Heterogeneous computing platforms with multicore host system and many-core accelerator devices have taken a major step forward in the mainstream HPC computing market this year with the announcement of HP Apollo 6000 System's ProLiant XL250a server features the Intel (R) Xeon Phi (TM) coprocessors. Although many application developers attempt to use it in the same way as GPGPU acceleration platforms, doing so forfeits the processing capability of multicore host processors and introduces power inefficiency in business operations. In this paper, we propose an application optimization framework to turn sequential legacy applications into highly parallel applications that make use of the hardware resources both on the host CPU and on the accelerator devices to enable simultaneous heterogeneous computing. As a case study, we look at how to apply this framework and adopt a structured methodology to develop option pricing applications to take advantages of a heterogeneous computing environment.

Disciplined Inconsistency with Consistency Types 7

Disciplined Inconsistency with Consistency Types

7th ACM Symposium on Cloud Computing (SoCC)

Distributed applications and web services, such as online stores or social networks, are expected to be scalable, available, responsive, and fault-tolerant. To meet these steep requirements in the face of high round-trip latencies, network partitions, server failures, and load spikes, applications use eventually consistent datastores that allow them to weaken the consistency of some data. However, making this transition is highly error-prone because relaxed consistency models are notoriously difficult to understand and test. In this work, we propose a new programming model for distributed data that makes consistency properties explicit and uses a type system to enforce consistency safety. With the Inconsistent, Performance-bound, Approximate (IPA) storage system, programmers specify performance targets and correctness requirements as constraints on persistent data structures and handle uncertainty about the result of datastore reads using new consistency types. We implement a prototype of this model in Scala on top of an existing datastore, Cassandra, and use it to make performance/correctness tradeoffs in two applications: a ticket sales service and a Twitter clone. Our evaluation shows that IPA prevents consistency-based programming errors and adapts consistency automatically in response to changing network conditions, performing comparably to weak consistency and 2-10x faster than strong consistency.

Place-Based Investment model of Talent Development: A Proposed model for Developing and Reinvesting Talents Within the Community

引用

JOURNAL OF ADVANCED ACADEMICS 2016年第4期27卷 311-342页

作者： Paul, Kristina Ayers Seward, Kristen K. Purdue Univ W Lafayette IN 47907 USA

The place-based investment model (PBIM) of talent development is a programming model for developing talents of high-potential youth in ways that could serve as an investment in the community. In this article, we discuss the PBIM within rural contexts. The model is grounded in three theories-Moon's personal talent development theory, Sternberg's theory of successful intelligence, and social cognitive career theory-and specifies five pathways for developing talent: (a) enrichment, (b) advanced learning, (c) human connections, (d) entrepreneurial thinking, and (e) specialized guidance. Through this proposal, we intend to focus place-based talent development efforts in rural areas on giving high-potential young people the knowledge, skills, and tools for understanding themselves, for developing their strengths and passions, and for recognizing localized opportunities for achieving self-fulfillment in adulthood.

The current trend in development of parallel programming models is to combine different well established models into a single programming, model in order to support efficient implementation of a wide range of real world applications. The dataflow model has particularly managed to recapture the interest of the research community due to its ability to express parallelism efficiently. Thus, a number of recently proposed hybrid parallel programming models combine dataflow and traditional shared memory models. Their findings have influenced the introduction of task dependency in the OpenMP 4.0 standard. This article presents DaSH - the first comprehensive benchmark suite for hybrid dataflow and shared memory programming models. DaSH features 11 benchmarks, each representing one of the Berkeley dwarfs that capture patterns of communication and computation common to a wide range of emerging applications. DaSH also includes sequential and shared-memory implementations based on OpenMP and Intel TBB to facilitate easy comparison between hybrid dataflow implementations and traditional shared memory implementations based on work-sharing and/or tasks. Finally, we use DaSH to evaluate three different hybrid dataflow models, identify their advantages and shortcomings, and motivate further research on their characteristics. (C) 2015 Elsevier B.V.

programming model and tools for embedded multicore systems

INTERNATIONAL JOURNAL OF EMBEDDED SYSTEMS 2010年第3-4期4卷 259-269页

Multicore programming is more difficult than single-core programming, and developing applications on a complex multicore system without using an appropriate development environment is difficult, with the results being highly prone to error. A useful development environment for an embedded application design should contain programming models and development tools. The programming model provides a higher abstract level to control the communication and execution of multicore hardware, while the development tools help developers to debug applications and measure the performance of applications. In this paper, we propose a development environment for embedded multicore systems that includes a heterogeneous multicore simulation platform, customised compiler tools for a VLIW DSP, and a multicore programming model, streaming RPC. The experimental results demonstrate the high performance of the multicore simulation and compiler optimisations. The performance of compiled MiBench with O2 optimisation was 70% relative to no optimisation.

A New Compilation Flow for Software-Defined Radio Applications on Heterogeneous MPSoCs

ACM TRANSACTIONS ON ARCHITECTURE AND CODE OPTIMIZATION 2016年第2期13卷 19-19页

The advent of portable software-defined radio (SDR) technology is tightly linked to the resolution of a difficult problem: efficient compilation of signal processing applications on embedded computing devices. Modern wireless communication protocols use packet processing rather than infinite stream processing and also introduce dependencies between data value and computation behavior leading to dynamic dataflow behavior. Recently, parametric dataflow has been proposed to support dynamicity while maintaining the high level of analyzability needed for efficient real-life implementations of signal processing computations. This article presents a new compilation flow that is able to compile parametric dataflow graphs. Built on the LLVM compiler infrastructure, the compiler offers an actor-based C++ programming model to describe parametric graphs, a compilation front end for graph analysis, and a back end that currently matches the Magali platform: a prototype heterogeneous MPSoC dedicated to LTE-Advanced. We also introduce an innovative scheduling technique, called microscheduling, allowing one to adapt the mapping of parametric dataflow programs to the specificities of the different possible MPSoCs targeted. A specific focus on FIFO sizing on the target architecture is presented. The experimental results show compilation of 3GPP LTE-Advanced demodulation on Magali with tight memory size constraints. The compiled programs achieve performance similar to handwritten code.

With Internet of Things (IoT) technology, home environment becomes smarter than ever. Not only smart devices such as smart phone or smart TV, but also various IoT devices including sensor, smart thermostat, and smart scale has now become very common on the market. These devices have connectivity to the Internet, so that user can read data from the device or control the device using Internet technology. However, due to diversity of smart home requirements, device collaboration in smart home remains a challenging task still. Usually smart home is built with various technologies to fulfill its own purpose, and these purposes cover very wide area from controlling low-power sensor devices to controlling high-performance devices like smart TV and smart phone. This variety of smart home requirements makes smart home very complicated due to mixed network architecture, protocol and technology. In this paper, a framework to enable managing and collaborating heterogeneous IoT devices in smart home environment is proposed. Several programming models are defined in the proposed framework to make application development for heterogeneous devices more intuitive. The proposed framework has been implemented as a web service, and a case study with real-world smart home IoT devices is presented.
