You can build virtual bproc clusters. bproc is a much lighter weight system than opemmosix or openssi. We run 12,000 CPUs of cluster here at LANL with bproc. It's very nice. If you are interested I can get you a writeup on how we did this. The work was done about 18 months ago. for more info on bproc, see clustermatic.org. The next-gen bproc we are doing, called xcpu, is even lighter weight than bproc, and runs on any kernel, though for full capability it is good to have kernels >=2.6.14 ron
