    Abstract: The Abisko project aims to develop an energy-efficient spiking neural network (SNN) computing architecture and software system capable of autonomous learning and operation. The SNN architecture explores novel neuromorphic devices that are based on resistive-switching materials, such as memristors and electrochemical RAM. Equally important, Abisko uses a deep codesign approach to pursue this goal by engaging experts from across the entire range of disciplines: materials, devices and circuits, architectures and integration, software, and algorithms. The key objectives of our Abisko project are threefold. First, we are designing an energy-optimized high-performance neuromorphic accelerator based on SNNs. This architecture is being designed as a chiplet that can be deployed in contemporary computer architectures and we are investigating novel neuromorphic materials to improve its design. Second, we are concurrently developing a productive software stack for the neuromorphic accelerator that will also be portable to other architectures, such as field-programmable gate arrays and GPUs. Third, we are creating a new deep codesign methodology and framework for developing clear interfaces, requirements, and metrics between each level of abstraction to enable the system design to be explored and implemented interchangeably with execution, measurement, a model, or simulation. As a motivating application for this codesign effort, we target the use of SNNs for an analog event detector for a high-energy physics sensor.

    Abstract: To support creation of nimble applications for computational grids, the authors believe one must eliminate the barrier that separates program creation from execution and post-mortem optimization. This paper outlines an approach to dynamic performance adaptation and distributed optimization in the grid environment based on a suite of performance instrumentation, analysis, and presentation tools that includes distributed performance sensors and resource policy actuators, fuzzy logic rule bases for adaptive control, and immersive visualization systems for real-time visualization and direct manipulation of software behavior.

    Abstract: This case study presents an analytical performance model for the DARPA UHPC streaming sensor challenge problem developed using Aspen, a domain-specific language for performance modeling. The model focuses on the exploration of algorithmic tradeoffs, data structures and storage, and the impact of an important tiling factor in the image formation kernel of a synthetic aperture radar image-processing computation.

    Abstract: In 2005, Oak Ridge National Laboratory (ORNL) received delivery of a 5294 processor Cray XT3. The XT3 is Cray's third-generation massively parallel processing system. The ORNL system uses a single-processor node built around the AMD Opteron and uses a custom chip—called SeaStar—for interprocessor communication. The system uses a lightweight operating system called Catamount on its compute nodes. This paper provides a performance evaluation of the Cray XT3, including measurements for micro-benchmark, kernel, and application benchmarks. In particular, we provide performance results for strategic Department of Energy applications areas including climate, biology, astrophysics, combustion, and fusion. Our results, on up to 4096 processors, demonstrate that the Cray XT3 provides competitive processor performance, high interconnect bandwidth, and high parallel efficiency on a diverse application workload, typical in the DOE Office of Science.

    Abstract: As systems of computers become more compleX in terms of their architecture, interconnect and heterogeneity, the optimum configuration and utilization of these machines becomes a major challenge. To reduce the penalties caused by poorly configured systems, simulation is often used to predict the performance of key applications to be eXecuted on the new systems. Simulation provides the capability to observe component and system characteristics (e.g. performance and power) in order to make vital design decisions. However, simulating high-fidelity models can be very time consuming and even prohibitive when evaluating large-scale systems. The Fast and Accurate Simulation Environment (FASE) framework seeks to support large-scale system simulation by using high-fidelity models to capture the behavior of only the performance-critical components while employing abstraction techniques to capture the effects of those components with little impact on the system. In order to achieve this balance of accuracy and simulation speed, FASE provides a methodology and associated toolset to evaluate numerous architectural options. This approach allows users to make system design decisions based on quantifiable demands of their key applications rather than using manual analysis which can be error prone and impractical for large systems. The framework accomplishes this evaluation through a novel approach of combining discrete-event simulation with an application characterization scheme in order to remove unnecessary details while focusing on components critical to the performance of the application. In this paper, we present the methodology and techniques behind FASE and include several case studies validating systems constructed using various applications and interconnects.
