			<description><![CDATA[The following extract from the article is of particular interest. Perhaps these software engineering challenges can be tackled via an open source philosophy leveraging the efforts of volunteers! "The authors note that a cross-cutting issue that will impact the entire range of computational efforts over the lifetime of CASL is the dramatic shift occurring in computer architectures, with rapid increases in the number of cores in CPUs and increasing use of specialized processing units (such as GPUs) as computational accelerators. As a result, applications must be designed for multiple levels of memory hierarchy and massive thread parallelism."]]></description>
