   OpenMOSIX was all about process migration between different 
independent OSes.  You can still get some of that with Scyld, with 
OpenSSI, and a few others.

   If you prefer more of an SMP model (simpler programming), you should 
look at ScaleMP DSMs.  Some on this list argue the shared memory 
programming is not easier than distributed memory programming, though I 
am not one of them who makes this argument.  It has different 
challenges, costs and benefits than MPI.  It has different limitations. 
  Not so surprisingly, with the advent of many-core units, shared memory 
programming techniques are needed to get good performance within a 
single system.

   Disclosure: We are looking at these units for some of our work.
