    摘要: Embodiments of the present invention are directed to implementing high-radix switch topologies on relatively lower-radix physical networks. In one embodiment, the method comprises constructing the physical network (702) composed of one or more optical switches connected via one or more waveguides. A desired switch topology (704) is then designed for implementation on the physical network. The switch topology is then overlain on the switch network by configuring the optical switches and waveguides (706) to implement the switch topology on the physical network. The optical switches can be reconfigured following a transmission over the physical network and can be configured to implement circuit switching or packet switch.

    摘要: A distributed balanced tree having a plurality of nodes distributed across a plurality of servers is accessed. Version information associated with a node of the distributed balanced tree is retrieved. Validity of a lookup transaction performed on the balanced tree is determined by verifying a version value of only the leaf node accessed during the lookup operation against the retrieved version information.

    摘要: Embodiments of the present invention relate to systems and methods for distributing an intentionally skewed optical-clock signal to nodes of a source synchronous computer system. In one system embodiment, a source synchronous system comprises a waveguide, an optical-system clock optically coupled to the waveguide, and a number of nodes optically coupled to the waveguide. The optical-system clock generates and injects a master optical-clock signal into the waveguide. The master optical-clock signal acquiring a skew as it passes between nodes. Each node extracts a portion of the master optical-clock signal and processes optical signals using the portion of the master optical-clock signal having a different skew for the respective extracting node.
