Kerrighed is a single-system image (SSI) cluster software for Linux. It is open source. Amongst many other features, it supports DSM concept with Sequential consistency model, process migration and to limited extend, checkpointing. Kerrighed features novel concept of container. Container may be abstraction of both files, and memory. Single-system image or SSI is a form of distributed computing in which by using a common interface multiple networks, distributed databases or servers appear to the user as one system. ... Linux Cluster at Purdue University. ... Linux (also known as GNU/Linux) is a computer operating system. ... Open source refers to projects that are open to the public and which draw on other projects that are freely available to the general public. ... Distributed Shared Memory (DSM), in computer science, refers to a wide class of software and hardware implementations, in which each node of a cluster has access to a large shared memory in addition to each nodes limited non-shared private memory. ... Sequential consistency is one of the consistency models used in the domain of the parallel programming (e. ... To quote Matt Dillon (of DragonFly BSD), Checkpointing allows you to freeze a copy of an application so that, in theory, you can restore the program to that running state at a later point in time. ...
It was started on October 1998 in the Paris research group at IRISA, under the direction of Christine Morin. 1998 (MCMXCVIII) was a common year starting on Thursday of the Gregorian calendar, and was designated the International Year of the Ocean. ...

The goals of Kerrighed are ease of use, high performance of applications, high availability of the cluster, efficient resources management, and high customizability of the operating system.
Kerrighed is implemented as an extension to the Linux operating system (a set of modules and a patch to the kernel).
Since 2006, Kerrighed is a community project developed by Kerlabs, INRIA, and a growing number of contributors.
Kerrighed system, one of the leading SSI technology for clusters, will be presented.
Kerrighed is a distributed operating system based on Linux giving the illusion of a virtual SMP machine.
She leads Kerrighed research activities aiming at the design and implementation of a single system image cluster operating system for high performance computing (http://www.kerrighed.org).
