      Philip, Sujin; Summa, Brian; Bremer, Peer-Timo; Pascucci, Valerio (The Eurographics Association, 2011)
      Gradient domain processing remains a particularly computationally expensive technique even for relatively small images. When images become massive in size, giga or terapixel, these problems become particularly troublesome ...

      Whitlock, Brad; Favre, Jean M.; Meredith, Jeremy S. (The Eurographics Association, 2011)
      There is a widening gap between compute performance and the ability to store computation results. Complex scientific codes are the most affected since they must save massive files containing meshes and fields for offline ...
