1 A particular way of using MIMD machines - DOMINANT successful use so far.
2 Each processor runs same program but in general executes different instructions at different times.
3 Will later see corresponds to "loosely synchronous problems".
4 Style of current program example -- note although each doing roughly same thing -- i.e. updating grid points -- each node is NOT at same point in update at each clock cycle
