An object-oriented library for shared-memory parallel simulations
… on the Mint MIPS architecture simulator. Simulations are run both with parameters similar to current multiprocessor architectures, and with higher memory hierarchy costs, to investigate the impact of technology trends. OOSH versions of the applications are compared with the SPLASH …

Efficient parallel simulations and their application to communication networks
… computing systems (e.g., tightly-coupled parallel computers or distributed networks of workstations), parallel simulation, which parallelizes a simulation program for execution on multiple processors, becomes an attractive means to reduce simulation execution time. With few exceptions, …

Parallel Simulations, Reduced-Order Modeling, and Feedback Control of Vortex Shedding using Fluidic Actuators
… observed in many bluff body wakes. We develop a parallel computational fluid dynamics (CFD) code to solve the incompressible Navier-Stokes equations on curvilinear coordinates to analyze vortex shedding. The algorithm is implemented on a distributed-memory, message-passing parallel computer, and …

Utilizing Hierarchical Clusters in the Design of Effective and Efficient Parallel Simulations of 2-D and 3-D Ising Spin Models
In this work, we design parallel Monte Carlo algorithms for the Ising spin model on a hierarchical cluster. A hierarchical cluster can be considered as a cluster of homogeneous nodes which are partitioned into multiple supernodes such that communication across homogenous clusters is represented by …

The cost of terminating parallel discrete-event simulations
… different rules to decide when to terminate. Parallel simulations generally use a single, simple rule: each process comprising the simulation terminates after a predefined period of time. A number of parallel simulation protocols have been proposed that enforce constraints on the order in …

Characterization, modeling, and simulation of multiscale directed-assembly systems
… to directed-assembly. We employ massively parallel simulations, enabled by custom software, to establish underlying system dynamics and develop new device production methods.

Terminating parallel discrete event simulations
… and collecting output measures in discrete event simulations. With regard to parallel simulations, this problem is inherently more difficult than the classic termination detection problem for two reasons. The first is that parallel simulation processes are often written as nonterminating; the …

A stabilized finite element dynamic overset method for the Navier-Stokes equations
… a more economic means of obtaining accurate simulations and/or to resolve physics at scales not possible with lower-order schemes. For simulations that may have large relative motion between multiple bodies, overset grid methods have demonstrated distinct advantages over mesh movement …

Load Balancing Scientific Applications
… For ideal efficiency, developers of the simulations that run on these machines must ensure that computational work is evenly balanced among processors. Assigning work evenly is challenging because many large modern parallel codes simulate behavior of physical systems that evolve over …

A multiscale computational framework for the simulation of local features in large structures
… among multiple spatial scales through numerical simulations. Resolving fine-scale features such as geometrical details, cracks, and localized nonlinearities with high fidelity is crucial for the accurate prediction of the response and service life of structural components. Three-dimensional …

A methodology based on local resolution of turbulent structures for effective modeling of unsteady flows
… the industry has seen a continuous growth of CFD simulations of turbulent phenomena, which has been made possible by the tremendous reduction achieved in cost per floating point operation. The need for accurate, yet computationally effective, transient methods has drawn particular attention to …
