Abstract: Embodiments of an optical device, an array of optical devices, and a technique for fabricating the optical device or the array are described. This optical device is implemented on a substrate (such as silicon), and includes a thermally tunable optical waveguide that has good thermal isolation from its surroundings. In particular, a portion of a semiconductor in the optical device, which includes the optical waveguide, is free standing above a gap between the semiconductor layer and the substrate. By reducing the thermal coupling between the optical waveguide and the external environment, the optical device can be thermally tuned with significantly less power consumption.

Abstract: A virtual zone management framework manages one or more virtual computing zones forming a global computing zone residing on a host computer. The virtual zone manager comprises a normalization engine, a zone probe, and an interface engine that manages each virtual computing zone residing on the host computer. The virtual zone manager manages the services operating on each virtual zone while simultaneously managing the global computing environment using probes and/or agents to gather data and zone characteristics in response to a triggering event. Once data of interest are gathered for each zone, they are normalized so as to present a consistent and compatible representation of the characteristics with respect to the other virtual computing zones. Based on a comparison and analysis of the normalized characteristics, the virtual zone manager manages each of the virtual zones within the global computing environment as well as the global computing environment itself.

Abstract: In one embodiment, a method for efficiently classifying packets for a multi-processor/mutli-thread environment is provided. The method initiates with receiving a packet. Then, header information is extracted form the received packet. Next, a first hash value is calculated. Then, a field of interest in a lookup table is determined from the first hash value. Next, a second hash value is calculated. Then, the second hash value is compared to stored hash values in the field of interest of the lookup table to determine a match between the second hash value and one of the values in the field of interest of the lookup table. If there is a match, the received packet is transmitted to a processor corresponding to the one of the values in the row location of the lookup table. A network interface card and a system for efficiently classifying packets in a multicore/multithread environment are also provided.

Abstract: Architectural support for generation isolation is provided through trapping of intergenerational pointer stores. Identification of pointers stores as intergenerational is performed by a store barrier responsive to an intergenerational pointer store trap matrix that is programmably encoded with store target object and store pointer data generation pairs to be trapped. The write barrier and intergenerational pointer store trap matrix provide a programmably-flexible definition of generation pairs to be trapped, affording a garbage collector implementer with support for a wide variety of generational garbage collection method, including remembered set-based methods, card-marking type methods, write barrier based copying collector methods, etc., as well as combinations thereof and combinations including train algorithm type methods to managing mature portions of a generationally collected memory space. Pointer specific store instruction replacement allows implementations in accordance with this invention to provide an exact barrier to not only pointer stores, but to the specific intergenerational pointer stores of interest to a particular garbage collection method or combination of methods.

Abstract: A pointer-specific instruction variant replacement mechanism facilitates an exact write barrier, i.e., a write barrier specific to pointer stores and transparent to non-pointer stores. Pointer store specific instruction replacement allows some implementations to provide an exact barrier specific to the particular set of intergenerational pointer stores that are of interest to a particular garbage collection method or combination of methods. The exact identification of pointer stores herein does not require tags encoded in-line with collected memory storage and does not require non-standard word sizes to support such tags. In one embodiment, a non-quick to quick translator cache provides pointer specific store instruction replacement. In another, self-modifying code provides pointer specific store instruction replacement. An exemplary write barrier provided in accordance with the pointer-specific instruction variant replacement mechanism of this invention affords a garbage collector implementer with support for a wide variety of garbage collection methods, including remembered set-based methods, card-marking type methods, write barrier based copying collector methods, mark-sweep methods, etc., as well as combinations thereof and combinations including train algorithm type methods to managing mature portions of a generationally collected memory space. Such a write barrier can eliminate non-pointer stores from the set of stores that are evaluated against, for example, an intergenerational pointer store trap matrix or a garbage collection page mask to determine whether or not to trap. Such a write barrier can also eliminate entries associated with non-pointer stores from remembered set or card table stores for collection time scanning of modified portions of a collected generational space.

Abstract: A method for securing a commercial grid network over non-trusted routes involves receiving, by an administrative node in the commercial grid network, a lease request from a client to lease one of multiple resource nodes in the commercial grid network, wherein the client is separated from the resource node by a non-trusted route. The method further involves transmitting, by the administrative node, a network security key associated with the client to the resource node, storing, by the resource node, the network security key in a network security key repository specific to the resource node, establishing, by the resource node, a secure network tunnel over the non-trusted route using the network security key, transmitting a network packet securely between the client and the resource node over the secure network tunnel, and destroying, by the resource node, the secure network tunnel when a lease term associated with the client and the resource node expires.
