Abstract: An integrated circuit (IC) includes a first I/O cell, a logic cell, a trigger signal generation circuit, and a second I/O cell having a voltage selection pin. I/O interfaces of the first I/O cell receive first and second supply voltages, respectively, and I/O interfaces of the second I/O cell receive third and fourth supply voltages, respectively. The first I/O cell generates a first trigger signal when the first supply voltage reaches a first predetermined voltage. The logic cell receives the first trigger signal and generates a safe-state signal. The trigger signal generation circuit generates a second trigger signal when the third supply voltage reaches a second predetermined voltage. The voltage selection pin receives the safe-state signal and the second trigger signal and sets the second I/O cell in a safe-state mode, which protects the second I/O cell from over voltage damage.

Abstract: A technique for performing stream output operations in a parallel processing system is disclosed. A stream synchronization unit is provided that enables the parallel processing unit to track batches of vertices being processed in a graphics processing pipeline. A plurality of stream output units is also provided, where each stream output unit writes vertex attribute data to one or more stream output buffers for a portion of the batches of vertices. A messaging protocol is implemented between the stream synchronization unit and the plurality of stream output units that ensures that each of the stream output units writes vertex attribute data for the particular batch of vertices distributed to that particular stream output unit in the same order in the stream output buffers as the order in which the batch of vertices was received from a device driver by the parallel processing unit.

Abstract: A security infrastructure and methods are presented that inhibit the ability of a malicious node from disrupting the normal operations of a peer-to-peer network. The methods of the invention allow both secure and insecure identities to be used by nodes by making them self-verifying. When necessary or opportunistic, ID ownership is validated by piggybacking the validation on existing messages. The probability of connecting initially to a malicious node is reduced by randomly selecting to which node to connect. Further, information from malicious nodes is identified and can be disregarded by maintaining information about prior communications that will require a future response. Denial of service attacks are inhibited by allowing the node to disregard requests when its resource utilization exceeds a predetermined limit. The ability for a malicious node to remove a valid node is reduced by requiring that revocation certificates be signed by the node to be removed.

Abstract: Technologies are described herein for relevance-based expiration of data. An initial expiration time for the data is computed based upon an expiration duration associated with the data. The expiration time for the data is periodically re-computed in order to extend the expiration time. A relevance value for the meeting data is computed and the expiration time is set as a function of the computed relevance value. The relevance value may be computed as a product of a user-settable relevance value for the meeting data and a dynamic relevance point for the meeting data. When the computed expiration time for meeting data has been reached, the meeting data is expired, such as through the deletion of the meeting data.

Abstract: A system and method for providing security to a graph of interconnected nodes includes a grouping multiplexing layer configured to monitor calls to the system, a graphing dynamic link layer configured to transmit and receive data to and from the graph, and a group security manager coupled to the grouping multiplexing layer and coupled to the graphing dynamic link layer; the group security manager is configured to perform security-related acts via interacting with a group database to propagate security-related information to members of a group within the graph. The group security manager is configured to provide role-based authorization on publication of one or more records and provide membership control for admission to a graph of interconnected nodes. The group security manager provides membership control by providing credentials to potential members of the graph to enable a connection and by providing a governed system for renewal and revocation of members.
