'3' is a common number as well as 'power of 2' in such a common case like

Learn about : Least Common Multiple first then : http://en.wikipedia.org/wiki/Least_common_multiple it'll tile using a 96x96 tile which will -oh snap- fullfill both requirement.
but that is not the programmer's intention indeed!
Tiling is often done with similar values anyway. Like unrolling, this is a expert-user option and should be used with care if you don't know what you are doing.
i would prefer at least one of either tiling (most appropriate) to take place but not that totally different thing
Except the Least Common Multiple do exactly what it should. -- ___________________________________________ Joel Falcou - Assistant Professor PARALL Team - LRI - Universite Paris Sud XI Tel : (+33)1 69 15 66 35
