OpenMosix

OpenMosix

openMosix was a free cluster management system that provides single-system image (SSI) capabilities, e.g. automatic work distribution among nodes. It allows program processes (not threads) to migrate to machines in the node's network that would be able to run that process faster (process migration). It is particularly useful for running parallel and intensive input/output (I/O) applications. It was released as a Linux kernel patch, but was also available on specialized Live CDs.Currently, OpenMosix development has been halted by its developers.

History

openMosix was originally forked from MOSIX by Moshe Bar on February 10, 2002 when MOSIX became proprietary software.

openMosix is considered stable on Linux kernel 2.4.x for the x86 architecture, and porting to Linux 2.6 kernel remains in the alpha stage. Support for the 64-bit AMD64 architecture only starts with the 2.6 version.

On July 15, 2007, Bar announced that the openMOSIX project will reach its end of life on March 1, 2008, due to the decreasing need for SSI clustering as low-cost multi-core processors increase in availability. [ cite web

OpenMosix used to be distributed as a Gentoo Linux kernel choice, but it was removed from Gentoo Linux's "Portage tree" in February 2007.cite news |first=Chris |last=Gianelloni |coauthors= Mark Kowarsky, Donnie Berkholz, Daniel Black, Diego Pettenò, Kieth Gable |title=Gentoo package moves |date=2007-02-19 |publisher= Gentoo Foundation, Inc. |url= http://www.gentoo.org/news/en/gwn/20070219-newsletter.xml#doc_chap6 |work= Gentoo Weekly Newsletter |pages= |accessdate= 2007-10-12 |language= ]

As of March 1, 2008, openMosix read-only source code is still hosted at SourceForge. [cite web | url = http://openmosix.sourceforge.net/ | title = the openMosix Project | date = 2008-03-01 | accessdate = 2008-03-01] The LinuxPMI project is continuing development of the former openMosix code.
