摘要： A stream processing execution engine evaluates development-time performance characteristic estimates in combination with run-time parameters to schedule execution of stream processing software components in a stack of a stream processing application that satisfy a defined performance criterion in a heterogeneous hardware device. A stream processing application includes a stack of interdependent stream processing software components. A stream processing execution engine evaluates one or more performance characteristics of multiple computational resources in the heterogeneous hardware device. Each performance characteristic is associated with performance of a computational resource in executing a computational-resource-dependent instance of a stream processing software component. The stream processing execution engine schedules within the run-time environment a computational resource on which to execute a computational-resource-dependent instance of one of the stream processing software components. The computational-resource-dependent instance is targeted for execution on the computational resource that satisfies a performance policy attributed to the stream processing software component.

摘要： A framework capable of providing transparent handling of network traffic in close proximity networks such as home networks is provided. A single virtual network interface is exposed to users/applications on connected devices. A virtual network interface manager determines available physical network interfaces and switches to a different physical network interface or a different configuration on the same physical network interface in a transparent manner to the communicating application(s). This enables the framework to optimize network communications for the communicating applications, devices, and users based on predefined criteria, application requirements such as different data throughput, or changing environment conditions such as interference. Network communication operations are also simplified for users since they are no longer required to have the necessary knowledge for configuring physical network interfaces manually in response to changing conditions.

摘要： A method including transmitting a binary vector from a source node to a relay node and receiving a signal vector at the relay node. The method also includes compressing the signal at the relay node by multiplying the signal with a matrix using probabilities and converting output probabilities from the multiplying into retransmission signal amplitudes, the signal amplitude depending not only on a probability of a bit but on a transmission power constraint at the relay node. The method also includes transmitting, by the relay node, estimates of information from the source node to a destination node.

Decoding is performed in a pipelined manner using an irregular, block-structured parity check matrix, where at least two data sub-block matrices of the parity check matrix are read from and written in each of a plurality of clock cycles. The reading and writing of the data sub-blocks is evenly distributed between at least two area of a memory.
