System and method for layering drivers

Abstract: A system and method for incorporating intermediate link layer drivers into a network protocol stack is presented. The system and method utilize an abstract interface for interfacing both inputs and outputs of intermediate drivers and for providing an interface for link layer device drivers. The abstract interface provides routing of data packets through the intermediate drivers and device drivers to facilitate the desired data flow. The abstract interface facilitates reuse and portability of intermediate drivers across varying computer platforms. Layering of intermediate drivers also accommodates data flow modification with minimal impact to existing drivers.

PerfSuite: An Accessible, Open Source Performance Analysis Environment for Linux

Abstract: The motivation, design, implementation, and current status of a new set of software tools called PerfSuite that is targeted to performance analysis of user applications on Linux-based systems is described. These tools emphasize ease of use/deployment and portability/reuse in implementation details as well as data representation and format. After a year of public beta availability and production deployment on Linux clusters that rank among the largest-scale in the country, PerfSuite is gaining acceptance as a user-oriented and flexible software tool set that is as valuable on the desktop as it is on leading-edge terascale clusters.

Software tools in Pascal

Abstract: From the Publisher: With the same style and clarity that characterized their highly acclaimed The Elements of Programming Style and Software Tools, the authors have written Software Tools in Pascal to teach how to write good Pascal programs that make good tools The programs contained in the book are not artificial, but are actual tools that have proved valuable in the production of other programs Structured programming and top-down design are emphasized and applied to every program, as are principles of sound design, testing, efficiency, and portability All of the programs are complete and have been tested directly from the text The programs are available in machine-readable form from Addison-Wesley Software Tools in Pascal is ideal for use in a software engineering course, for a second course in programming, or as a supplement in any programming course All programmers, professional and student, will find the book invaluable as a source of proven, useful programs for reading and study Numerous exercises are provided to test comprehension and to extend the concepts presented in the book 0201103427B04062001

Addressing ontology-based question answering with collections of user queries

Abstract: This paper presents QACID an ontology-based Question Answering system applied to the CInema Domain. This system allows users to retrieve information from formal ontologies by using as input queries formulated in natural language. The original characteristic of QACID is the strategy used to fill the gap between users' expressiveness and formal knowledge representation. This approach is based on collections of user queries and offers a simple adaptability to deal with multilingual capabilities, inter-domain portability and changes in user information requirements. All these capabilities permit developing Question Answering applications for actual users. This system has been developed and tested on the Spanish language and using an ontology modelling the cinema domain. The performance level achieved enables the use of the system in real environments.

A work-stealing scheduler for X10's task parallelism with suspension

Abstract: The X10 programming language is intended to ease the programming of scalable concurrent and distributed applications. X10 augments a familiar imperative object-oriented programming model with constructs to support light-weight asynchronous tasks as well as execution across multiple address spaces. A crucial aspect of X10's runtime system is the scheduling of concurrent tasks. Work-stealing schedulers have been shown to efficiently load balance fine-grain divide-and-conquer task-parallel program on SMPs and multicores. But X10 is not limited to shared-memory fork-join parallelism. X10 permits tasks to suspend and synchronize by means of conditional atomic blocks and remote task invocations.In this paper, we demonstrate that work-stealing scheduling principles are applicable to a rich programming language such as X10, achieving performance at scale without compromising expressivity, ease of use, or portability. We design and implement a portable work-stealing execution engine for X10. While this engine is biased toward the efficient execution of fork-join parallelism in shared memory, it handles the full X10 language, especially conditional atomic blocks and distribution.We show that this engine improves the run time of a series of benchmark programs by several orders of magnitude when used in combination with the C++ backend compiler and runtime for X10. It achieves scaling comparable to state-of-the art work-stealing scheduler implementations---the Cilk++ compiler and the Java fork/join framework---despite the dramatic increase in generality.
