Abstract: An information processing module, for example a server blade, has information connections and storage connections. A carrier, e.g., a rack mountable shelf, is configured to receive a number of information processing modules. A switch module is operable to connect a received information processing module to an external information network. The switch includes an external storage connection operable under an external storage channel format, e.g., Fiber Channel. A protocol converter converts between information packets comprising packet format storage data (e.g., iSCSI format) received from an information processing module and signals in the external storage channel format. Redundant connections are included to enhance reliability.

Abstract: One embodiment of the present invention facilitates skewing a bi-directional object layout to provide good cache behavior. During operation, the system receives a request to access an object. This request includes an object identifier and an object offset that specifies the offset of a target field within the object, wherein the object has a bi-directional layout that locates scalar fields at positive offsets and reference fields at negative offsets, so that a reference field can be immediately identified from its object offset. Next, the system determines a skew value for a cache line containing the object, wherein data within the cache line is shifted based upon the skew value, so that reference fields with small negative offsets are likely to be located in the same cache line as scalar fields with small positive offsets. Next, the system uses the skew value in accessing the object.

Abstract: A heat sink operatively connected to an integrated circuit is configured to generate a magnetic field. Fluid flow toward and away from a hot spot of the integrated circuit is dependent on the magnetic field and an induced electrical current. A temperature sensor is used to take temperature measurements of the hot spot. A value of the induced electrical current is adjusted dependent on one or more temperature measurements taken by the temperature sensor.

Abstract: One embodiment of the present invention provides a system that facilitates loading classes into non-volatile memory. During the loading process, the system first loads class definitions into volatile memory, wherein the class definitions contain metadata for classes currently being loaded into non-volatile memory, as well as metadata for classes that are already loaded into non-volatile memory. Next, after the class definitions are loaded into volatile memory, the system loads method code for the classes into non-volatile memory. During this process, the system uses the class definitions to resolve linkages in the method code so that the method code is ready for execution in non-volatile memory.

Abstract: A static random access memory (SRAM) unit is provided having a read control module, a write control module, and a bypass. The read control module is configured to communicate a read signal defined to read from a first address in the SRAM unit. The write control module is configured to communicate a write signal defined to write to a second address in the SRAM unit. The bypass is disposed to connect the write control module to the read control module. The bypass is further configured to prevent a simultaneous communication of the read signal and the write signal when the first address and the second address are equivalent.

Abstract: The time cost of collecting a region in a Garbage-First garbage collector is adjusted to account for concurrent thread activity. The overhead of a concurrent thread is tracked by dividing elapsed time into relatively short time “windows” and monitoring the system during those windows to determine how long that thread is scheduled to run during those windows. Using measurements of this type for each concurrent thread, the percentage of each elapsed time window dedicated to each concurrent thread is determined. Finally, by summing the percentages of elapsed time dedicated to concurrent thread activity, the cost of collecting a region can be increased by adding the overhead attributable to concurrent activity.

Abstract: A secure interface between clients and services in a distributed computing environment is described. Method gates may provide an interface to remotely invoke functions of a service. A method gate may be generated from an advertisement that may include definitions for one or more messages for remotely invoking functions of the service. A client may generate messages containing representations of method calls. The service may invoke functions that correspond to the set of messages. A method gate on the service may unmarshal the message and invoke the function. The client may receive the results of the function directly. Alternatively, the results may be stored, an advertisement to the results may be provided, and a gate may be generated to access the results. Message gates may perform the sending and receiving of the messages between the client and service. In one embodiment, functions of the service may be computer programming language (e.g. Java) methods.

The known signal dataset includes a signal value for at least one signal that describes an operating condition of one of a plurality of subject data processing systems. A new signal dataset having an entry for each monitored signal and a corresponding signal value is prepared simultaneously with monitoring the plurality of signals and determining whether there is a problem.

Abstract: An apparatus that minimizes phase error and jitter in a phase-locked loop. The apparatus includes a phase/frequency detector, a charge pump, a loop filter, a voltage-controlled oscillator, and a frequency divider, which are coupled together to form a phase-locked loop. The charge pump within the phase-locked loop contains a pull-up network and a pull-down network which are coupled to each other, and a current compensation device. If the pull-up network and the pull-down network are both conducting, the current compensation device adjusts currents flowing through the pull-up network and through the pull-down network such that the currents are substantially equal. This ensures that very little current flows into the loop filter, thereby substantially minimizing a build-up of charge on a capacitor in the loop filter, which can cause phase error and jitter in the phase-locked loop.
