Abstract
This position paper makes two separate, only tangentially related
points: 1. A research program is necessary to produce tools and
techniques that allow application developers to develop and tune
applications for future exascale machines, well before the machines
are deployed. 2. In order to cope with, or facilitate, segmentation
of exascale architectures, it is necessary to carry out an
extensive study characterizing the needs and behaviors of
applications that are expected to run on exascale machines. To read
