If you look up columnar databases, you can find a whole host of research on how these things store data. Storing values column by column to do vector processing is pretty common, but I can't recall seeing one built for a GPU before. Kudos to the dev for diving in to implementing one, it's pretty neat stuff.

Try finding research papers about MonetDB, Vertica/C-Store, or Vectorwise for some background. Or follow the links here:
