You can download the latest versions of openMosix from http://sourceforge.net/project/showfiles.php?group_id=46729. You can either choose the binary (even in rpm) compiled for UP or SMP or download the source code. You will need both the kernel patch or binaries and the userland tools. Alternatively you can get the CVS version:
cvs -d:pserver:anonymous@cvs.openmosix.sourceforge.net:/cvsroot/openmosix login cvs -z3 -d:pserver:anonymous@cvs.openmosix.sourceforge.net:/cvsroot/openmosix co linux-openmosix cvs -z3 -d:pserver:anonymous@cvs.openmosix.sourceforge.net:/cvsroot/openmosix co userspace-tools |
