Optimal Tile Size in Icc

Hello, I'm currently using icc version 12.0.4 20110427. I would like to know what is the default tile factor considered by the compiler when performing loop tiling. In the case of gcc (as of gcc 4.6), it is hardcoded as 51 in the params.def. Does icc use any internal heurestics to find the optimal tile size or is it also hardcoded like gcc ?

I haven't seen icc perform a transformation such as the one which is supposed to happen with the loop-strip-mine option of recent gcc. Do you have an example where that is beneficial with a recent Intel CPU? I might expect your time to be spent better keeping your Intel compiler installation as up to date as your gcc.
