    GPU Behavior on a Large HPC Cluster

    The authors discuss observed characteristics of GPUs deployed as accelerators in an HPC cluster at Los Alamos National Laboratory. GPUs have a very good theoretical FLOPS rate, and are reasonably inexpensive and available, but they are relatively new to HPC, which demands both consistently high performance across nodes and consistently...

    Reliability Models for Double Chipkill Detect/Correct Memory Systems

    Chipkill correct is an advanced type of error correction used in memory subsystems. Existing analytical approaches for modeling the reliability of memory subsystems with chipkill correct are limited to those with chipkill correct solutions that can only guarantee correction of errors in a single DRAM device. However, chipkill correct solutions...

    Stochastic Identification and Clustering of Malware with Dynamic Traces

    A novel approach to malware classification is introduced based on analysis of instruction traces that are collected dynamically from the program in question. The method can be applied on-line in a sandbox environment, and is intended for eventual host-based use, provided the engineering hurdle of sampling the instructions executed by...

    DRepl: Optimizing Access to Application Data for Analysis and Visualization

    Until recently most scientific applications produced data that is saved, analyzed and visualized at later time. In recent years, with the large increase in the amount of data and computational power available there is demand for applications to support data access in-situ, or close-to simulation to provide application steering, analytics...

    Equilibria in Topology Control Games for Ad Hoc Networks and Generalizations

    The authors study topology control problems in ad hoc networks where network nodes get to choose their power levels in order to ensure desired connectivity properties. Unlike most other work on this topic, the authors assume that the network nodes are owned by different entities, whose only goal is to...

    Interpretations of the Web of Data

    The emerging Web of Data utilizes the web infrastructure to represent and interrelate data. The foundational standards of the Web of Data include the Uniform Resource Identifier (URI) and the Resource Description Framework (RDF). URIs are used to identify resources and RDF is used to relate resources. While RDF has...

    A Locality-Aware Cooperative Cache Management Protocol to Improve Network File System Performance

    In a distributed environment the utilization of file buffer caches in different clients may vary greatly. Cooperative caching is used to increase cache utilization by coordinating the usage of distributed caches. Existing cooperative caching protocols mainly address organizational issues, paying little attention to exploiting locality of file access patterns. The...
