defining the extent of the cluster for machines in the cluster is /etc/mosix.map.
		The man page for Mosix states that the method for controlling the behavior of the Mosix environment on any given machine is to write values of either 0 or 1, for off and on, to a series of files in the /proc/mosix/admin directory.
		As you can see, these flags control whether the machine is a mosix node, whether processes are allowed to migrate to other machines, whether processes are allowed to migrate from other machines to the subject machine, and whether the MFS file system is enabled.

	MOSIX - Wikipedia, the free encyclopedia
		MOSIX is a cluster management system that provides single-system image (SSI) capabilities, e.g automatic work distribution among nodes.
		The core of MOSIX are adaptive algorithms that monitor and respond to cluster-wide resource requirements (of all the processes) by automatic migration of processes to the best available nodes.
		MOPI enhances the computing capabilities of Mosix with the ability to support massive parallel I/O. It is targeted at applications that need to process vast amounts of data, ranging from few GByte/s to Terabyte/s.

	MOSIX Computing Clusters
		MOSIX is generic: it provides applications with a run-time environment that is identical to the underlying operating system (currently Linux), so there is no need to change or even link applications with any special library.
		The main goal of MOSIX is to allow owners of nodes to share their computational resources from time to time, while still preserving the autonomy over their own clusters and their ability to disconnect their nodes from the grid at any time without disrupting already running programs.
		MOSIX is most suitable for running compute intensive applications with low to moderate amount of I/O. Tests of MOSIX show that the performance of several such applications over a 1Gb/s campus grid is nearly identical to that of a single cluster.

		The core of the MOSIX technology are adaptive resource sharing (load-balancing and memory ushering) algorithms and a preemptive process migration mechanism, that allow a cluster of workstations and servers (nodes) to work cooperatively as if part of a single system.
		Mosix for Linux was specifically designed for a cluster of computing nodes of the same family (at this stage, only the Intel-x86 family is supported, but the plans are to support other platforms).
		MOSIX measures the processor's speed at boot-time, relative to a Pentium-2 at 400 MHz representing 10000 units of speed.

	MOSIX: A Cluster Load-Balancing Solution for Linux \| Linux Journal
		MOSIX is a software package for Linux that transforms independent Linux machines into a cluster that works like a single system and performs load balancing for a particular process across the nodes of the cluster.
		MOSIX's algorithms are designed to respond to variations in the resource usage among the nodes by migrating processes from one node to another, pre-emptively and transparently, for load balancing and to prevent memory exhaustion at any node.
		MOSIX operates transparently to the applications and allows the execution of sequential and parallel applications without regard for where the processes are running or what other cluster users are doing.

	MOSIX
		MOSIX is a management system targeted for high performance computing on Linux clusters and organizational grids.
		MOSIX provides a single-system image, so that there is no need to modify or link applications with any library, copy files or login to remote nodes, or even assign processes to different nodes - it is all done automatically.
		The latest version of MOSIX for Linux-2.6 supports dynamic configurations, ranging from partitioning of a cluster among several users to an organizational grid with private and shared clusters, like our organizational grid:

	Using MOSIX \| Linux Magazine
		MOSIX is a set of kernel patches and user programs (for Linux and other UNIX variants) that perform automatic and transparent process migration for clustered and even non-clustered computers.
		MOSIX considers both the speed of the processor and the current load on the machine when deciding how to migrate processes.
		MOSIX's Direct File-System Access (DFSA) attempts to solve this problem by allowing remote processes to save time by performing most of their I/O and file system operations directly on the node where the process is currently running instead of having to "phone home." At present, DFSA works only with MFS file systems.

		MOSIX is preemptive, monitoring all the processes, and if necessary, it migrates processes among nodes to maximize overall performance.
		MOSIX algorithms are decentralized, with each node acting both as a master for processes that were created locally, and as a server for (remote) processes that were migrated from other nodes.

	Re: Mosix and traditional Beowulf software together (was Re: Mosix bundle)
		Mosix decided that the P90's povray would run faster on the other P233 (I hadn't tied down the processes)...and it sure did.
		So, far I haven't seen MOSIX try to pick up and move any of my pvmds or any of the processes spawned by pmvpov, but I think that I have the loading balanced reasonably well in my configuration.
		I haven't added MOSIX to my dual P400 that can participate in the cluster yet, but it would be interesting to see if any migration occurs with pvmpov if this box is available.

		Mosix takes heavy CPU processes and migrates them to other, free processors.
		One caveat about Mosix is that all the input/output for a process is done on the master node - this is not a drawback if the ration of compute time to I/O is high, but again you have to look at your job mix.

	Some notes about building a Linux cluster
		MOSIX is a software package that was specifically designed to enhance the Linux kernel with cluster computing capabilities.
		The core of MOSIX are adaptive (on-line) load-balancing, memory ushering and file I/O optimization algorithms that respond to variations in the use of the cluster resources, e.g., uneven load distribution or excessive disk swapping due to lack of free memory in one of the nodes.
		In such cases, MOSIX initiates process migration from one node to another, to balance the load, or to move a process to a node that has sufficient free memory or to reduce the number of remote file I/O operations.

	[Beowulf] Mosix
		Steve, his original question was why we still bother with mpi and other parallel programming headaches when instead we could just use Mosix that does things transparently.
		My response intended to clarify that you still need parallell programming techniques, and your point that you could then also use mosix to have them migrate around (and away from the ressources in the worst case) transparently is true.
		Mosix is used regularly to do image processing and >other highly parallel tasks.

		The resource providers are offering clusters of nodes with processing power (CPU) and memory to MOSIX for the solution of computational problems (jobs), either their own jobs or jobs by third parties.
		Each MOSIX user might thus possess a “prepaid” account in the MOSIX system from which the execution of jobs is paid and which can be “recharged” in case new funding is available.
		Neither resource requesters nor resource providers do have any time constraint, that is requesters submit jobs to MOSIX that can be executed at any time in the future and providers in turn offer their resources 24x7.
