and specifically, openmosix is the open source version of mosix: *openMosix* is a free <http://en.wikipedia.org/wiki/Free_software> cluster<http://en.wikipedia.org/wiki/Computer_cluster>management system that provides single-system image <http://en.wikipedia.org/wiki/Single-system_image> (SSI) capabilities, e.g. automatic work distribution among nodes<http://en.wikipedia.org/wiki/Node>. It allows program processes<http://en.wikipedia.org/wiki/Process_%28computing%29>(not threads <http://en.wikipedia.org/wiki/Thread_%28computer_science%29>) to migrate to machines in the node's network<http://en.wikipedia.org/wiki/Computer_network>that would be able to run that process faster (process migration<http://en.wikipedia.org/w/index.php?title=Process_migration&action=edit>). It is particularly useful for running parallel and intensive input/output<http://en.wikipedia.org/wiki/Input/output>(I/O) applications. It is released as a Linux kernel <http://en.wikipedia.org/wiki/Linux_kernel> patch, but is also available on specialized LiveCDs <http://en.wikipedia.org/wiki/LiveCD> and as a Gentoo Linux <http://en.wikipedia.org/wiki/Gentoo_Linux> kernel choice. However, after doing some research it won't really help in the situation I need it. With apache as the web server. Basically, we require more high-availability and load-balancing than raw processing power. Openmosix provides the raw processing power, but doesn't do much for the other two. In addition, openmosix doesn't work with apache or mysql (or any other shared memory application). There is a patch to attempt to resolve this issue, but as best as I can tell it is in no way ready for production. So, this leaves me still looking for a cluster solution to cluster apache and mysql. Any suggestions? i've been looking over the Linux virtual server project and JBoss clustering (not apache). http://www.linuxvirtualserver.org/ http://www.jboss.org/developers/projects/jboss/clustering any suggestions or experiences are welcome. bb -------------- next part -------------- An HTML attachment was scrubbed...
