%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.
