Pneumatic positioning systems have always been attractive for robotics and automation applications due to their high power-to-weight ratio and low cost. On the other hand, achieving fast and accurate control of their position have been known as a complex control problem and in fact it has not been solved yet in a 100% percentage of position accuracy and repeatability. A smart way to implement the three term classical control approach (PID) to such a system is presented in this paper. The I-Term was selected to be "switched" on and off, dynamically and automatically, according to the system control requirements. Although the task sounds challenging for an engineer, the primary aim of this research project is to design and implement an advanced electrical board which will be the embedded interface between an engineer and a pneumatic positioning plant. The interface board will include a microcontroller and all necessary peripheral circuitry as well as the software environment where the control code will be composed. Low cost, easy to pick-up from a local store electrical equipment will be used that can operate under non up to date computer connection thus minimizing the cost of the whole system further. Reliability, low cost and ease of use of the board are critical design factors. The feedback data of the pneumatic system performance will be monitored in a computer monitor via the board's data acquisition operation in real time.

This paper describes the use of array notation called Parray in refinement of parallel programs concerning array type that separates the physical data layout and logical structure of multi-dimensional data, and the control flow diversion of heterogeneous processor units. A case study on matrix multiplication demonstrates refinement of Parray programs: the code evolves from a simple single CPU-thread code to a multi-thread code on CPU/MIC and then a GPU code by modifying the array types in only a few lines of code. A GPU-based SGEMM is implemented in Parray and achieves almost the same Gflops of CUBLAS 4.0 when testing on a single node of Tian-1A system. Because the code operates directly on the logical structure of array, the same SGEMM code can work on different physical array data layouts.

In the past decades, integrated development environments (IDEs) have been largely advanced to facilitate software engineering tasks and improve developer productivity. Yet, with growing information needs driven by increasing complexity in developing modern software with demands for high quality and reliability, developers often need to switch among multiple user interfaces, even across different applications, in their development process, which breaks their mental workflow thus tends to adversely affect their work efficiency and productivity. This paper discusses challenges faced by the current IDE design mainly due to working context transitions imposed on developers during their search for multiple information sources for their development needs. It remarks the primary blockades behind and initially explores some high-level design considerations for overcoming such challenges in the next-generation IDEs. Specifically, a few design enhancements on top of modern IDEs are proposed, attempting to reduce the overheads of frequent context switching commonly seen in the multitasking practice of developers.

epiC: an Extensible and Scalable System for Processing Big Data

The Big Data problem is characterized by the so-called 3V features: volume - a huge amount of data, velocity - a high data ingestion rate, and variety - a mix of structured data, semi-structured data, and unstructured data. The state-of-the-art solutions to the Big Data problem are largely based on the MapReduce framework (aka its open source implementation Hadoop). Although Hadoop handles the data volume challenge successfully, it does not deal with the data variety well since the programming interfaces and its associated data processing model are inconvenient and inefficient for handling structured data and graph data. This paper presents epiC, an extensible system to tackle the Big Datas data variety challenge. epiC introduces a general Actor-like concurrent programming model, independent of the data processing models, for specifying parallel computations. Users process multi-structured datasets with appropriate epiC extensions, and the implementation of a data processing model best suited for the data type and auxiliary code for mapping that data processing model into epiCs concurrent programming model. Like Hadoop, programs written in this way can be automatically parallelized and the runtime system takes care of fault tolerance and inter-machine communications. We present the design and implementation of epiCs concurrent programming model. We also present two customized data processing models, an optimized MapReduce extension and a relational model, on top of epiC. We show how users can leverage epiC to process heterogeneous data by linking different types of operators together. To improve the performance of complex analytic jobs, epiC supports a partition-based optimization technique where data are streamed between the operators to avoid the high I/O overheads. Experiments demonstrate the effectiveness and efficiency of our proposed epiC.

This paper discusses the utilization of modular hardware devices in an educational context. As the leading platform for such purposes, we first describe the ingredients at the origin of Arduino's success. Examples of student projects and seminars based on this platform will illustrate how Arduino triggers innovation by providing an accessible programming interface and rich reusable content. Based on several experiences, we describe the design of a platform environment for smart wireless sensors reusing key concepts from Arduino to facilitate and accelerate development and deployment time. The usage of the new platform and design interface in student projects is described as well.

MLI is an Application programming interface designed to address the challenges of building Machine Learning algorithms in a distributed setting based on data-centric computing. Its primary goal is to simplify the development of high-performance, scalable, distributed algorithms. Our initial results show that, relative to existing systems, this interface can be used to build distributed implementations of a wide variety of common Machine Learning algorithms with minimal complexity and highly competitive performance and scalability.

The purpose of this paper is describing a semantics-driven approach to the automatic segmentation of song lyrics. The proposed algorithm takes into account the basic formatting commonly in use for lyrics on CD booklets and specialized Web sites, in order to extract basic semantic information, such as the organization in lines and sections. Then the algorithm applies simple rules to reconstruct lyrics structure, supporting tolerance margins as regards possible errors and encoding variants. The output is a sequence of sections labelled according to the similarity of their contents. The resulting segmenter is publicly available as a set of methods exposed via a Web application programming interface (API).

PACHA: Low Cost Bare Metal Development for Shared Memory Manycore Accelerators

引用

Procedia Computer Science 2013年 18卷 1644-1653页

Today, efficiently implementing an application on shared memory manycore accelerators is a hard task. Linux eases the development, but is not adapted to exploit the maximum of the platform yet. Bare metal programming environments provided with accelerators give a low-overhead access to the platform. However, they increase the complexity of development, mainly due to 4 gaps: each accelerator has its own specific environment; bare metal environments are only supported on the hardware platform or on the proprietary simulator; they have seldom, if ever, execution debugging support; they do not have parallel programming models, and whenever they exist, they are platform-specific. In order to fill the gaps and thus, to lower the barrier to develop on bare metal on shared memory manycore accelerators, we present PACHA. It features two aspects: a low overhead, Platform Agnostic, Close-to-HArdware (PACHA) programming interface, which allows to handle only one version of the application code for all supported accelerators, and an easy-to-use multi-platform development environment, which abstracts the complexity of each accelerator's development environment. With a x86 support and a Linux compatibility, PACHA offers a functional simulator and all the Linux set of debugging tools. Further, based on the programming interface, three parallel execution models have been ported in order to facilitate the devel- opment and comparison of applications. PACHA is currently fully supported for x86 platforms, TILEPro64 and STHORM. A case study on a TILEPro64 is presented: the performance gain using PACHA rather than Linux with OpenMP or Pthread is about 1,8x to 4x, without increasing the development cost.
