i've seen how MOSIX easily migrates processess, but I have no idea how
delays affect performance ('ve seen it used for number crunching at
physics department, so large startup doesen't affect this environment so
much)

 what other systems allow easy HPC?

pvm/mpi allow number crnuching type of distribution, from distributed OS I
expect mainly load balancing ( I'd be probably better of trying to
properly designing my setup, I am just wondering what do people use
MOSIX-style thingies for )

How is MPI better then MPI ? ( i've used pvm, and my teacher said sth
about MPI being known as better technique ). Is MPI available for
different types of machines? ( with pvm I can make ?cluster? out of 
bunch of PCs in labs and add to it my 2 processor sparc with solaris )
