Publication number: 20070260821Abstract: In one embodiment, a memory controller for a node in a multi-node computer system comprises logic and a control unit. The logic is configured to determine if an address corresponding to a request received by the memory controller on an intranode interconnect is a remote address or a local address. A first portion of the memory in the node is allocated to store copies of remote data and a remaining portion stores local data. The control unit is configured to write writeback data to a location in the first portion. The writeback data corresponds to a writeback request from the intranode interconnect that has an associated remote address detected by the logic.

Publication number: 20070260614Abstract: A lock-free implementation of an ordered data structure allows updating of the data structure without disturbing the ordering relied upon for accessing the data structure. After searching and finding an element in a data structure in accordance with an update operation (i.e., an insert operation or a remove operation), values are successively copied to shift the values either up or down the data structure. If an insert operation is being performed, then the new value is eventually inserted to overwrite a duplicate value in the data structure. If a delete operation is being performed, then a value is shifted over the value to be deleted.Type: ApplicationFiled: May 2, 2006Publication date: November 8, 2007Applicant: Sun Microsystems, Inc.Inventor: Tim Bray

Publication number: 20070258675Abstract: When using micro-resonant structures, it is possible to use the same source of charged particles to cause multiple resonant structures to emit electromagnetic radiation. This reduces the number of sources that are required for multi-element configurations, such as displays with plural rows (or columns) of pixels. In one such embodiment, at least one deflector is placed in between first and second resonant structures. After the beam passes by at least a portion of the first resonant structure, it is directed to a path such that it can be directed towards the second resonant structure. The amount of deflection needed to direct the beam toward the second resonant structure is based on the amount of deflection, if any, that the beam underwent as it passed by the first resonant structure. This process can be repeated in series as necessary to produce a set of resonant structures in series.Type: ApplicationFiled: May 5, 2006Publication date: November 8, 2007Applicant: Virgin Islands Microsystems, Inc.Inventors: Jonathan Gorrell, Mark Davidson, Henry Davis

Publication number: 20070257208Abstract: An electronic transmitter or receiver employing electromagnetic radiation as a coded signal carrier is described. In the transmitter, the electromagnetic radiation is emitted from ultra-small resonant structures when an electron beam passes proximate the structures. In the receiver, the electron beam passes near ultra-small resonant structures and is altered in path or velocity by the effect of the electromagnetic radiation on structures. The electron beam is accelerated to an appropriate current density without the use of a high power supply. Instead, a sequence of low power levels is supplied to a sequence of anodes in the electron beam path. The electron beam is thereby accelerated to a desired current density appropriate for the transmitter or receiver application without the need for a high-level power source.Type: ApplicationFiled: May 5, 2006Publication date: November 8, 2007Applicant: Virgin Islands Microsystems, Inc.Inventors: Jonathan Gorrell, Mark Davidson
