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)
