%B Communicating Process Architectures 2013
%X This presentation gives an overview of the challenges
   facing
scientific software developers in exploiting current
   and upcoming
massively parallel HPC facilities.  The
   different levels of
parallelism available in the
   architectures will be discussed, together
with their impact
   for software design and what the trend is for the
future. 
   The discussion will be illustrated with examples from the
   two
national facilities currently hosted at EPCC: HECToR (a
   Cray XE6) and
the DiRAC IBM BlueGene/Q.
