openMosix Community Contributions

This is a collection of the Add-On Applications, HowTo Pages, Documents, Code Snippets, and other contributions from the openMosix Community.  These may be packaged tools for installation or use, GUI interfaces, special patches or work-a-rounds, or perhaps just a helpful explanation.  

Matthias Rechenburg openMosixview is an openMosix-cluster management GUI.  The openMosixview suite contains useful applications for monitoring and administrating an openMosix cluster.  fmII
Olexander Sudakov and Eugeniy Meshcheryakov  -  CHeckPOinting for linuX
CHeckPOinting for linuX, CHPOX, provides Checkpointing for openMosix.  CHPOX is SMP safe, works as kernel module, and needs no patch, recompilation, or relinking.  It transparently dumps the state of specified process (or process group) into a disk file. The processes may be restarted from that file at the point they were dumped. For now it supports: virtual memory, CPU & FPU registers, regular files, terminal state, current directory, pipes, Unix sockets, and multiple non-interacting processes.  fmII
Enrico Mastrostefano  -  The Hydra Project integrates automatic CHPOX into a simple script based queuing system.
Enrico has documented and shared his scripts for building and maintaining an openMosix cluster that uses many of our openMosix Community's contributions.  Hydra adds a simple queuing script to manage process submission and provide automatic CHeckPOinting for linuX.  Hydra even takes a Checkpoint as the UPS shuts down the cluster during a power failure.
Matthias Rechenburg  - The chpox - Checkpointing Utility and How to Use It
Matt's Review and How To (with examples) for Olexander Sudakov and Eugeniy Meshcheryakov's  CHPOX, CHeckPOinting for linuX.
Ian Latter  -  Instant openMosix                        How to build a working openMosix cluster without touching a compiler
provides a basic, step-by-step process for installing a working openMosix cluster, using only an off-the-shelf Linux distribution [Fedora Core 1 (Yarrow)] and two 2.4.26 openMosix RPMs. Includes numerous screenshots, hints for resolving openMosix config issues and network config issues.
gomd Project Team - general openMosix daemon
gomd is a daemon which executes commands and gathers information from the nodes of an openMosix cluster.  This is a complete C/C++ rewrite (plus extension) of the Java openMosixInfoServer daemon from Gian Paolo Ghilardi's openMosixApplet. The gomd library will support C/C++ and Java monitoring applications such as openMosixView, openMosixApplet, openMosixWebView, and 3dmosmon. The gomd Team includes Johnny Cache, Mirko Caserta, Massimo Fierro, Gian Paolo Ghilardi, Ramon Pons Vivanco, Brian Pontz, Roel Baardman, Michael Imhof, Wim Vandersmissen, Marco Marocco, Higor Alves, and Matthias Rechenburg.  The project is still seeking additional core developers, contrib developers (to provide interfaces/classes interacting with gomd in any language), and beta testers. The project is mainly targeted at those who develop monitoring software for openMosix clusters, but super-users will find use for the programming API as well.  Binary and source packages for Mandrake, Redhat, SuSE and Debian.  Also there is an ebuild for Gentoo available.

Matthias Rechenburg  -  openMosix API
No, you need not change your programs to use openMosix.  But, this documentation about the openMosix API (Application Programming Interface) will explain in detail what you need to know to create your own openMosix applications such as Matt's openMosixview.  Examples are provided in several "common-languages" (shell, perl, php, c/c++).  You will find functions which you can use directly in your code.  It will also enhance your knowledge about your cluster and help you with administration.

Dirk Westfal - grendelsbane Live Linux CD
A Dragon Slaying openMosix Live CD-based Distribution based upon RedHat that creates an instant openMosix cluster (or adds an openMosix node). It is a Knoppix' like universal "run-from-CD" Linux distribution, but this can boot and run openMosix from the CD.  And now comes Basilisk, a monster GUI (X/KDE Workstation) node with a HISS.
Ian Latter  -  CHAOS is a supercomputer for your wallet.
CHAOS is a CD-based Linux and openMosix cluster distribution.  The CHAOS distribution fits on a single business card sized CD-ROM.  This tiny disc will boot any i586 class PC (that supports CD booting), into a working openMosix node, without disturbing (or even touching) the contents of any local hard disk. Ideal for large-scale ad hoc clusters, once booted, CHAOS runs from memory allowing the CD to be used on the next node (and allowing for automated rebooting into the host OS).  CHAOS aims to be the most compact, secure and straight-forward openMosix cluster platform available.
Ian Latter  -  White Paper - Security and openMosix
Securely deploying openMosix over an untrusted networking infrastructure using IPSEC (Network Level Encryption and Authentication).  This includes the background information for the alternate openMosix node autodiscovery (tyd) available for using CHAOS with ClusterKnoppix.   Or in Ian's words, "This white paper explores the openMosix network architecture, network level risk mitigation techniques for the redeployment of organizational infrastructure in 'open' clusters, a practical application of those techniques in the CHAOS and ClusterKnoppix Linux distributions, and proposals for extending both the security model and the flexibility of the openMosix architecture."

Ian Latter  -  HowTo Run ClusterKnoppix or Quantian with CHAOS
In Ian's words, "HowTo: Heterogeneous Clusters: Running ClusterKnoppix as a Master Node to a CHAOS Drone Army".  Boot a ClusterKnoppix (or Quantian) "master node" from CD and then boot CHAOS "drone nodes" from CD.  It take less than a minute to securely add another CHAOS "drone node" using unicast for autodiscovery (you key in the IP of the "master node" or an already connected "drone node"),  packet filtering and IPSEC tunnels for "no user intervention required" security.
Wim Vandersmissen - ClusterKnoppix

Cristiano De Michele  -  openMosix LoadCpuLimit HowTo
How To use openMosix' ability to restrict the load imposed by the various processes running on an openMosix cluster. Through the use of the various parameters relating to LOADLIMIT, it is possible to prevent a node from being overwhelmed by jobs running on it. 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.
Mikko Huhtala  -  Simple Job Queuing
A sample script in Python implements a simple job queue. The commands to be executed are stored in a list ('queue') and the nodes on which to run them in a second list ('nodes'). The script executes the jobs one after another locked to the nodes listed, waiting for the previous job to finish before starting a new one. Long jobs could be queued so that they are started on the home node and allowed to migrate instead.
Jozef Ivanecky  -  runaway.sh
Launch a task on any remote node but not home node.  Similar to runon but it checks all running nodes and then automatically creates a correct list for mosrun -j option, including all nodes in state 3 but not home node.  Since using this script everything (high IO task on LTSP) is running better - no problem with flooding home node - and also much faster.
