Abstract: One embodiment can provide a method and system for compensating for timing skew in a differential pair transmission line on a printed circuit board (PCB). During operation, the system obtains a PCB comprising one or more layers and at least a differential pair transmission line. The differential pair transmission line comprises first and second transmission lines, with a respective transmission line coupled to at least one via extending through the one or more layers of the PCB. The system determines a difference in length between first and second transmission lines and determines a stub length of the at least one via based on the determined difference in length between the first and second transmission lines, thereby compensating for the time skew in the differential pair transmission line.

Abstract: A method and system for identifying results of a query that includes a type predicate is provided. A search system maintains a collection of facts that includes a triple for each fact and a type table that maps entities of the facts to their corresponding type. The search system uses the type table to speed up the process of identifying the search results when the query includes a non-type query triple and a type query triple. A type query triple is a triple that has a type predicate, rather than a non-type predicate. To execute a query that contains a non-type query triple and a type query triple, the search system identifies the triples of the collection that match the non-type query triple. The search system then uses the type table to determine which of the identified triples match the type query triple for inclusion in the search results.

Abstract: A system and algorithm configured to generate diversity at the traffic source so that packets are uniformly distributed over all of the available paths, but to increase the likelihood of taking a minimal path with each hop the packet takes. This is achieved by configuring routing biases so as to prefer non-minimal paths at the injection point, but increasingly prefer minimal paths as the packet proceeds, referred to herein as Increasing Minimal Bias (IMB).

Abstract: To eliminate signal loss and sources of signal attenuation, a connection methodology is utilized which enables high-speed signals to be directly communicated from particular integrated circuits housed on a printed circuit board, to other locations within a system. More specifically, a signal escape strategy directly connects a high-speed cable to a point on the circuit board which is very close to the integrated circuit itself. A back-side connection methodology is utilized so that electrical signals pass directly from the integrated circuit through a via, to a connection point on the backside of the circuit board. To accommodate this connection, a specially designed interposer and related paddle cards are utilized so the high-speed communication cable can be easily attached.

Abstract: A graph analysis system provides a variety of graph analysis tools for analyzing graphs, such as an overall characteristics report, an entity types graph, an ego entity type graph, various histograms, and graph comparison reports. The graph analysis tools also include tools for calculating a similarity score for graphs based on characteristics and weights selected by a user.

Abstract: A circuit assembly is provided which makes efficient us of space provided on a main board having a CPU and a supporting board which is designed to have a network interface chip (NIC). The circuit assembly further has a cooling plate situated between the two boards, which is optimized to provide efficient cooling operations. The circuit assembly is part of a blade, which includes a housing to contain and support all necessary components. The space within the blade housing is efficiently used, so that processing, communication and cooling operations are all optimized.

Abstract: A system for providing cross-exception event handling is provided. The system allows a source thread to throw an event (e.g., exception) as part of structured event handling of a programming language that specifies a target thread. When the event is thrown, the source thread starts a handler thread to handle the event in a current context of the target thread. The handler thread is passed an indication of the event and the target thread and sets its context to be consistent with that of handling events in the target thread. The handler thread then handles the event. The source thread may continue its execution in parallel or may terminate its execution as specified in a statement that threw the event. Execution of the target thread may be aborted and its execution continued at an exit statement of an enclosing structured event handling construct—as specified when the event was thrown.

Abstract: Computer systems having heat exchangers for cooling computer components are disclosed herein. The computer systems include a computer cabinet having an air inlet, an air outlet spaced apart from the air inlet, and a plurality of computer module compartments positioned between the air inlet and the air outlet. The air inlet, the air outlet, and the computer module compartments define an air flow path through the computer cabinet. The computer systems also include a heat exchanger positioned between two adjacent computer module compartments. The heat exchanger includes a plurality of heat exchange elements canted relative to the air flow path.
