    The transmission control protocol (TCP) is the major trans- port layer protocol in the Internet today. TCP and its vari- ants have the drawback of not knowing the explicit rate share of flows at bottleneck links. The ...

  • Wei, Mingliang; Snir, Marc; Torrellas, Josep; Tremaine, R. Brett (2005-02)
    Many important scientific and engineering applications execute sub-optimally on current commodity processors and servers. Specifically, since they frequently use caches ineffectively, they are often heavily bottlenecked ...

    The transmission control protocol (TCP) is the major trans- port protocol in the Internet. TCP and its variants have the drawback of not accurately knowing rate share of flows at bottleneck links. Some protocols proposed ...

    We propose in this paper a new approach to study the temporal and spatial locality of codes using a plot of cache miss bandwidth as a function of cache size and line size for a fully associative LRU cache. We apply this ...

    A linear differential operator often has a nontrivial null space. One consequence for such an operator, L, is that solutions of equations of the form Lu=f are never unique if the null space contains more than the zero ...
