Concerning qt and optimization, I should insist. I wrote certain qt applications. Certain redraw events in a list window take lots of time (no IO). The delay is impressing concerning raw athena widgets (which I am using alternatively). So I think that optimization can be essential. Michael PS. My last remark is probably not correctly placed on this list: Opposed to C, f77 contains a lot of context information which can be used in order to speed up programs. As far as I know, Fortran optimization belongs to the best investigated issues. Does g77/pg77 use any of these techniques?
