摘要： One embodiment of the present invention provides a system that facilitates changing a clock frequency in a memory system. During operation, the system receives a command to change the clock frequency to a new clock frequency. The system then iteratively changes the clock frequency to the new clock frequency. More specifically, the system starts an iteration by slewing the clock frequency toward the new clock frequency by an increment to reach an intermediate frequency without interfering with normal memory-system operation. Next, the system signals a memory controller to pause normal memory system operation by completing or cancelling all in-flight or outstanding memory system operations and not accepting additional memory operation requests. Upon receiving an acknowledgement from the memory controller that all in-flight or outstanding memory operations have completed or terminated, the system signals the memory controller to cause a delay-locked loop (DLL) inside the memory system to relock to the intermediate frequency. When the DLL relocks to the intermediate frequency, the system completes the iteration by resuming normal memory system operation.

摘要： One embodiment of the present invention provides a method and a system for tracking memory usage of tasks in a shared heap. The system performs a full garbage-collection operation on the shared heap, during which a base memory usage is determined for each task. The system then periodically samples task state during execution to generate an estimate of newly allocated memory for each task. The base memory usage and the estimate of newly allocated memory for each task are combined to produce an estimate of current memory usage for each task. This estimate of current memory usage is used to determine whether a task is likely to be violating a memory quota. If so, the system triggers a remedial action, which can include: a full garbage-collection operation; a generational garbage-collection operation; or generation of a signal which indicates that a memory quota violation has occurred.

摘要： A system and method for inducing asynchronous behavioral changes in a managed application process is presented. An application manager process is executed. A managed application process is executed. At least one application provided as object-oriented program code under the control of a managed code platform is executed. The managed application process logically communicates with the application manager process. One or more constructors corresponding to notifiable objects provided as object-oriented program code are identified. Each constructor keeps track of instantiated notifiable objects in a list in the managed application process. A change request is broadcast to the managed application process. The notifiable objects tracked by each identified constructor are iterated over to effect a behavioral change in the managed application process.

摘要： One embodiment of the present invention provides a system that supports executing a fail instruction, which terminates transactional execution of a block of instructions. During operation, the system facilitates transactional execution of a block of instructions within a program, wherein changes made during the transactional execution are not committed to the architectural state of the processor until the transactional execution successfully completes. If a fail instruction is encountered during this transactional execution, the system terminates the transactional execution without committing results of the transactional execution to the architectural state of the processor.

摘要： A system that communicates with an embedded controller within a computing device. During operation, the system queries the embedded controller to obtain information describing an interface for interacting with a functionality provided by the embedded controller. The system then receives a response from the computing device which includes a reference to a metadata object describing the interface. If the metadata object refers to other metadata objects, the system recursively queries the embedded controller to obtain information about the other metadata objects until a complete description of the interface is obtained.

摘要： A system and methods for applying capability-based authorization within a distributed computing environment. Instead of associating permissions or privileges with objects (e.g., computing resources), permissions are associated with subjects (e.g., users, roles). Compared to object-based methods of access control, such as Access Control Lists (ACL), management of capability-based authorizations scales much better as the number of objects becomes very large. A central repository allows changes to the authorization framework (e.g., new subjects, modified permissions) to be made once. The changes can then be propagated across, and applied to, multiple address spaces instead of having to individually or manually update each local node or address space.

摘要： One embodiment of the present invention provides a system that communicates cryptographic data through multiple network layers. During operation, the system receives the cryptographic data and divides the cryptographic data into multiple pieces. The system then encapsulates different pieces of the cryptographic data into fields associated with different network layers in a data packet, whereby an item of cryptographic data that is too large to be communicated in a single field can be communicated through multiple fields associated with different network layers.

摘要： One embodiment of the present invention provides a system that transparently interconnects multiple network links into a single virtual network link. During operation, a Rbridge (Rbridge) within the system receives a packet, wherein the Rbridge belongs to a set of one or more Rbridges that transparently interconnect the multiple network links into the single virtual network link. These Rbridges automatically obtain information specifying which endnodes are located on the multiple network links without the endnodes having to proactively announce their presence to the Rbridges. If a destination for the packet resides on the same virtual network link, the Rbridge routes the packet to the destination. This route can be an optimal path to the destination, and is not constrained to lie along a spanning tree through the set of Rbridges.

摘要： One embodiment of the present invention provides a system for operating a key distribution center (KDC) that provides keys to facilitate secure communications between clients and servers across a computer network, wherein the system operates without having to store long-term server secrets. The system operates by receiving a communication from a server at the KDC. This communication includes an identifier for the server, as well as a temporary secret key to be used in communications between a client and the server for a limited time period. In response the communication, the system attempts to authenticate the server. If the server is successfully authenticated, the system stores the temporary secret key at the KDC, so that the temporary secret key can be subsequently used to facilitate communications with the server. Upon subsequently receiving a request at the KDC from a client that desires to communicate with the server, the system produces a session key to be used in communications between the client and server, and then creates a ticket to the server by encrypting an identifier for the client and the session key with the temporary secret key for the server. Next, the system assembles a message that includes the identifier for the server, the session key and the ticket to the server, and sends the message to the client in a secure manner. The system subsequently allows the client to forward the ticket to the server in order to initiate communications between the client and the server.

摘要： One embodiment of the present invention provides a system that optimizes synchronization between monitored signals in a computer system. During operation, the system receives a number of monitored signals. The system then forms a number of signal pairs by grouping each signal with every other signal. Next, the system optimizes synchronization between the signals by iteratively perturbing the timing of each signal in an attempt to increase the value of an objective function which reflects the overall synchronization between all the signals.
