  • Improvements of Intra-Nuclear Cascade models stimulated by recent spallation data
    AIP Conference Proceedings, 2002
    Co-Authors: C. Volant, A. Boudard, J. Cugnon, S. Leray
    Abstract:

    In high-energy transport codes used to Design Accelerator Driven Systems or spallation neutron sources, elementary interactions are computed through nuclear physics models. Among these, Intra-Nuclear Cascade models play a major role since the excitation energy at the end of the INC stage determines the number of evaporated particles. Therefore, in simulation of spallation targets, INC influences the total number of emitted neutrons and the isotopic distribution of produced nuclei. Recent data regarding the production of neutrons and residual nuclei in proton induced reactions make it possible to now test the reliability of INC models and improve them. A new version (INCL4) of the Liege INC model will be presented.

  • ISCA Workshops - Computation vs. memory systems: pinning down Accelerator bottlenecks
    Computer Architecture, 2011
    Co-Authors: Martha A. Kim, Stephen A. Edwards
    Abstract:

    The world needs special-purpose Accelerators to meet future constraints on computation and power consumption. Choosing appropriate Accelerator architectures is a key challenge. In this work, we present a pintool Designed to help evaluate the potential benefit of accelerating a particular function. Our tool gathers cross-procedural data usage patterns, including implicit dependencies not captured by arguments and return values. We then use this data to characterize the limits of hardware procedural acceleration imposed by on-chip communication and storage systems. Through an understanding the bottlenecks in future Accelerator-based systems we will focus future research on the most performance-critical regions of the Design. Accelerator Designers will also find our tool useful for selecting which regions of their application to accelerate.
