| **Thank you!** That's better than drawing ''Walls'' by hand. The right side is the resized MFM simulator by {2C2}. And isn't the smaller simulator running faster? | **Thank you!** That's better than drawing ''Walls'' by hand. The right side is the resized MFM simulator by {2C2}.

| **A: 31-May-2015 01:06:01AM-0600: ** It depends somewhat on your hardware -- in particular, how many //real// cores you have, but yes, in general a smaller grid geometry -- fewer and smaller tiles, down to some limit -- will typically be faster than more and larger tiles. Any single tile geometry will be running single-threaded, though, so in some cases multiple smaller tiles will be faster than one bigger one -- you'll need to experiment some, if maximizing AER is crucial. Also, if you type **''a''** a few times after typing **''i''** in the simulator, it will display the AER it is producing, so you can get a rough sense of what's faster and slower. | **A: 31-May-2015 01:06:01AM-0600: ** It depends somewhat on your hardware -- in particular, how many //real// cores you have, but yes, in general a smaller grid geometry -- fewer and smaller tiles, down to some limit -- will typically be faster than more and larger tiles.

| On a separate point, note that the "edge of the grid" is somewhat different that a ring of ''Wall''s. For example, non-existent sites return ''false'' from the ''EventWindow isLive'' method, but sites containing ''Wall''s return true. For consistency you might want to draw a ring of ''Wall'' around the boundary of even a smaller grid. | On a separate point, note that the "edge of the grid" is somewhat different that a ring of ''Wall''s.
