TL;DR: Combining power, area, and timing results of McPAT with performance simulation of PARSEC benchmarks for manycore designs at the 22nm technology shows that 8-core clustering gives the best energy-delay product, whereas when die area is taken into account, 4-core clusters give the best EDA2P and EDAP.
Abstract: This article introduces McPAT, an integrated power, area, and timing modeling framework that supports comprehensive design space exploration for multicore and manycore processor configurations ranging from 90nm to 22nm and beyond. At microarchitectural level, McPAT includes models for the fundamental components of a complete chip multiprocessor, including in-order and out-of-order processor cores, networks-on-chip, shared caches, and integrated system components such as memory controllers and Ethernet controllers. At circuit level, McPAT supports detailed modeling of critical-path timing, area, and power. At technology level, McPAT models timing, area, and power for the device types forecast in the ITRS roadmap. McPAT has a flexible XML interface to facilitate its use with many performance simulators.Combined with a performance simulator, McPAT enables architects to accurately quantify the cost of new ideas and assess trade-offs of different architectures using new metrics such as Energy-Delay-Area2 Product (EDA2P) and Energy-Delay-Area Product (EDAP). This article explores the interconnect options of future manycore processors by varying the degree of clustering over generations of process technologies. Clustering will bring interesting trade-offs between area and performance because the interconnects needed to group cores into clusters incur area overhead, but many applications can make good use of them due to synergies from cache sharing. Combining power, area, and timing results of McPAT with performance simulation of PARSEC benchmarks for manycore designs at the 22nm technology shows that 8-core clustering gives the best energy-delay product, whereas when die area is taken into account, 4-core clustering gives the best EDA2P and EDAP.

TL;DR: In this article, a logic circuit with electronic memory is used to monitor signal traffic with at least one client and a computer network to determine, without changing the signal traffic, for each client, a network address and a port to which that client is connected; access an authentication server that has a second table of user names and corresponding passwords for network login.
Abstract: An apparatus includes: a logic circuit with electronic memory to: monitor signal traffic with at least one client and a computer network to determine, without changing the signal traffic, for each client, a network address and a port to which that client is connected; provide to a first dynamic table the network address and port for each said client; access an authentication server that has a second table of user names and corresponding passwords for network login, in which the second table also includes for each user name and password a corresponding virtual local network (VLAN) membership and/or VLAN tag and/or Quality of Service (QoS); and add to the first dynamic table the user name, VLAN membership, VLAN tag and QoS information learnt from the authentication server in the second table.

TL;DR: The requirements for data integration flows in this next generation of operational BI system are described, the limitations of current technologies, the research challenges in meeting these requirements, and a framework for addressing these challenges are described.
Abstract: Business Intelligence (BI) refers to technologies, tools, and practices for collecting, integrating, analyzing, and presenting large volumes of information to enable better decision making. Today's BI architecture typically consists of a data warehouse (or one or more data marts), which consolidates data from several operational databases, and serves a variety of front-end querying, reporting, and analytic tools. The back-end of the architecture is a data integration pipeline for populating the data warehouse by extracting data from distributed and usually heterogeneous operational sources; cleansing, integrating and transforming the data; and loading it into the data warehouse. Since BI systems have been used primarily for off-line, strategic decision making, the traditional data integration pipeline is a oneway, batch process, usually implemented by extract-transform-load (ETL) tools. The design and implementation of the ETL pipeline is largely a labor-intensive activity, and typically consumes a large fraction of the effort in data warehousing projects. Increasingly, as enterprises become more automated, data-driven, and real-time, the BI architecture is evolving to support operational decision making. This imposes additional requirements and tradeoffs, resulting in even more complexity in the design of data integration flows. These include reducing the latency so that near real-time data can be delivered to the data warehouse, extracting information from a wider variety of data sources, extending the rigidly serial ETL pipeline to more general data flows, and considering alternative physical implementations. We describe the requirements for data integration flows in this next generation of operational BI system, the limitations of current technologies, the research challenges in meeting these requirements, and a framework for addressing these challenges. The goal is to facilitate the design and implementation of optimal flows to meet business requirements.

TL;DR: In this paper, a single sideband optical modulation at millimetre-wave frequencies using a fibre Bragg grating eliminates the dispersion-induced penalty over modulation frequency and fibre length.
Abstract: Dispersion causes a power penalty at certain fibre distances and frequencies in conventional millimetre-wave intensity modulation. Single sideband optical modulation at millimetre-wave frequencies using a fibre Bragg grating eliminates the dispersion-induced penalty over modulation frequency and fibre length.

TL;DR: In this paper, the authors present a method for remote control of a print queue in a network printer which receives print jobs over the Internet from plural client processors, which includes the steps of: establishing a queue of received print job identifiers, employing the server procedure to provide a first file to a client processor, to enable the client processor to transmit a status request concerning the print queue; receiving a message including the status request and transmitting, in response, a second file with queue data, the second file further including queue alteration choices.
Abstract: The method of the invention enables remote control of a print queue in a network printer which receives print jobs over the Internet from plural client processors. The network printer includes a server procedure which enables transfer of files from the network printer over the network and a browser procedure which enables retrieval of files from client processors over the network. The method includes the steps of: establishing a queue of received print job identifiers; employing the server procedure to provide a first file to a client processor to enable the client processor to transmit a status request concerning the print queue; receiving a message including the status request and transmitting, in response, a second file with queue data to the client processor, the second file further including queue alteration choices; receiving a response message from the client processor with at least one queue alteration value; and altering the queue accordingly. The method further includes the step of responding to a received URL from a scanner, by employing the browser procedure to retrieve a text file identified by the URL.
