A massively parallel computer involves a large number of routers that are independent of each other. Adaptive routing methods offer high levels of flexibility in packet routing, but their performance is limited due to their locality nature. The Cross-Line method handles quasi-global information of congestion to improve performance. This paper introduces two new ideas of adaptation level and evaluation...
In the present paper, we use an electromagnetic field simulator across the entire UWB range to perform analytical evaluation of the structural parameters governing the characteristics of omnidirectional UWB notch antennas. As a result, it was found that there are certain dimensions for the slot and positions for the feed point for which the bandwidth is maximized, and the obtained characteristics...
Diffracted waves are widespread in nature. They can be generated by the scattering with disordered and/or ordered system. Topological defects, such as phase dislocations or polarization singularities, can be hidden in complicated field pattern that arises from this multiple scattering. Photonic crystals owe their peculiar optical properties from the interference that emerges from the diffraction of...
With the prevalence of chip multiprocessor (CMP) on server and client computers, it becomes an important issue to use the multicores to speedup existing sequential programs. Decoupled software pipelining (DSWP) is a recent proposed technique that extracts non-speculative threads from sequential programs for higher performance. However, this technique is not effective on commodity CMP architecture,...
