Abstract: A method includes determining, by a processor, that a write request indicates a clone file that was cloned from a file in a first fileset. The clone file is of a second fileset and a clustered file system comprises the first fileset and the second fileset. A data block of the clone file affected by the write request is determined. The method includes determining that the data block at a current location cannot be modified. In response to a determination that the data block at the current location cannot be modified, the method includes implementing the write request with respect to the data block at a different location and indicating that the data block at the different location can be modified for subsequent write requests that indicate the clone file.

Abstract: A cluster server manages allocation of free blocks to cluster clients performing writes in a clustered file system. The cluster server manages free block allocation with a free block map and an in-flight block map. The free block map is a data structure or hardware structure with data that indicates blocks or extents of the clustered file system that can be allocated to a client for the client to write data. The in-flight block map is a data structure or hardware structure with data that indicates blocks that have been allocated to clients, but remain in-flight. A block remains in-flight until the clustered file system metadata has been updated to reflect a write performed to that block by a client. After a consistency snapshot of the metadata is published to the storage resources, the data at the block will be visible to other nodes of the cluster.

The isolation barrier contains an organic and/or a semi-organic insulating material with at least one capacitor embedded inside. One of the two metal support paddles is located below a first portion of a bottom surface of the isolation barrier to provide support to the isolation barrier, while the other metal support paddle is located below a second portion of a bottom surface of the isolation barrier to provide support to the isolation barrier.

Abstract: After a clone file is created from a file, a write request targeting the clone file can be handled. It is determined that the write request indicates the clone file that was cloned from a file in a first fileset. The clone file is of a second fileset and a clustered file system comprises the first fileset and the second fileset. A data block of the clone file affected by the write request is determined. It is then determined that the data block at a current location cannot be modified. The write request is implemented with respect to the data block at a different location. It is indicated that the data block at the different location can be modified for subsequent write requests that indicate the clone file.

Abstract: A method includes initiating committing to persistent storage of a current consistency snapshot of a plurality of data objects in a redirect-on-write file system. Each of the plurality of data objects has a first copy of at least two copies of the data having a first context of at least two contexts. The method includes receiving, during committing to storage of the current consistency snapshot, an update to a data object of the plurality of data objects. The method also includes responsive to receipt of the update to the data object, creating a second copy of data of the data object from the first copy. The second copy of the data has a second context of the at least two contexts. The method includes responsive to receipt of the update to the data object, updating, based on the update, the second copy of the data of the data object.

Abstract: Management of a file hierarchy for a clustered file system can be distributed across nodes of the cluster. A cluster file hierarchy is accessed to determine location of a file in response to a request to write to a file. A first node maintains the cluster file hierarchy. It is determined that management of a fileset object, which represents a fileset that includes the file, has been delegated to a second node based, at least in part, on said accessing the cluster file hierarchy. A node file hierarchy maintained by the second node is accessed responsive to determining the delegation. The cluster file hierarchy represents filesets of the clustered file system and the node hierarchy represents a subset of one or more of the filesets. Location of the file is determined based, at least in part, on said accessing the node file hierarchy.

Abstract: Methods to allow, suppress, or reformulate a presentation of a UI element invoked by a computer program are provided. One method includes applying an administrator-configurable heuristic to determine whether to allow a native presentation of the UI element, to suppress the native presentation of the UI element, or to enable a reformulated presentation of the UI element. The method further includes one or more of suppressing and reformulating the UI element in accordance with a determination of the heuristic.

Abstract: An on-chip sensor measures dynamic power supply noise, such as voltage droop, on a semiconductor chip. In-situ logic is employed, which is sensitive to noise present on the power supply of functional logic of the chip. Exemplary functional logic includes a microprocessor, adder, and/or other functional logic of the chip. The in-situ logic performs some operation, and the amount of time required for performing that operation (i.e., the operational delay) is sensitive to noise present on the power supply. Thus, by evaluating the operational delay of the in-situ logic, the amount of noise present on the power supply can be measured.

Abstract: The present invention provides a heat control plate and a battery cell module having the same. The heat control plate is used as an interfacial component interposed between battery cells. The heat control plate includes a planar composite sheet, a plurality of heat radiating ribbons, a planar heating layer, and a conductive strap. The plurality of heat radiating ribbons penetrate the composite sheet and protrude from both right and left sides of the composite sheet at both ends thereof. The planar heating layer is attached to one or both of upper and lower surfaces of the composite sheet and generates heat upon application of a voltage. The conductive strap applies a supply voltage to the planar heating layer. The planar composite sheet can have a high thermal conductivity. The planar composite sheet can have a thermal conductivity greater than about 3 W/mK.

Abstract: One embodiment is for using a sparse file as a clone. The method includes creating, by an application associated with a computer system, a snapshot of a file, such as an individual file, a collection of files, file system, directories, and so forth. Further, the method includes requesting, by the application, a clone of that created snapshot. Further still, the method includes generating, by the application, an empty sparse having at least one inode identifying the empty sparse file as the clone and pointing to the snapshot associated with the clone. Thereby, the requested clone is created using the created sparse file, which begins as an empty sparse file.

Abstract: A communication system includes a hybrid signal transmitter incorporating a signal routing circuit and a driver circuit. The signal routing circuit is configured to receive a first input signal and route the first input signal through a first signal path when the frequency bandwidth of the input signal is lower than a threshold frequency and through a second signal path when the frequency bandwidth exceeds the threshold frequency. The second signal path includes a frequency down-converter circuit. The driver circuit is configured to receive the routed input signal via the first signal path or the second signal path, and convert the routed input signal into an optical signal for coupling into an optical fiber.
