    Summary form only given. Modern computing platforms provide huge amounts of computational power - the top supercomputers contain more than 100,000 cores, and volunteer computing grids gather millions of processors. Resource selection becomes critical for enabling scientific computing applications to fully harness such platforms: the more resources at our disposal, the more difficult the art of sel...

    This study considers a heterogeneous computing system and corresponding workload being investigated by the Extreme Scale Systems Center (ESSC) at Oak Ridge National Laboratory (ORNL). The ESSC is part of a collaborative effort between the Department of Energy (DOE) and the Department of Defense (DoD) to deliver research, tools, software, and technologies that can be integrated, deployed, and used ...

    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (884 KB) | HTML iconHTML

    The heterogeneous communication characteristics of clustered SMP systems create great potential for optimizations which favor physical locality. This paper describes a novel technique for automating such optimizations, applied to barrier operations. Portability poses a challenge when optimizing for locality, as costs are bound to variations in platform topology. This challenge is addressed through... View full abstract»

    Many computing environments are heterogeneous, i.e., they consist of a number of different machines that vary in their computational capabilities. These machines are used to execute task types that vary in their computational requirements. Characterizing heterogeneous computing environments and quantifying their heterogeneity is important for many applications. In previous research, we have propos... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (694 KB) | HTML iconHTML

    In this paper, we present an adaptive method for scheduling parallel applications on unspecified distributed memory platforms. The presented method can be used to schedule parallel applications when the total workload and the execution parameters (communication speed, available computing power...) are unspecified. When used to schedule divisible load applications according to a master worker model... View full abstract»

  • MO-Greedy: An Extended Beam-Search Approach for Solving a Multi-criteria Scheduling Problem on Heterogeneous Machines

    Cited by:  Papers (3)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1090 KB) | HTML iconHTML

    Optimization problems can often be tackled with respect to several objectives. In such cases, there can be several incomparable Pareto-optimal solutions. Computing or approximating such solutions is a major challenge in algorithm design. Here, we show how to use an extended beam-search technique to solve a multi-criteria scheduling problem for heterogeneous machines. This method, called MO-Greedy ... View full abstract»

  • A Model-Based Schedule Representation for Heterogeneous Mapping of Dataflow Graphs

    Dataflow-based application specifications are widely used in model-based design methodologies for signal processing systems. In this paper, we develop a new model called the dataflow schedule graph (DSG) for representing a broad class of dataflow graph schedules. The DSG provides a graphical representation of schedules based on dataflow semantics. In conventional approaches, applications are repre... View full abstract»

    High energy consumption has become a critical problem for supercomputer systems. GPU clusters are becoming an increasingly popular architecture for building supercomputers because of its great improvement in performance. In this paper, we first formulate the tasks mapping problem as a mini-mal energy consumption problem with deadline constraint. Its optimizing object is very different from the tra...

    Computing and communication devices in any cyber-physical system (CPS) of non-trivial scale exhibit significant heterogeneity. Critical infrastructure systems, which are prime examples of CPSs, are no exception. The extent of networking capability, decentralized control, and more generally, integration between the cyber and physical infrastructures can vary greatly within a large-scale CPS. Other ...

    Today, CUDA is the de facto standard programming framework to exploit the computational power of graphics processing units (GPUs) to accelerate various kinds of applications. For efficient use of a large GPU-accelerated system, one important mechanism is checkpoint-restart that can be used not only to improve fault tolerance but also to optimize node/slot allocation by suspending a job on one node...

    In this paper we are interested in large scale distributed platforms like BOINC, consisting of heterogeneous resources and using the Internet as underlying communication network. In this context, we study a resource clustering problem, where the goal is to build clusters having at least a given capacity and such that any two participants to the same cluster are not too far from each other. In this... View full abstract»

    This paper presents a framework for high-level power estimation of multiprocessor systems-on-chip (MPSoC) architectures on FPGA. The technique is based on abstract execution profiles, called event signatures, and it operates at a higher level of abstraction than, e.g., commonly-used instruction-set simulator (ISS) based power estimation methods and should thus be capable of achieving good evaluati...
