thare is no communication between processes
I\m not sure how MOSIX do with shared memory for example.
MPI or PVM will be much faster when used with proper paralization.

MPI works for near all of OS's.
for truth there are some PVM libraries wich used in real MPI.
as I remember that's in AIX port of PVM.
