Hi all,
I made the observation that Carpet's output is quite large compared to the grid structure:
on 100^3 gridpoints per refinement level dumping admbase::metric (6 gridfunctions) in 3d hdf5
I would expect for 1 ref-level 10^6*6*8b = 48Mb. I got 80Mb.
I assume that is because Carpet also includes x, y, z, and t in the dump,
which brings it to 10 GF's and 80Mb expected.
But for 2 levels I got 250Mb.
For 3 levels I got 450Mb
and for 4 levels I got 620Mb.
This seems much even if I take ghost- and buffer-zones into account.
Am I missing something, or is Carpet doing something unexpected?
thank you
Michael
