Hi,
I'm not sure if anyone has done a tile size test with manta before. I just did one for the default scene, tile sizes 1x1 through 32x32. The minimum fps was 6.65 and the max was 17.0. Bottom left corner is 1x1 and bottom right corner is 32x1. The maximum working tile dimension appears to be 32 in the itanium2 branch..

I wrote a perl script, which I will put in StandAlone/. The script produces a text file which can be transformed into a plot using unu.

bin/manta -np 12 -ui null -imagedisplay null -bench 20 10 -imagetraverser "tiled( -tilesize NxN )"

The default size is 32x2. I think some additional tests will be useful.
