[yt-users] covering grids, memory

Hi--

I'm trying to work with come covering grids, extracted at the root grid resolution of a 512^3 sim. I'm on a somewhat memory bound machine (6 gig total).

My data is in double precision, but I'd like to be working in single, as I'm getting memory bound by the things I want to be doing. Is it possible to get the covering grid machinery to force the work to be done in single precision?

Thanks, d.
