Boids – a log of Learning Java EE 7 / 8

Plan multithreading for the boid calculation

- definition of “one round”
- parallelism explained
- shadow values (a copy of locations before calculation)
- using shadow values the execution (order of picking a boid) from mesh does not matter
- shadow buffer makes the calculations virtually as if they were done in “natural way”: all
*at once* - opposite of using shadow buffer would be calculating the boids updates
**serially**; thus the fresh-in, inter-round position of a boid would be used for all other members’ calculations; thus ordering of calculation would have an effect on the resulting positions (a externally introduced flaw, sort of**order bias**)
