] | Determine and return the best layout of "tiles" for fastest
overall parallel processing of a rectangular image broken up into N
smaller equally-sized rectangular tiles, given as input the number
of processes/chunks which can be run/worked at the same time (pool_size).
This attempts to return a layout whose total number of tiles is as
close as possible to pool_size, without going over (and thus not
really taking advantage of pooling). Since we can vary the
size of the rectangles, there is not much (any?) benefit to pooling.
Returns a tuple of ( <num tiles in X dir>, <num in Y direction> )
This assumes the image in question is relatively close to square, and
so the returned tuple attempts to give a layout which is as
squarishly-blocked as possible, except in cases where speed would be
sacrificed.
EXAMPLES:
For pool_size of 4, the best result is 2x2.
For pool_size of 6, the best result is 2x3.
For pool_size of 5, a result of 1x5 is better than a result of
2x2 (which would leave one core unused), and 1x5 is also better than
a result of 2x3 (which would require one core to work twice while all
others wait).
For higher, odd pool_size values (say 39), it is deemed best to
sacrifice a few unused cores to satisfy our other constraints, and thus
the result of 6x6 is best (giving 36 tiles and 3 unused cores). | [
