All optical fast distributed arbitration in a computer system device

Abstract

Various embodiments of the present invention are directed to systems and methods for all optical distributed arbitration for computer system components (1801-1804) communicatively coupled via a photonic interconnect in a computer system device. The embodiments of the optical arbitration in the computer system provides arbitration schemes with fixed priority (2000) and non-fixed priority (1830, 2200). The non-fixed priority scheme embodiments can provide fairness in arbitration. In some embodiments, delivery of light power and arbitration are combined (1830, 2001).

Description

technical field [0001] Embodiments of the invention relate to resource arbitration in computer system devices, and more particularly to optical channel arbitration in photonic interconnects that provide communication between computer system components in computer system devices. Background technique [0002] In the mid-1960's, semiconductor manufacturers observed that the density of circuits (such as transistors) fabricated on integrated circuits doubled approximately every 18 months. This trend has continued and is now known as "Moore's Law". Transistor density is viewed as a rough measure of computer processing power, which in turn corresponds to data processing speed. Although originally derived as an observation, Moore's Law has over time become widely accepted by the semiconductor industry as the fundamental driving force behind increased computer processing power. As a result, semiconductor manufacturers have developed techniques for reducing the size of chip compone...

Problems solved by technology

The best possible solution can be calculated in O(N2.5) time by an offline sequential algorithm, that is, the Hopcroft-Karp algorithm is calculated for the maximum matching in the bipartite graph, but this is not suitable for use as a crossbar arbitration scheme will be too slow
