-We can combine these two masks by using a simple logical `ÒR`, i.e. we mask out if condition `CAUSAL` or condition `PACKING` demands a mask out.

 One more important point is the possibility of parallelizing to leverage multiple chips.
 In case of attention it turns out that parallelizing is not difficult to reason about.

 1) We have `BATCH` dimension. Each batch is processed idepently, so we can always parallelize along this dimension.
 2) We have `HEADS` dimension. By definition each head is independent from the other heads so we can parallelize as well.
