We consider the problem of dynamic provisioning of an end-to-end optical path that is subject to certain user and network constraints and spanning multiple wavelength-routed WDM optical domains. We propose a hierarchical connection-provisioning algorithm for the computation and setup of the end-to-end constraint-based path. We present initial results for… (More)

The Uintah Software framework was developed to provide an environment for solving fluid-structure interaction problems on structured adaptive grids on large-scale, long-running, data-intensive problems. Uintah uses a combination of fluid-flow solvers and particle-based methods for solids together with a novel asynchronous task-based approach with fully… (More)

We consider the problem of dynamically provisioning an end-to-end optical path that spans multiple wavelength-routed WDM optical domains. We examine the associated algorithms for intra- and inter domain light path computation and wavelength assignment. We particularly study two different schemes: combined shortest path first (combSPF) and the multidomain… (More)

The design of robust computational physics codes has always been a challenge to application programmers. One of the key difficulties in writing multiphysics codes stems from the inefficient handling of spatial discretization and field operations. For example, in the context of the finite volume (FV) method, one often deals with structured and unstructured… (More)

The Uintah computational framework is used for the parallel solution of partial differential equations on adaptive mesh refinement grids using modern supercomputers. Uintah is structured with an application layer and a separate runtime system. The Uintah runtime system is based on a distributed directed acyclic graph (DAG) of computational tasks, with a… (More)

This paper deals with the implementation and performance analysis of a parallel Algebraic Multigrid Solver (pAMG) for a finite volume unstructured CFD code. The parallelization of the solver is based on the domain decomposition approach using the single program multiple data paradigm. The Message passing interface Library (MPI) is used for communication of… (More)
