I have five dual CPU SMP boxes networked on a high speed switch. I've done several projects that use this setup as either a load balanced server or a beowulf cluster. While I haven't used Mosix (I use these machines for tests and development, I hesitate to use a heavily modified kernel), I do think it is neat. The reason why I'm curious about NUMA simulation is the idea that it could be possible to run programs written similarly to how you'd write MPI programs, but with "implicit" sharing of memory instead of "explicit" sharing in the form of messages. ccNUMA should be able to be implemented on the x86 architecture using virtual memory mapping and the shm library. It would probably take a kernel module or two, but it would be cool.
