Performance monitor (PM) support in on-chip PowerPC@’ microprocessors is used to analyze processor, software, and system attributes for a variety of workloads. The interface to the PowerPC 604@ microprocessor, which we abbreviate “604,” has been externalized to end users. We discuss the enhanced PM support available in an upgrade of the 604, the PowerPC m e T M microprocessor, which we abbrevia...

Nowadays Applications based on web services as interaction interface/application programming interface are becoming more and more popular. One of its merits is that it’s platform-independent and implementation-independent, which makes it possible to build new web services automatically just by composing existing ones to meet some coming requirements. To ease this work, it is important to classi...

Status of this Memo This RFC specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" for the standardization state and status of this protocol. Distribution of this memo is unlimited. Abstract This Generic Security Service Application Pro...

We present WebVectors, a toolkit that facilitates using distributional semantic models in everyday research. Our toolkit has two main features: it allows to build web interfaces to query models using a web browser, and it provides the API to query models automatically. Our system is easy to use and can be tuned according to individual demands. This software can be of use to those who need to wo...

This paper presents an application programming interface (API) for users to select and activate multime-dia services in a multivendor environment. This API hides the complexities and details of handling these complex services from the application developers. An abstract model has been deened that accommodates an extensive set of services involving communication and end-systems. The paper deenes...

Reducing their energy consumption has become an important concern for many people lately. A necessary step to save energy is to raise consumption awareness, that is: to realize how much electricity is consumed by household appliances. We propose a system that uses and extends intelligent power outlets called Plogg, which contain sensor nodes to wirelessly measure the energy consumption of vario...

A characteristic of urban sensing is that applications need to compose the operations and fuse information from sensing fabrics extant in the environment, to meet requirements for which the fabrics were not designed a priori. We propose an architecture, WEAVE, that allows tailoring of applications across one or more urban sensing fabrics. Key to the architecture is use of standard application p...

The Berkeley Continuous Media Toolkit provides low-level, modular tools for developing distributed continuous media (CM) applications. The programming interface to the toolkit requires application developers to create and manage objects required to play back audio and video. These objects are distributed to di erent processes possibly on di erent hosts. This paper presents an application progra...

A new application programming interface for evaluating functions and specifying optimization problems at runtime has been developed. The new interface, named FEFAR, uses a simple language named LEFAR. Compared with other modeling languages such as AMPL or OSil, LEFAR is Fortranlike hence easy to learn and use, in particular for Fortran programmers. FEFAR itself is a Fortran subroutine hence eas...
