Stephen, Basically the idea is to combine the processing power of all the idle CPU cycles on the client terminals (since all they are doing is running Xwindows or a shell if you set them to boot at runlevel 3) with the server. Kind of similar to having a really big multi-processor SMP box ;-)
In an LTSP environment where the clients use Xwindows there is concern about openMosix adding overhead on the network bandwidth (and slowing things down) as the processes from the server migrate to the various clients. (Something to watch out for.) So this concept may or may not prove useful *depenging on your circumstances*. But, hey, it's a really fast and easy way to build a clustered system. ("Try doing *that* with windows!" as I like to say...) In the past builiding a clustered system has been more difficult, and I daresay that until openMosix came along I doubt there were too many home clusters out there for the hobbyist. openMosix combined with LTSP really "opens" up a whole new world for administrators and/or hobbyists... In my How-To I follow Mr. Camp's startup for the clients in that it keeps the client processes from migrating (so you don't have client A running Xwindows for client B--that wouldn't be a good thing). The server (where all the action happens) is allowed to migrate processes to the clients as needed (determined by the openMosix alogrithm). "Fork and forget", as the saying goes. It's all done automatically. This is a "good thing", because in other clustering systems you would need to recompile applications to take advantage of the system. Not so with openMosix... Well, I hope I got it right and haven't misstated anything. Thanks for the interest, I hope you find it useful, James Jensen <><><><><><><> openmosix.sourceforge.net live free() or die() --- Stephen Liu <[EMAIL PROTECTED]> wrote: > Hi James, > > openMosix is quite new to me.
