You are right, you should not bite. C code is superflous, this is 
a general issue with efficient parallel computations. You want to 
avoid dependencies within a single register.

E.g. Take a recurrence relation and make an efficient simd 
implementation for it.  You might need to try to expand the terms 
so you have N independent formulas. If it uses floating point you 
will have to be careful about drift between the N formulas that 
are computed in parallel.
