Abstract: A measurement sampling facility takes snapshots of the central processing unit (CPU) on which it is executing at specified sampling intervals to collect data relating to tasks executing on the CPU. The collected data is stored in a buffer, and at selected times, an interrupt is provided to remove data from the buffer to enable reuse thereof. The interrupt is not taken after each sample, but in sufficient time to remove the data and minimize data loss.

Abstract: An aspect of the invention is a storage networking system comprising subsystems coupled with a network. The subsystems include an initiator subsystem having an initiator I/O (input/output) control unit, and a plurality of target subsystems each having a target I/O control unit. The initiator subsystem is configured to: place priority information in packet address of an I/O command packet, the priority information being based on a priority table; send the I/O command packet to one or more of the plurality of target I/O control units; and receive a return I/O packet from each of the target I/O control units that received the sent I/O command packet, the return I/O packet having the same priority information. The priority information provided in the priority table is priority of storing I/O data. The I/O data is transferred according to the priority information placed in the packet address of the I/O command packet.

Abstract: Data is processed in an embedded system by writing data read from a peripheral device in response to an event to memory external to the embedded system. The data or a portion of the data is copied to memory internal to the embedded system. Which portion of the data is stored in both the external memory and the internal memory is tracked. The copied data is retrieved from the internal memory by a processor included in the embedded system. The processor has one or more caches logically and physically separated from the internal memory. The processor uses the copied data it retrieved to begin servicing the event.

Abstract: During execution of an existing scheduling computer program on a client node, an update computer program and a self-describing automatic installation package are downloaded to the client node from a logical depot node implemented on an existing management server. Therefore, advantageously, no physical depot node or other additional computing device is needed for the client node to update itself. Execution of the update computer program is spawned on the client node from the existing scheduling computer program. As such, the update computer program inherits root access to the client node and security credentials to the management server from the scheduling computer program—advantageously, then, a user does not have to perform any laborious configuration of the client node in order to update the node. The client node ultimately updates itself using the self-describing automatic installation package, which includes all the information needed for the client node to update itself.

Abstract: According to an example embodiment of the present invention, a method is implemented for transmitting data between a Media Access Control Layer (MAC) (100) and a Physical Layer (PHY) (150) using an internal data bus for transmitting a set of internal symbols between the MAC (100) and PHY (150). A subset of internal symbols does not have a corresponding PHY symbol. An external data bus carries data symbols. An external interface (102, 118) provides command information on one or more dedicated command lines and provides the data symbols. An encoder (108, 110) encodes the provided command information into one or more of the subset of internal symbols. An internal interface (106, 107, 109, 111) transmits the one or more of the subset of internal symbols and the data symbols between the MAC (100) and PHY (150) using the internal data bus.

Abstract: Disclosed is a method and device for concurrently performing a plurality of data manipulation operations on data being transferred via a Direct Memory Access (DMA) channel managed by a DMA controller/engine. A Control Data Block (CDB) that controls where the data is retrieved from, delivered to, and how the plurality of data manipulation operations are performed may be fetched by the DMA controller. A CDB processor operating within the DMA controller may read the CDB and set up the data reads, data manipulation operations, and data writes in accord with the contents of the CDB. Data may be provided from one or more sources and data/modified data may be delivered to one or more destinations. While data is being channeled through the DMA controller, the DMA controller may concurrently perform a plurality of data manipulation operations on the data, such as, but not limited to: hashing, HMAC, fill pattern, LFSR, EEDP check, EEDP generation, XOR, encryption, and decryption.

Abstract: A method for converting traditional ladder diagrams for programmable controllers according to model 984, for example, the traditional ladder diagrams being read and executed column by column, into ladder diagrams for IEC 61131-oriented controllers, for example, with the ladder diagrams being read and executed in a data flow-oriented manner. In order to carry out the method, it is determined, in the ladder diagrams that are traditionally read and executed column by column, whether variables are provided on coils as well as on contacts within the network, and it is determined whether the contact is processed according to model 984 in front of the associated coil and according to the IEC model behind the associated coil. If so, an additional variable is generated for each such variable, and the additional variable is fed to the respective contact instead of the original variable.

Abstract: Embodiments of the present invention provide for an IOC that does not limit each CPU to a particular port. Instead, the IOC may allow each CPU to communicate with all ports. Thus, the IOC can process CPU communications to determine which port to send them to, and send them to the correct port as well as process incoming communications from the ports to determine which CPU to send them to and send these communications to the correct CPU. This may significantly increase the flexibility and efficiency of a storage network.
