<b style="font-weight:bold">Explicit Architectural Support for Data Movement and Interprocess Communication</b><br>
<br>
<b style="font-weight:bold">Abstract:</b> <br>
Despite their substantial complexity, current computer architectures are, in several important ways, essentially unchanged from the single-processor, flat-memory, modified Harvard architectures first developed in the late 1960's. Current technology, on the
other hand, has completely different balances than it did 40+ years ago, so that massive investments in processor design are now required to hide the fundamental (and growing) mismatch between what the architectures make visible and what the technology makes
expensive. <br>
In the context of current technology, the most important factors in application performance are often related to control of data motion "vertically" through the memory/cache hierarchy and to efficiently performing communication/synchronization operations "horizontally"
between cooperating parallel processes. These data transfers are expected to dominate the power budget as well as the performance equation in future systems. <br>
Current architectures do not provide the features to manage or optimize these operations. Several examples of performance, power, and/or cost benefits of providing architectural control over data motion and communication/synchronization will be presented and
discussed. <br>

John McCalpin is a Research Scientist in the HPC Group of the Texas Advanced Computing Center. McCalpin began his career in HPC working in large-scale ocean circulation modeling, then spent 12 years in industry, holding leadership positions in the system architecture
and processor performance teams at SGI, IBM, and AMD. McCalpin has been at TACC since 1999, where he focuses on performance analysis, performance tools, and architecture evaluation. <br>
