- Kerrighed
refimprove date March 2012 Kerrighed is an open source single system image SSI Computer cluster cluster software project. The project started in October 1998 at the Paris research group Institut National de Recherche en Informatique et en Automatique The French National Institute for Research in Computer Science and Control . Since 2006, the project is mainly developed by the Kerlabs company. Background Kerrighed is implemented as an extension to the Linux operating system. It helps scientific applications such as numerical simulations to use more power. Such applications may be using OpenMP , Message Passing Interface , and or a POSIX Threads Posix multithreaded programming model. ref Morin, Christine. http lists.osdl.org pipermail clusters sig 2005 February 000028.html Kerrighed Linux based SSI for clusters ref Kerrighed provides several features such as a distributed shared memory with a sequential consistency model, processes migration from one cluster node to another, and to a limited extent checkpointing . Kerrighed introduces a container concept this entity is an abstraction of both files and memory.

- LinuxPMI
Image OpenMosix.svg thumb right 300px Transfers in an openMosix cluster. OpenMosix is the predecessor of LinuxPMI. LinuxPMI Linux Process Migration Infrastructure is a Linux Kernel extension for multi system image in contrast to a single system image clustering. The project is a continuation of the abandoned openMosix clustering project. Function How LinuxPMI works is perhaps best described by an example. You may have a network of ten computers nodes and there is one user working on each node. Nine users are working on simple tasks that do not necessarily use their machine to the full potential. One user is working on a program that spawns a lot of jobs that would overload his computer. Since we have nine nodes on the network that have a lot of free resources, they can basically take over some of the jobs from the one computer that would otherwise be overloaded. In other words, LinuxPMI will migrate jobs from busy computers to computers that are able to perform the same task faster. Even if all ten users were using their machines for heavy tasks, it could be that not all machines are fully occupied at the same time, and LinuxPMI will use these to reduce the load on other machines. This is in many ways similar in principle to how a multiuser operating system manages workload on a multicpu system however, LinuxPMI can have machines nodes with several CPUs. You can also add or remove nodes on a running cluster thus expanding or reducing the total computing power of the system. In short it means that ten computers are able to work as one large computer however, there is no master machine, so each machine can be used as an individual workstation.
