    Sites, Richard L. (2016-09-10)
    Conference report
    Open Access
    Computers used as datacenter servers have usage patterns that differ substantially from those of desktop or laptop computers. We discuss four key differences in usage and their first-order implications for designing computers ...
  • Simulating extreme hydro-meteorological events with DRIHM(2US) services 

    Parodi, Antonio (2016-09-10)
    Conference report
    Open Access
    From 1970 to 2012, about 9000 High Impact Weather Events (HIWE) were reported globally: all together, they caused the loss of 1.94 million lives and economic damage of US$ 2.4 trillion (2014 UNISDR report). Storms and ...
  • A New role of ontologies and advanced scientific visualization in big data analytics 

    Chuprina, Svetlana (2016-09-10)
    Conference report
    Open Access
    Accessing and contextual semantic searching structured, semi-structured and unstructured information resources and their ontology based analysis in a uniform way across text-free Big Data query implementation is a main ...
  • The Route towards the ultimate network topology 

    Rodriguez, German (2016-09-10)
    Conference report
    Open Access
    In this talk I will try to summarize our quest for a realizable network topology that optimizes performance, cost, power consumption and partitionability. We have explored Fat Trees, Dragonflies, variations of dragonflies, ...
  • Adaptive, efficient, parallel execution of parallel programs 

    Sohi, Guri (2016-09-10)
    Conference report
    Open Access
    Future parallel processors will be heterogeneous, be increasingly less reliable, and operate in dynamically changing operating conditions. This will result in a constantly varying pool of hardware resources which can greatly ...
  • VIPS: simple, efficient, and scalable cache coherence 

    Ros, Alberto (2016-09-10)
    External research report
    Open Access
    Directory-based cache coherence is the de-facto standard for scalable shared-memory multi/many-cores and significant effort is invested in reducing its overhead. However, directory area and complexity optimizations are ...
  • Towards real-time CFD simulation of in-flight icing 

    Habashi, Wagdi G. (2016-09-10)
    Conference report
    Open Access
    Despite the concerted efforts of manufacturers and certification agencies, incidents and accidents continue to happen to aircraft certificated to “Fly Into Known Icing”, falsely thought of as being “immune to in-flight ...
  • Semantically ordered parallel execution of multiprocessor programs 

    Sohi, Guri (2016-09-10)
    Conference report
    Open Access
    Nondeterministic execution of conventional, multithreaded programs complicates multiprocessor programming and system use in general. To eliminate nondeterminism from multiprocessor programs, we propose an ordered approach. ...
