Abstract: A mechanism is disclosed for establishing a separate virtual system console for each non-global zone of an operating system environment that has been partitioned into a global zone and one or more non-global zones. An operating system kernel instance implements a virtual console driver. A particular instance of the virtual console driver is executed. A device node is established within a non-global zone controlled by the kernel instance. An association is established between the device node and the particular virtual console driver instance. A process executes within the device node's non-global zone. In response to the process' request to write to the device node, it is determined which virtual console driver instance is associated with the device node. In response to determining that the device node is associated with the particular virtual console driver instance, data received from the process is sent to the particular virtual console driver instance.

Abstract: A computer-based method for improving the timely delivery of telemetry or other application-to-application data. A telemetry routing table is stored in memory that includes entries for a plurality of communication pathways for delivering a telemetry message from a telemetry application running on a first computer system to a telemetry reception application running on a second computer system.

Abstract: One embodiment of the present invention provides a system for generating an interconnection network. During operation, the system associates an n-bit binary identifier with each node in the interconnection network. The system also groups the n bits of each binary identifier into h overlapping sets a1, a2, . . . ah, wherein the sets a1, a2, . . . ah cover all of the n bits. For each set ai, the system forms fully connected clusters of nodes by creating a direct point-to-point link between any two nodes that have binary identifiers that differ in bits of the set a1 but are the same in other bit positions. Note that by varying the amount of overlap and the pattern of overlap between the overlapping sets, a1, a2, . . . ah, the interconnection network can be configured to accommodate different redundancy requirements.

Abstract: The clock signal is the dominant source of electromagnetic interference (EMI) for many digital electronic devices. EMI generated by these electronic devices must be suppressed to avoid interference with other electronic devices and to satisfy FCC regulations. The present invention seeks to reduce EMI emissions by phase-modulating the clock signal using tunable delay lines. Phase modulation causes a spreading of the energy spectrum of the clock signal thereby reducing EMI emissions. In addition, the present invention is capable of generating a wide energy spectrum in a short time interval. Furthermore, the present invention can be similarly applied to other signals which exhibit a periodic or timing nature due to a correlation with the clock signal.

Abstract: Computing devices are tested by providing a suite of test programs on a server for execution by a plurality of identical computing devices that are coupled to the server. A respective unique identifier is assigned to each of the plurality of the computing devices, for use in communicating with the server. The test programs are downloaded from the server for execution by the computing devices coupled thereto, so that at different computing devices execute different test programs substantially simultaneously. The server receives messages from the computing devices with respect to execution of the test programs, each of the messages containing the respective unique identifier, and controls the execution of the test programs in the suite based on the messages. The server dynamically distributes the test programs to a changing population of the computing devices, optimizing the distribution so as to minimize the time to complete the suite.

Abstract: One embodiment of the present invention provides a system for distributing signals through a jig-plate in a computer system. The jig-plate contains alignment features that assist in positioning semiconductor chips in relation to the jig-plate. In addition, the jig-plate contains one or more embedded signal routing layers. These metal routing layers provide one or more signal routes for the distribution of signals through the jig-plate to semiconductor chips which have been aligned with the jig-plate. Note that routing the signals through the jig-plate facilitates the distribution of the signals without requiring that the signals be routed through the semiconductor chips in the jig-plate.

Abstract: A packet stream multiplexer may include one or more control loops (e.g., digital phase locked loops) for tracking the source clock frequency associated with a packet stream. A first control loop may slowly drive an error between a received timestamp and an estimated timestamp to zero. A second control loop may more quickly drive a first derivative of the error to zero. The second control loop may include a set of digital filters ordered according to tracking speed. The output of the slowest filter is initially selected for updating the source clock frequency estimate. As time progresses, the faster filters are selected in succession. The estimated source clock frequency is used to restamp packets of the packet stream as they are sent out onto an output channel.
