Performance modeling is important for implementing efficient parallel applications and
runtime systems. The LogP model captures the relevant aspects of message passing in …

The performance of the MPI's collective communications is critical in most MPI-based
applications. A general algorithm for a given collective communication operation may not …

To better manage the ever increasing complexity of LAM/MPI, we have created a lightweight
component architecture for it that is specifically designed for high-performance message …

During the software crisis of the 1960s, Dijkstra's famous thesis" goto considered harmful"
paved the way for structured programming. This short communication suggests that many …

Initial versions of MPI were designed to work efficiently on multi-processors which had very
little job control and thus static process models. Subsequently forcing them to support a …

In Vehicular Ad Hoc Networks (VANETs), moving vehicles are considered as mobile nodes
in the network and they are connected to each other via wireless links when they are within …

Metacomputing infrastructures couple multiple clusters (or MPPs) via wide-area networks. A
major problem in programming parallel applications for such platforms is their hierarchical …

As large-scale clusters become more distributed and heterogeneous, significant research
interest has emerged in optimizing MPI collective operations because of the performance …

This paper proposes a new diminished reality method for 3D scenes considering
background structures. Most conventional methods using image inpainting assumes that the …

Several MPI systems for grid environment, in which clusters are connected by wide-area
networks, have been proposed. However, the algorithms of collective communication in …
