A methodology for accurately modeling large applications explores the performance of ultrascale systems at different stages in their life cycle, from early design through production use.
A study of two applications programmed using three models of varying complexity reveals that implicit management of locality can produce code with performance comparable to code generated from explicit management of locality.
The Cetus tool provides an infrastructure for research on multicore compiler optimizations that emphasizes automatic parallelization. The compiler infrastructure, which targets C programs, supports source-to-source transformations, is user-oriented and easy to handle, and provides the most important parallelization passes as well as the underlying enabling techniques.
Parsing is an expensive operation that can degrade XML processing performance. A survey of four representative XML parsing models-DOM, SAX, StAX, and VTD-reveals their suitability for different types of applications.
A service-oriented architecture (SOA) is an ideal vehicle for achieving reconfigurable systems that can select and compose services statically or dynamically to satisfy changing system requirements. The authors have developed a rule-based parameterization technique to convert components into reconfigurable services.
The ISP (instruction Set Processor) notation was developed1 to precisely describe the programming level of a computer. The behavior of a processor is determined by the nature and sequence of its operations. This sequence is given by a set of bits in primary memory (a program) and a set of interpretation rules (usually in the central processor). Thus, if we specify the nature of the operations and...
