When I time my performance for assignment 9, I see a speed up going from P = 1 to P = 4, but as I include more processors, the time taken increases w/ P = 32 being slower than P = 1. Is this to be expected given all the communications between processors? Or is it likely that my implementation for the assignment is just not optimal?

The scaling should flatten out relatively quickly for this problem, that is correct, but you should not see a substantial slowdown as P increases.
