About Tile Decomposition

#1 Unread post by teeth »

Hi, I ask someone to answer me about domain tilling.

Do we have a minimum value of chunksize?

If we have,let me know what the number is.. plz

PS) I have error message as follows: :cry:

============================================================ error message
Tile partition information for Grid 01: 0229x0146x0041 tiling: 024x024

tile Istr Iend Jstr Jend Npts

0 1 5 1 -4 -820

INP_PAR - domain decomposition error in input script file for grid: 1

The domain partition parameter, NtileJ = 24
is incompatible with grid size, Mm = 146
because it yields too small tile, Jstr = 1 Jend = -4
Decrease partition parameter: NtileJ

But why do you want to run such a small application 229x146x40 in 576 (24x24) processors?

Think about it...
