openMosix

From Wikipedia, the free encyclopedia
Transfers in an openMosix cluster.

openMosixwas afreeclustermanagement system that providedsingle-system image(SSI) capabilities, e.g. automatic work distribution amongnodes.It allowed programprocesses(notthreads) to migrate to machines in the node'snetworkthat would be able to run that process faster (process migration). It was particularly useful for running parallel applications having low to moderateinput/output(I/O).[1]It was released as aLinux kernelpatch, but was also available on specializedLive CDs.openMosix development has been halted by its developers, but the LinuxPMI project is continuing development of the former openMosix code.

History

[edit]

openMosix was originallyforkedfromMOSIXbyMoshe Baron February 10, 2002 when MOSIX becameproprietary software.

openMosix was considered stable onLinux kernel2.4.x for thex86 architecture,but porting to Linux 2.6 kernel remained in the alpha stage. Support for the 64-bitAMD64architecture only started with the 2.6 version.

On July 15, 2007, Bar announced that the openMOSIX project would reach itsend of lifeon March 1, 2008, due to the decreasing need for single system image (SSI)clustering as low-costmulti-core processorsincrease in availability.[2]

OpenMosix used to be distributed as aGentoo Linuxkernel choice, but it was removed from Gentoo Linux'sPortage treein February 2007.[3]

As of March 1, 2008, openMosix read-only source code is still hosted at SourceForge.[4]The OpenPMIx project is continuing development of the former openMosix code.

ClusterKnoppixis a specializedLinux distributionbased on theKnoppixdistribution, but which uses the openMosix kernel.

Traditionally,clustered computingcould only be achieved by setting up individualrshkeys, creatingNFSshares, editing host files, settingstatic IPs,and applyingkernelpatchesmanually. ClusterKnoppix effectively renders most of this work unnecessary. The distribution contains an autoconfiguration system where new ClusterKnoppix-running computers attached to the network automatically join the cluster.

ClusterKnoppix is a modified Knoppix distro using the OpenMosix kernel.
